Re: [Nagios-users] Distributed monitoring: central collector doesn't seem to be able to run active checks
I'm continuing to iron out the wrinkles with 3.5.1 and distributed monitoring. I'm using mod_gearman to submit and receive events from two distributed pollers. Every now and again, I'll get something similar in the log on the centralized collecting machine: CRITICAL: Return code of 127 is out of bounds. Make sure the plugin youre trying to run actually exists. (worker: collector.domain.org) To me, that suggests that the collector system didn't get a result for a host or service in a timely manner from one of the polling systems, and so it attempted to run an active check itself. However, it doesn't seem to be able to, and I don't know why. The collector has the same value for $USER1$, and it has the same set of plugins installed on it: On the collector: grep USER1 etc/resource.cfg $USER1$=/usr/local/nagios/libexec On the two pollers: $USER1$=/usr/local/nagios/libexec $USER1$=/usr/local/nagios/libexec The plugins are installed in identical locations on all three systems, that's enforced via Puppet. The 'nagios' user can find and run them on the collector: /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 NRPE v2.13 Now, because this is a distributed setup, the collector system is not configured to run active checks: grep ^execute etc/nagios.cfg execute_service_checks=0 execute_host_checks=0 ... but *obviously* it's trying to. Is it failing because it's configured to not run them? If that's the case, the error message is not accurate and should be corrected. If that's *not* the case, why can't my collector server run an active check when it believes it needs to? I use NConf to generate my configurations, if that matters. There are a *lot* of hosts/services and quite a few configuration files, so I'm not going to paste a slew of information here. If I'm missing pertinent information, please let me know exactly what you want to see and I'll get it. No one has an idea about this? And no, Andreas, I can't move to 4.0 yet. ;) Thanks!

Re: [Nagios-users] Distributed monitoring: central collector doesn't seem to be able to run active checks
Do you get many of those error messages in the logs at once, or just one at a time? Only one thought: what are the permissions on your $USER$ variables? Nagios on my systems setuid() to nonroot after startup, and if it gets SIGHUP to reload config, but can't read the file defining $USER*$, will act strangely. Just one at a time, seemingly randomly. A host here, a service there, several times a day. They always almost immediately recover, but I don't understand why my centralized collector seems to have this issue. Nagios runs as the nagios user, which can read the resource.cfg file fine: ls -ld . ; ls -l nagios-hostname.cfg resource.cfg drwxrwx--- 6 root nagios 4096 Aug 27 16:02 . -rw-r--r-- 1 root root 47606 Jul 1 11:18 nagios-hostname.cfg -rw-r- 1 root nagios 2400 Mar 19 11:25 resource.cfg Thanks! -- No matter how tempted I am with the prospect of unlimited power, I will not consume any energy field bigger than my head. -- #22 on Peter Anspach's Evil Overlord list -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

(worker: collector.domain.org) Hi, if this is the collector host, why does it have a mod-gearman worker installed? If nagios would have run the check by itself, there would be no hint about the worker in the error. So it seems like there is a worker started on your collector host which then grabs some checks but isn't able to execute them. Oh ho! I have multiple *gearman* processes running: ps axuww | grep gearman gearmand 5662 0.7 0.1 404672 2496 ?Ssl Aug17 118:29 /usr/sbin/gearmand -d -l /var/log/gearmand/gearmand.log nagios5712 0.0 0.0 38024 640 ?Ss Aug17 1:03 /usr/bin/mod_gearman_worker -d --config=/etc/mod_gearman/mod_gearman_worker.conf --pidfile=/var/mod_gearman/mod_gearman_worker.pid nagios 25919 0.0 0.1 137492 3016 ?S07:38 0:00 /usr/bin/mod_gearman_worker -d --config=/etc/mod_gearman/mod_gearman_worker.conf --pidfile=/var/mod_gearman/mod_gearman_worker.pid .. etc .. Are you saying I just need gearmand running on the collector? I'm quite new to gearman, so I might have misunderstood which parts are necessary where. I can easily shut down the mod_gearman_worker service, I just need to understand the consequences. I assumed that this was a Nagios error - perhaps I just have my gearman setup configured wrong.

On 8/28/13 14:43, C. Bensend wrote: Are you saying I just need gearmand running on the collector? Well, i assumed it. You are the only one which really can tell that. You will need a worker on each host which should run checks. If your collector should not run any checks, than no worker is necessary. See http://labs.consol.de/nagios/mod-gearman/#_common_scenarios for a list of common setups. OK, yes, I grok that. I guess I would want the collector to be *able* to run checks, if it doesn't get timely information from the pollers. I'm assuming that's why it's even trying in the first place - it doesn't see a result in a timely manner, so it thinks it should run one. Which circles back to my original question - why can't it run the check? Why isn't it finding what it needs to find? The workers are running as the nagios user, and I don't see anything that appears pertinent in the mod_gearman_worker.conf file... What am I missing? Neither the gearmand.log nor the mod_gearman_worker.log files seem to have any complaints (but I haven't bumped up the debug on them yet). Thanks so much for your help!

Re: [Nagios-users] Misplaced advice in the Nagios preflight check?
I can't seem to parse It doesn't make sense to get a recovery notification for something you never knew was a problem. Are you saying that since Nagios doesn't consider an unknown a problem, it won't send a recovery? Because it does... And in this case, I certainly want to know when a service having a monitoring issue (unknown) recovers. Not sure what you meant there. Thanks! Benny This is by design, and it is only a warning message. The config is valid and should work as you intended. It doesn't make sense to get a recovery notification for something you never knew was a problem. Unknowns are not considered problems in Nagios logic.

Re: [Nagios-users] Misplaced advice in the Nagios preflight check?
see the original language here: http://nagios.sourceforge.net/docs/3_0/notifications.html Note: Notifications about host or service recoveries are only sent out if a notification was sent out for the original problem. It doesn't make sense to get a recovery notification for something you never knew was a problem. And: http://nagios.sourceforge.net/docs/3_0/escalations.html If, after three problem notifications, a recovery notification is sent out for the service, who gets notified? The recovery is actually the fourth notification that gets sent out. However, the escalation code is smart enough to realize that only those people who were notified about the problem on the third notification should be notified about the recovery. In this case, the nt-admins and managers contact groups would be notified of the recovery. (Although, I believe I've either misunderstood the implications of that statement, or run into misbehaviours in that area myself...) Ah. Well, yes. :) I believe those statements are referring to the filters that Nagios uses to determine whether or not to send a notification at all. *That's* not an issue here, the notification goes out, just like it should. *My* question is why the sanity check thinks that configuration doesn't make sense. I think the answer is probably something to the effect of: I don't know why anyone would want that, so warn about it. I don't want to put words in the mouth of any of the developers that may have touched it, though, so I'm just guessing. I just want to make sure this is a case of Nagios maybe not giving the right advice in its sanity check, and *not* that there's something behind the scenes that I'm not aware of that might actually cause a problem. If it's the former, maybe we can get it adjusted for the next release. If it's the latter, I hope someone will step forth with the ClueBat 5000(tm) and give me a good thump. :) Thanks, everyone!

Have you tried giving that contact the extra options Nagios wants, and then defining a service escalation for that contact with the escalation_options directive set to u? No, I haven't. It *seems* to be working as I intend. My question is more as to why Nagios seems to think it's a bad idea, when it's a perfectly legitimate configuration. Are there unforeseen consequences that I'm not aware of? Or was it just not a configuration anyone thought would be useful/valid, so it is warned about? -- The very existence of flamethrowers proves that sometime, somewhere, someone said to themselves, 'You know, I want to set those people over there on fire, but I'm just not close enough to get the job done.' -- George Carlin -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
[Nagios-users] Misplaced advice in the Nagios preflight check?
Hey folks,
Still ironing out the wrinkles in my 3.5.0 distributed environment.
Yesterday, I added a new contact, and on preflight check it seemed
to think that what I did wasn't smart:
Jun 6 15:11:02 hostname nagios: Warning: Service recovery notification
option for contact 'cbensend-unknown-only' doesn't make any sense -
specify critical and/or warning options as well
Here's the contact I added that it seems to think is a dumb idea:
define contact {
contact_namecbensend-unknown-only
alias C. Bensend - unknown alerts only
host_notification_options n
service_notification_optionsu,r
email m...@myjob.com
host_notification_period24x7
service_notification_period 24x7
host_notification_commands notify-host-by-email
service_notification_commands notify-service-by-email
}
Not real sure why Nagios doesn't think that's a valid config - I
want a contact that will receive only UNKNOWN alerts for services.
Perfectly valid idea to me; I have a number of services that I
truly do not give a crap about, they trip many times a day and are
critical for some developers, but I don't do anything about them.
I *do*, however, want to know if there's a problem monitoring them,
hence the need to see UNKNOWN alerts and recoveries.
Is there some reason Nagios would think that's not valid? Or
should it not complain about that?
Just curious... It loaded the config and the contact exists, just
not entirely convinced it's a valid complaint. :)
Thanks much!
Benny

Ok - if I look at your output, manually, when the plugin is run as
the root user it produces the correct result.
But, you haven't said what the nrpe user is that is running on the
remote node and whether the same manual run of the check produces
the same output.
For example, I run remote plugins through nrpe as the nagios user
so if I want to manually test a plugin on the remote node, I would
first login as the nagios user to ensure I've got the same
environment that would be used when running via nrpe. It might be
that the variables you have set in the script only work as the root
user. It's never a good idea to test as the root user but only as
the same user as that used by nagios or nrpe.

That 'echo $?' was supposed to be on the next line, not a continuation of
the command. Can you run that again, but as two separate commands, one
right after the other? I want to see the result of your first command
(the iptables one).

I'm assuming server == zurich, right?
I wonder if you can cut out the first grep and awk, and just look for
'Cid' ?

Ok - if I look at your output, manually, when the plugin is run as
the root user it produces the correct result.
But, you haven't said what the nrpe user is that is running on the
remote node and whether the same manual run of the check produces
the same output.
For example, I run remote plugins through nrpe as the nagios user
so if I want to manually test a plugin on the remote node, I would
first login as the nagios user to ensure I've got the same
environment that would be used when running via nrpe. It might be
that the variables you have set in the script only work as the root
user. It's never a good idea to test as the root user but only as
the same user as that used by nagios or nrpe.

[Nagios-users] Nagios v3.5.0 transitioning immediately to a HARD state upon host problem
Hey folks,
I recently made two major changes to my Nagios environment:
1) I upgraded to v3.5.0.
2) I moved from a single server to two pollers sending passive
results to one central console server.
Now, this new distributed system was in place for several months
while I tested, and it worked fine. HOWEVER, since this was running
in parallel with my production system, notifications were disabled.
Hence, I didn't see this problem until I cut over for real and
enabled notifications.
(please excuse any cut-n-paste ugliness, had to send this info from
my work account via Outlook and then try to cleanse and reformat
via Squirrelmail)
As a test and to capture information, I reboot 'hostname'. This
log is from the nagios-console host, which is the host that accepts
the passive check results and sends notifications. Here is the
console host receiving a service check failure when the host is
restarting:
May 22 15:57:10 nagios-console nagios: SERVICE ALERT: hostname;/var disk
queue;CRITICAL;SOFT;1;Connection refused by host
So, the distributed poller system checks the host and sends its
results to the console server:
May 22 15:57:30 nagios-console nagios: HOST
ALERT:hostname;DOWN;SOFT;1;CRITICAL - Host Unreachable (a.b.c.d)
And then the centralized server IMMEDIATELY goes into a hard state,
which triggers a notification:
May 22 15:57:30 nagios-console nagios: HOST ALERT:
hostname;DOWN;HARD;1;CRITICAL - Host Unreachable (a.b.c.d)
May 22 15:57:30 nagios-console nagios: HOST NOTIFICATION:
cbensend;hostname;DOWN;host-notify-by-email-test;CRITICAL -
Host Unreachable (a.b.c.d)
Um. Wat? Why would the console immediately trigger a hard
state? The config files don't support this decision. And this
IS a problem with the console server - the distributed monitors
continue checking the host for 6 times like they should. But
for some reason, the centralized console just immediately
calls it a hard state.

Re: [Nagios-users] Nagios v3.5.0 transitioning immediately to a HARD state upon host problem
I ran into a similar problem, because my template set the service to * is_volatile=1*. http://nagios.sourceforge.net/docs/3_0/volatileservices.html Hrmmm. Good point... However, is_volatile does not appear in any of my configuration files, for any of the Nagios servers. It isn't set by default, is it? The Nagios config.cgi page doesn't even list it, and livestatus (what I use to query my running daemon) doesn't give it as a column it can query. I can't imagine it's on by default in v3.5.0, but I can't really tell if it is or not. I can try explicitly *disabling* it in all hosts, but I can't really test that at the moment - out of here for a long weekend in a few minutes. If it gets annoying enough over the weekend, I might *have* to test that theory. Thank you very much. I will still appreciate any input others can give on this question - it just doesn't seem to be behaving as it's configured!

Re: [Nagios-users] check_nt - MEMORY USAGE - incorrect results
Not entirely accurate. I just started troubleshooting a Win2008 R2 system yesterday - it has 16GB of physical RAM + 16 GB pagefile for a total of 32GB of virtual memory. The system is using 10.9GB of physical RAM, yet check_nt tells me it's using 2.69GB.

Re: [Nagios-users] Inconsistency of Nagios
I think you'll have to write one... check_procs is not helpful in this case, as the daemon forks off many processes to run plugins. Just checking for number of Nagios processes won't help, as it won't be aware of parent/child relationships. Now, mind you, I *do* run check_procs on my Nagios servers just to make sure I don't have runaways. But it won't tell me if I have more than one daemon running. If you really want to work on this, you'll have to write a plugin that is able to follow the parent/child relationships (take a look at the ps man page) and is able to determine if there's more than one parent process. I *think* that is a decent direction to go.

Re: [Nagios-users] Inconsistency of Nagios
If I understand correctly, I should create some plugin to kill all dependency process on a periodic interval. In my observation I did not see multiple parent process. My recommendation was to write a plugin to *detect* multiple parents, not kill them. Currently what I observe is whenever I see such sluggishness then I stop nagios service cleanup checkresult directory and start nagios again. However, with your further note above, I don't think you're getting multiple daemons running.

Re: [Nagios-users] Weird Nagios Problem
I have been running Nagios for over a year with no issues. All of a sudden, all of my current loads on my linux servers all go into warning state at the same time, showing the exact same load, which then increments every hour to critical. After a while (3 or 4 hours) they all come back down to normal. Checking on the servers themselves using HTOP shows normal load levels throughout the time period. Hmmm, yeah. Check that service and checkcommand definition. I bet you're actually testing the load on the *Nagios* server, and not the individual servers you think you're testing it on.

[Nagios-users] Distributed monitoring: v3.4.1 not translating host states like it should
Hey folks, I am in the process of implementing a distributed monitoring architecture, and I'm having some problems with host state. Here are the specs: Nagios v3.4.1 RHEL 6.3 Using NSCA to send results to passive collector Yes, I have 'translate_passive_host_checks' set on the collector. :) So, the system is up and running, and I do see host alerts in /var/log/messages on the collector. However, in the web interface, all hosts remain up. I can go into the host details for a host that's offline because of Sandy, and it reports a host status of UP, with the status information PING CRITICAL - Packet loss 100%. Obviously, the host states coming from the passive monitors are not being translated. Active host and service checks are disabled on the collector, and enabled on the monitors. Passive host and service checks are enabled everywhere, and the collector *is* receiving them. I'd appreciate it if someone can help me out here... I'll provide whatever details are necessary...

Do some rooting around the plugin community (the Nagios Exchange and/or the Monitoring Exchange) to see if you can find some examples of rate-aware plugins. While it's not rate that it's tracking, I know the check_iptraf*.pl plugins will at least keep state between polling cycles, so that might be somewhere to start.

I've some broker modules to handle sql logging and distributed setup. I bet you're using NDOUtils. I wouldn't recommend that. I couldn't keep a Nagios server with under 6000 services limping along when NDOUtils was running. Eventually, the check latencies would go through the roof and the entire server would get farther and farther behind. I went to Livestatus. It took me all of 20 minutes to adjust my reports to use the new interface, and I haven't restart my Nagios daemon since (other than normal maintenance). -- The problem with quotes on the internet is that it's very hard to verify their authenticity. -- Abraham Lincoln -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Nagios-users] does monitoring stop while nagios is flushing queued items?
My installation is centreon + nagios. Sometimes I need to do maintenance on mysql so I stop ndo2db and let nagios cache the result first. And when I start ndo2db, nagios will start flushing the items. I notice from the service perf data file, the data stops coming (or nagios not polling new data) while nagios is flushing queued item. I just want to confirm whether it is the behavior of nagios? If yes, any workaround for this? This is one of the big reasons I stopped using NDOUtils - the broker would regularly block the Nagios process. So yes, you're correct - your NDOUtils broker is blocking, and nothing is happening during these periods of maintenance. That, and the check latency. With NDOUtils, I couldn't let my Nagios daemons run a full week without restarting them or the check latencies would shoot through the roof (that's a full restart, not a reload). -- The problem with quotes on the internet is that it's very hard to verify their authenticity. -- Abraham Lincoln -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Nagios-users] How many hosts and services are you monitoring with Nagios?
What kinds of numbers of hosts and services are you all monitoring?
Which add-ons / distributed frameworks are you using?
At my ${CURRENT_JOB}, I'm monitoring around 600 hosts with just under
6000 services on a single VM running RHEL 5. I do process perfdata
on the same node, and replicate all config data and state data to
a warm standby (also a VM). Replication is done via MySQL replication
(for the config data) and NSCA (for the state data). A custom perl
program dumps the extended state data (disabled notifications,
acknowledgements, etc) for import if needed.
Yes, I know, VM bad. :) Just not bad enough to spend real dollars on
more physical hosts.
This year, I will be bringing up a second pair of monitoring hosts at
a secondary data center, with much the same architecture.

Re: [Nagios-users] Querying nagios object information through command line
Is there a script or a module that can be called through a command line and can retrieve nagios object definition , host , service? I am thinking of calling from php program.

Backup done successfully. All hosts are imported and being monitored, but a few things are not working, like SMS messages and mail messages. Does it need to be backed up from some directory? You need to examine your notification commands. You may have used some third party software to send SMS messages, and that may not be installed on the new system.

Re: [Nagios-users] 2 Nagios boxes running together in different locations
We have a bit of a tempermental firewall at the moment that keeps going down thus resulting in everything appearing down to Nagios in Location A and it alerting like a loonatic for all hosts/services (88/156) You could monitor the firewall, and configure it to be the parent of the hosts behind it. That way, when it goes down, you only get the alert for the firewall crapping out, and not all of the hosts that depend on it. -- The problem with quotes on the internet is that it's very hard to verify their authenticity. -- Abraham Lincoln -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Nagios-users] 2 Nagios boxes running together in different locations
Interesting - How does it work though - I mean if the firewall plays up at Site A, it thinks everything in Site B is down - so Nagios GUI marks everything as down - what happens then if say a server in Site B does actually go down - we will not get alerted to that? That's correct. But, your proposed configuration wouldn't solve this problem - if the firewall fails, the Nagios servers can't contact each other anyway, so they could never agree on what's up and what's down. I made a slight error in my original description - when the firewall goes down it cant contact anything at both locations, not just Site A, due to the fact that the protected interface stays up but just denies all traffic. We are currently working on this with GTA but im losing the will to live with 300 texts virtually every night!! I've dealt with this situation before, and I've ended up implementing two mostly standalone Nagios systems. They each check their own site, so if their external network goes away they are still able to monitor and alert for the things they're responsible for (you have to use out-of-band notifications of course). They also each check each other's *site*, ala the other site's firewall, so the Nagios server at site A can alert and let you know if site B goes away, but it *doesn't* try to alert you for all of the hosts and services at site B. -- The problem with quotes on the internet is that it's very hard to verify their authenticity. -- Abraham Lincoln -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Nagios-users] notifications
I am using Nagios 3.3.1 I have got notifications by SMS working now Is there a way of defining what notifications go to email, what go to SMS and what can go to both. I would like this to apply to escalations as well if possible I create two Nagios contacts for each person at my site, one for email alerts and one for SMS alerts. I then place the appropriate contacts in each contactgroup, according to which type of alert should be sent. Then, for each host/service, I include the appropriate contactgroups. For example, my Exchange servers' CPU services get the exchange-admins-email contactgroup, which only sends email to their contacts. The Exchange servers' database services, however, get the exchange-admins-pagers group, so they get SMS'ed for database problems.

[Nagios-users] Performance data not being written to file with 3.3.1
Hey folks, So, I have the following setup after some re-architecting this past weekend: * Primary Nagios server running 3.2.3 * Secondary Nagios server running 3.3.1, receiving all check results via NSCA Everything should be identical between the primary and secondary servers, other than the secondary system not running active checks and having notifications disabled. Each system should process its own performance data. However, I'm wrestling with the new secondary server... I have it configured to write host and service perfdata to a file, and then npcd processes that perfdata from there. Unfortunately, the host and service perfdata files are being written with no data in them (0 bytes). I'm *getting* the perfdata from the primary host - I can view it in the secondary hosts' web interface. It's there. But for some reason, the secondary Nagios daemon isn't writing that data into the file, but it *is* creating the file. I don't know of any reason this shouldn't work... Does anyone with more knowledge of the nuts-n-bolts know why a passive Nagios daemon (no active checks, all data received via NSCA) wouldn't write the perfdata it receives? It thinks it has data - the host and service perfdata files are created and removed as the Nagios daemon creates them, and the process_* commands process them. I'll provide whatever details are necessary, I just want to verify the basic premise of my setup before flooding you with information. :) Thanks much!

[Nagios-users] Nagios 3.2.3 - 3.3.1 upgrade path
Hey folks, I'm planning a migration to 3.3.1, and I had a quick question for those of you that have done it. I have a manual failover setup, with one monitoring node that sends all results to another warm standby system via NSCA. If I rebuild one system to 3.3.1 and the active monitoring node remains on 3.2.3 for a week or two, are there going to be any issues? I want to be sure they're compatible enough to run for a short time, so I'm not rebuilding my entire environment in an afternoon. Normally, I'd just upgrade the software and go, but I'm taking this opportunity to make some other adjustments to my system, so I'll be doing bare-metal installs from the OS up. I just want to make sure my 3.2.3 system and my 3.3.1 system will be able to talk. :) Thanks much!

Re: [Nagios-users] monitoring dhcp
We've a Windows 2008 server with DHCP role. There is an option to display the statics of the scope. Total Addresses .. In Use .. % Available ..% Is it possible to gt these information available in Nagios. I haven't had much luck with this. Microsoft doesn't expose hardly any of this data via WMI or any other interface that I've found. I haven't looked at Powershell yet, mostly because many of my servers do not have it installed (2003 -vs- 2008). The best I've been able to do is watch the event log for DHCP server complaints about a scope getting close to consumed. Even *that* has been problematic, as the DHCP server service seems to arbitrarily decide when it wants to complain. I ended up writing a custom plugin that watches the event log for those events, parsing the output, and deciding on whether it's appropriate to alert. Benny -- Cats land on their feet.

Re: [Nagios-users] GSM gateway - virtualization ...
I'm running Nagios on OpenSUSE. OpenSUSE is a virtual machine under the Windows 2008 HYPER-V. I'd like to send SMS messages instead of e-mails, because mails can't be delivered in case the SMTP server is down. I don't know any specific hardware for GSM gateway and I have no idea how to use it in virtual environment, how to connect it to RS232? port in the host machine and forward it to the Nagios on the SUSE virtual?? Would anyone be so kind and give me an advice and will share his opinions? We run Nagios servers as virtual machines on mid-sized ESX clusters, so our VMs might end up on any given ESX host at any given time. As a result, I virtualized our serial modem using the IOLAN product from Perle. It is basically a network-to-serial adapter. Our serial USR modem plugins into it, and it plugs into the network. Then, on the Nagios servers (RHEL), the Perle software is installed and creates a serial port that Nagios talks to. That virtual port simply talks to the IOLAN device over the network, and acts as a local serial modem. Now, our Nagios servers can end up anywhere they like, and the modem always stays local as far as Nagios is concerned. It's not infallible, every now and again the two components lose communications, but I check for that via Nagios. There certainly exists the possibility that we could: 1) Lose communications with the virtual modem AND 2) Have a widespread network outage at the same time that would completely clobber notifications, but the chances are pretty minor, and the costs are very reasonable.

Re: [Nagios-users] Scheduled downtime for mass hosts?
Tonight I will be forming maintenance on over 50 of my servers and will be taking firewall and routing links out. I have 86 hosts that this will affect. Im going to put them into scheduled downtime in Nagios. I have my hosts divided into hostgroups. Is there a quick way to schedule all 86 hosts into Nagios downtime rather than having to click on each host in the web GUI and doing them individually? This is precisely why I have a hostgroup that contains *all* my hosts. I just issue a single downtime command for the host*group*, and voila. Benny -- Cats land on their feet.

Re: [Nagios-users] Scheduled downtime for mass hosts?
Ah Benny, I didn't know you could schedule maintenance for each individual host group I have my 86 hosts arranged into 4 hostgroups so I will just do this. 4 clicks and job done, thought I was in for the long haul by clicking all 86 hosts 1 by 1. Thanks, you have saved me a load of time! You can issue commands to both hostgroups and servicegroups... It makes it much easier to deal with outages and scheduled maintenance. And because hosts and services can be in more than one group, you can arrange them however you like according to roles, network placement, or even physical site. :) Benny -- Cats land on their feet.

Re: [Nagios-users] Changing the version of nagios that appears in the e-mail notifications
I would like to change the version that is displayed to reflect that of the release that is currently on the server. What file(s) do I need to modify in order to accomplish this? Your email notifications are just another command, so you need to update the definition of that command. It may be in misccommands.cfg, but really, you're the only one that can answer that one as it could be in *any* of the config files. :) 'grep -r' would be your friend here.

Re: [Nagios-users] Suggestions for checking DHCP Scopes
Does anyone have any suggestions for checking DHCP scopes on Windows servers. I saw one util on Nagios Exchange that uses a vbs script but I have no idea how I would set that up. Define checking DHCP scopes? Do you need to make sure DHCP is running? Do you need to make sure DHCP clients can get addresses? Do you need to check how many IPs are free in the scopes? Each of the above could be a different failure mode. Personally, I gave up on checking for lease availability, we have way too many scopes, VLANs, etc. I now do the following: 1) Check to make sure the DHCP Server service is running 2) Via a custom setup between consol.de's excellent check_logfiles plugin and a perl wrapper I wrote, check for an event 1020 in the system event log and parse the output #2 was a pain, as Windows apparently has no hard-and-fast way to check on IP availability in the scopes, and randomly logs a 1020 whenever it feels you just don't have enough addresses left. With the wrapper program, I parse the 1020 events and apply my own thresholds to determine good, bad, or ugly. Microsoft: why oh why do you not expose the IP address utilization via performance counters or WMI?

Re: [Nagios-users] muti-sessions in Nagios
is there a possbility to ceate multi-sessions in nagios my aim is create many sessions for administrator and i want that an administrator (central) look all the maps but the ohter look just thare maps for example : admin central : in site 0 : supervise all sites admin Nubmer1: in site 1 ; supervise the parc of a thos site 1 admin Nubmer2: in site 2 ; supervise the parc of a thos site and so on If I understand your question correctly, Nagios pretty much does that out-of-the-box. By default, if you use authentication, authenticated users will only be able to see/issue commands to hosts and services for which they are contacts. So, if admin1 is a contact for hosts A, B, and C, while admin2 is a contact for hosts D and E, then admin1 will only see his/her three hosts, and admin2 will only see his/her two.

Re: [Nagios-users] Nagios Issue of not detecting down/up status of server and delay of mails notifications
Is this a valid issue with nagios or is there any way to scale it up. How can a network/sever admin can believe on it if this works like this. This is a configuration issue... I monitor some 700 hosts and 6000+ services on a single host and my notifications go out instantly (once max_check_attempts has been hit). Choose a host that has shown this problem, and grep your Nagios log for it... Copy-n-paste the entries here. That will show what Nagios thinks about the situation.

Re: [Nagios-users] How to monitor specific windows services using nsclient++
Thanks Benny,..but still i couldn't understand is check_nrpe is used for monitoring windows servers because what i know it's for monitoring remote linux servers only.. If yes do i need to install check_nrpe on my Nagios Server.. Also i am already monitoring these basic things but i want to monitor specific services for e.g say mssql running or down..Similarly other important windows services... NSClient++ listens for NRPE requests as well, on TCP port 5666. Hence, if you have NSClient++ installed on your Windows systems, you can use check_nrpe to talk to them. And yes, then you'd need to install the check_nrpe tool on your Nagios server. I prefer using check_nrpe, I only use check_nt for a very small number of services. The command definition I gave you will check a service on a remote Windows server to see if it's running or not. So, open up your Windows services snap-in, and you can check any of the services listed the same way. -- You were doing well until everyone died. -- God, Futurama -- EditLive Enterprise is the world's most technically advanced content authoring tool.

Re: [Nagios-users] Getting Started with Nagios
I then restart the web server, expecting to see a new host inf1 But the host count has not increased and I can't see any reference to the host. I also can not see the new host group I defined. So obviously I am missing something fundamental. Thanks for any incite you care to share :) I then restart the web server... If you mean that literally, as in you restarted Apache, that won't change anything for Nagios. Apache only provides the web server for the UI, it has nothing to do with Nagios. The Nagios daemon is the one you need to restart (or more accurately, you can send it a SIGHUP signal) to pick up on your configuration file changes. Now, if you *did* restart Nagios and your changes aren't appearing in the web interface, do the following: 1) Stop the Nagios daemon 2) Now, go stop the *other* Nagios daemon(s) It is a *very* common problem, especially when people are just starting out, to accidentally start more than one Nagios daemon. Changes are made, *one* of the Nagios daemons are restarted, while the other continues to happily run the old configuration (and show up in the web interface).

Re: [Nagios-users] Default Acknowledge Behavior
Can the default behavior for acknowledging an event be changed. As in can the default be changed from the Sticky Acknowedgement being always checked, to always unchecked? I have read a post on the internet that this is hard coded and you would have to change the source and recompile in order to accomplish this. http://article.gmane.org/gmane.network.nagios.user/54147 This post is very old...maybe this has changed in 3.2.3? This behavior cannot be changed without hacking cgi/cmd.c. It's a simple change: on lines 951 and 977 (this is Nagios 3.2.3), remove the CHECKED from that line. That will make the checkboxes default to *not* checked. I believe this is a much more sane default than checked.

Re: [Nagios-users] Why is check_openmanage so slow on PowerEdge R510?
At one time we had a battery that didn't finish charging for a week, called Dell and got a replacement battery. This was during a regular charge cycle.

I simply got so tired of the charging warnings that I blacklisted the bat_charge totally, but I'd still like to detect that type of error - where the battery never finishes charging.

Re: [Nagios-users] NSClient++. Monitoring the devices behind the Firewall.
The question I have is the same of already reported in the link http://nsclient.com/nscp/discussion/topic/466#-1. The diagram and scenario is the same reported in the link http://nsclient.com/nscp/wiki/doc/usage/nagios/nrpe but with a second remote Firewall. Basically, I know how to configure a remote Windows computer with a fix TCP-IP address but I have no idea how to configure a remote Windows NSClient or an NRPE UNIX client installed behind a remote Firewall. The remote subnet has a NAT in this case and how the Nagios server can reach a remote client in this scenario? Any idea? Well, each of the clients behind the firewall needs to be individually addressable somehow. You can do this in several ways, here are two: 1) Assign ports on the firewall to NAT to the individual clients behind it. Ie, assign port 45000 to be NATed to client 1, port 5666. Assign port 45001 to be NATed to client 2, port 5666, etc. Then, on your Nagios server, use the IP of your firewall and the individual ports to communicate with the clients. 2) Assign multiple IPs to the firewall, and NAT each IP and port X (by default, 5666) to the clients behind it. If you're looking to do this without cooperation from the client and their security folks, you're going to run into problems. If they want you to monitor their hosts, they have to provide some manner of accessing them. In either of the examples above, I would strongly recommend that they assign firewall rules to allow connections to the clients' NSClient++ services *only* from your Nagios server. Don't leave those ports open to the unwashed masses. A VPN between your sites is also an option.

Re: [Nagios-users] NSClient++. Monitoring the devices behind the Firewall.
If you're looking to do this without cooperation from the client and their security folks, you're going to run into problems. If they want you to monitor their hosts, they have to provide some manner of accessing them. Just to be thorough, passive monitoring is also a possibility. In that case, each of the clients would be configured to send the service check results to the Nagios server, and would probably not require any changes to the firewall. However, I choose to use active monitoring, so I cannot help with that setup, nor would I necessarily recommend it.

What external commands are we talking about here? Are we talking about the service commands from the check screen ( disable checks, schedule downtime, etc) . Is is safe to assume that if wwwrun was not in the nagcmd group baaa things will happen in the web console? Not anywhere near my system so I cant try to see what would happen. Any thoughts before I rewrite the central password system to put both a regular user a daemon user in the same file ? What regular user? nagios? Because really, from your description above, both nagios and wwwrun users should be daemon users, so you should be able to have them in the same file and avoid the problem. After all, the nagios user is the one that Nagios daemon will be running as...

Hi Gurus,I have to deploy Nagios plugins on more than 200 Windows servers.

Re: [Nagios-users] Hostgroups: if not contact for one host, none are available
this isn't a bug. by reviewing the source codes, you can find that Nagios(more precisely, the CGIs) just do this way. i have no clue why Nagios won't show partial hostgroups if one has no access to all host members. maybe for performance issue? If this behavior is intention, I'd love to know why... It seems utterly broken to me, and while I have no vote to cast, I'd love to see it changed. While this seems like just a logic thing, I'd have to dig into the code to see if I'm smart enough to come up with a diff. :) Any developers have an opinion/comment?

[Nagios-users] Hostgroups: if not contact for one host, none are available
Hey folks, This has bitten me a few times now, so I figured I'd better report it... If I have hostgroup bob: host1 host2 host3 host4 host5 and contact frank is a contact for hosts 1, 2, 3, and 4 (but NOT 5), frank will not be able to view the *hostgroup*. It gives the usual It appears you do not have permissions ... error. *Surely* this can't be intentional, can it? Why the heck would you _want_ that behavior? I would expect it to display the hosts in the group (viewing a host you're a contact for will show all services, even if you're not a contact for all), or at worst just the members of the group the user is a contact for, but not deny access to the entire hostgroup. In my environment, I have accidentally added a host to the wrong hostgroup. When I do this and the users of the hostgroup aren't contacts for this new one that I misplaced, the users lose access to the entire hostgroup. Am I being dense, or is this a bug? 3.2.3 on RHEL 5.5, BTW. Thanks!

Re: [Nagios-users] Monitoring temperatures on Cisco equipment
I think you misunderstand. Those two plugins return WARNING or CRITICAL if one of the two things occur: 1) If the ciscoEnvMonTemperatureState is not normal. 2) If the passed -w and -c values are less than ciscoEnvMonTemperatureStatusValue. What I'm asking is why #2 is _required_. I can understand it as an optional check if you want to override the device's defaults, but not as mandatory behavior. Cisco devices are smart and know when they're warm or hot. That's the purpose of the ciscoEnvMonTemperatureState. I'm just trying to find out why folks feel that overriding Cisco's defaults is necessary behavior. While I don't have any insider knowledge into *why* it is the way it is, I'll take a guess - most third-party plugins come into existence because they satisfied someone's specific needs. Perhaps the original author needed to further narrow the range of good-vs-bad, who knows? I'd say modify it to your needs. :) Benny (yes, *that* Benny, hi Jeffrey) -- Hairy ape nads.-- Colleen, playing Neverwinter Nights -- Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

Re: [Nagios-users] qpage - OT
It would have been nice to see your qpage.cf file... ;) That seems obvious, see below Be sure you have 'parity=even' in your config. When you run a test with verbose and interactive flags set, do you fail five or six times before you get that message? I've never tried the interactive flag, I will do so. As far as the failures go when I had the retry set to 20 it would to fail 5 times in a row and then reset the modem or something, I can't fully interpret the logs, and then retry again possible 20 times? as in 20 sets of 5. The interactive (-i) option seems to require a page to be sent right now. As of yet I have been unable to get a failure when sending a page manually but I think I've really only sent a small number 10-20 pages manually. The only times it has failed so far is when it's running in daemon mode. Do you guys use USB modems with qpage? These problems got much worse after switching to a USB modem. I didn't notice anything glaringly incorrect with your config... The reason I asked about parity is because I got the exact same error with Verizon and Sprint, except that qpage would decide that the page was not sent (when it had been), so it would retry five times (thereby sending five identical pages). That issue went away when I had a palm-forehead moment and added the 'parity=even' to my config.

Re: [Nagios-users] high latency
Yeah, for giggles I went back further through the archives last night and found stuff back to 2.x series, and not much has seemed to help. I killed some of my mis-behaving active checks, and that dropped to about 20 seconds, then went up to about 35-50. So while that's better, I have A LOT more hosts and service checks to add, and am afraid it'll go nuts when I dump more on. I think I've tried about all the config options I could find and some helped, some didn't seem to, but there should be plenty of horsepower on the machine to run this much faster so not sure why it's not. Hey Dan, I too have been wrestling alligators with service and host check latencies averaging around 60s, and increasing to 100+ (sometimes to 300) after a few reloads during the day. This morning, I enabled the use_large_installation_tweaks option. As of a minute ago, my host check latency is now averaging 2.116s, and service check latency is averaging 0.748s. I didn't see if you had tried this yet, it might be something to consider.

Benny That sounds logical, and this is what I've adjusted: check_command check_local_load!8.0,5.0,4.0!12.0,7.0,6.0 but I've restarted the nagios process and the alert still persists. I dont see anything in nagios.log or /var/log/messages related to this either. what could I be missing? Kill your Nagios daemon. Now, kill the *other* Nagios daemon you have running. If you make changes to your config file and send Nagios a SIGHUP (or restart it) and the changes don't seem to stick, you might have multiple Nagios daemons running, one with an old config (that still thinks 4.00 is a critical threshold), while the new daemon is receiving the changes you mean to make. This is a common issue, and it's easy to fix. Shut down your daemon via whatever method you have (service nagios stop, pkill, etc). Then, wait 30 seconds or so to allow outstanding service checks to wrap up, and see if there are still Nagios processes hanging around. If they are, kill them too. Wait another 30 seconds, rinse and repeat until there are no more Nagios processes. At that point, restart Nagios. Do your changes take affect now?

Re: [Nagios-users] Change Procs Critical threshold
I had another question regarding adjusting these thresholds, this time on
localhost. It regards the Current Load parameter, which is giving me a
Critical Load average of -- 2.47, 3.43, and 4.06
in localhost.cfg, /usr/local/nagios/etc/objects/localhost.cfg, I have this
define service{
use local-service ; Name of
service template to use
host_name localhost
service_description Current Load
check_command
check_local_load!5.0,4.0,3.0!10.0,6.0,4.0
}
which I actually went and adjusted to :
check_command check_local_load!7.0,4.0,3.0!10.0,6.0,4.0
I restarted the Nagios service..but this didn't have any effect -- the
status information still reads the same -- Critical Load Average - 2.47,
3.43, 4.06
From the help for check_load (which I'm assuming you're using
in the command definition):
Usage:check_load [-r] -w WLOAD1,WLOAD5,WLOAD15 -c CLOAD1,CLOAD5,CLOAD15
So, in your service definition, you're telling check_load that you
want to trigger a critical condition if the 15 minute average is 4.0.
Yours is 4.06. So, yes, it's critical. :)
WLOAD1 = 1 minute average warning threshold
WLOAD5 = 5 minute average warning threshold
WLOAD15 = 15 minute average warning threshold
CLOAD1 = 1 minute average critical threshold
CLOAD5 = 5 minute average critical threshold
CLOAD15 = 15 minute average critical threshold
If you want your 15 minute average to *not* trigger a critical, you
need to adjust that last value (4.0) to something higher.

Re: [Nagios-users] Change Procs Critical threshold
I have a couple of systems that are reporting critical notifications, that when you drill into them, the Service : Total Processes has been triggered.

Re: [Nagios-users] host_port objects - Enhancement Request
parent_service is actually a pretty good idea, I hadn't thought of that. I very, very much wish Nagios had the concept of parent_services (notice the plural, no reason not to give a parent service the same multi-parent capabilities as a regular parent host scenario). That way, you could get finer-grained control (it's just the switch port) and deal with multi-homed hosts with that same level of granularity (host A depends on switch 1 port 6 AND switch 2 port 12).

You can also run, if memory serves, the nagiostats command located in your Nagios bin directory to see this information as well.

Re: [Nagios-users] FTP Server is shown alive, but Nagios says DOWN!
The check_command in the *host* definition, not the service definition.
Is this a Windows 2008 FTP server? If so, Win2008 disables pings out
of the box, and a custom rule must be added to the Windows Firewall
to allow ICMP ECHOREQ.
Or use a check_command that would indeed show the correct status of
the host. Do *not* blindly disable the Windows Firewall to fix
this, if this is what's going on.
Benny
Check_command is set to check_ftp and that is shown as UP, can't figure
out
why Nagios is showing ftp server as DOWN!!
Please see the configuration file below.
# Define a service to check host alive the remote machine
define service{
use local-service ; Name of
service template to use
host_name ftpsrv
service_description Check FTP Service
check_command check_ftp!
}
To which service check can we change to, so that Nagios doesn't show an UP
server as DOWN.

Anth.

The host up/down status will be defined by the check_command in the host
definition.
What is this set to ? I would guess that it's been set to check
something that the host doesn't repond to.

Please see the below config, we want to see the free disk space in home

# Define a service to check the disk space of the home partition
define service{
use local-service ; Name
of
service template to use
host_name ftpsrv

check_command check_local_disk!20%!10%!/home

We are using FAN 2.0 NagiosR 3.0.6
Thanks and regards

Re: [Nagios-users] Acquiring data from a log
I need to acquire data from a log, parse if and, if a particular condition is met, notify the problem, otherwise just have on nagios the condition. I.e. if number of record (parsed from log) exceeds 1000, trigger an email, otherwise just have on nagios web page Processed 123 records I have written a script that extracts and parse the data, so I can do inside it Wow. Check out Consul Labs' check_logfiles plugin. Don't re-invent the wheel if you can avoid it. if [ $RESULT = 0 ] then echo No records processed exit 0 elif [ $RESULT -gt $THRESOLD ] then echo CRITICAL: $RESULT records processed exit 2 else echo NORMAL: $RESULT records processed exit 0 fi where RESULT is the result of the computation and $THRESOLD is passed on command line. I have the following questions: 1) How can I see whether the command is run? 2) How can I see which results are passed to nagios? 3) How can I pass both exit values and the string echoed? #3: echo This is output that will show up in the Nagios web UI exit 3 Benny -- Because you have arms like noodles, while I am vigorous and burly. -- Hodgins, Bones -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
