Re: [Nagios-users] pnp4nagios - Hostname not set
Hi,
Ok, good shout.
I've install the latest version.
The config check page looks ok but I'm getting errors where is isn't any rrd
data yet.
How long does it take to start producing this data when in sync mode?
Can I force it along quicker so that I know everything working?
Thanks again

Hi guys,
I've followed the install instruction from here
(http://docs.pnp4nagios.org/pnp-0.4/install) to install pnp4nagios v4 on my
nagios 3.x running on a fedora 14 box but I'm stuck when verifying the install.
any specific reason not to use 0.6.x ?
When I do http://servername/Nagios/pnp my first error is 'Hostname is not set'
followed by 'perfdata folder is empty' and 'no rrd files'
I've looked and sure enough there are no rrd files in the folder, plus there is
no entry in the log file.
To me this suggests that Nagios isn't firing the command
'process-service-perfdata' after completing a check.
My commands.cfg file looks correct;
# Added by Tristan for PNP 4 Nagios
define command {
command_nameprocess-service-perfdata
command_line/usr/local/nagios/libexec/process_perfdata.pl
}
define command {
command_nameprocess-host-perfdata
command_line/usr/local/nagios/libexec/process_perfdata.pl -d
HOSTPERFDATA
}
And so is my Nagios.cfg file;
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
these tow are the only things I've changed from the default install.
Any ideas what I've missed??
Any tips on how I can drill down further to see what's not happing and why?
Thanks in advance :)

Re: [Nagios-users] distributed host checks: freshness checking issues
As good as Merlin sounds, we currently have something that works (including user-friendly managment provisioning scripts) and unfortunately way too much other things on our plate to invest the appropriate amount of time in this. But I'm certain that I will revisit these ideas in the future, so thanks a lot for all your suggestions! Much appreciated.

That the master will *always* keep on doing *some* host checks no matter what you configure? More or less, yes. It will at least schedule them even if it gets results for them, but eventbroker modules can block even forced host checks. I'd look into using Merlin, DNX or mod_gearman if I were you. It will do what you want with far better performance than NSCA will ever be able to. Thank you for the confirmation and the tips! I've done some quick reading on Merlin, DNX and mod_gearman, and while they look very interesting, our Nagios setup is probably a little too complex to distribute the checks automatically the way we're doing it now. I doubt it. The largest setup running mod_gearman is checking something like 35000 services. The largest merlin install is running close to 48000. I'm sorry to say I have no figures for DNX. We have Nagios slaves (workers) in multiple, independent locations, and we're exploiting that to the fullest by running different service checks of the same host from different locations: checks for public services are effectively checked from a remote location, while NRPE checks to the same host are done from within the same datacenter. The configs for each master slave are generated from the same host/service database. For this you'd have to use two host definitions if you use Merlin, since checks are split to workers based on hostgroup affiliation. Apart from that, everything should work just fine. Apparently, send_gearman can be used as a send_nsca replacement, which I'll have to check up on later. It would be cool if it can send multi-line output and performance data. NSCA cannot do multi-line and doesn't seem 100% reliable either. I'm fairly sure it can, but submitting passive checkresults with multiline output is not very well tested and may not work well with Nagios core. It will be particularly problematic if the check output is larger than 4096 bytes, since that's the size of the command pipe. It works flawlessly with Merlin though, as does external command forwarding and a lot of other nifty things that NSCA-based setups simply doesn't handle. -- EditLive Enterprise is the world's most technically advanced content authoring tool.

We live and we learn. Now it's time for me to learn how much wine I can drink on a friday night without passing out. I'm looking forward to that particular experiment.

Hey everyone,
First, I'm new, so please be gentle :)
I have made some recent modifications to our nagios3 files. In
resource.cfg I added the following macros: $db_name$, $db_user_name$,
and $db_user_pass$. These seem to be ok.
I added a service like this:
define service {
hostgroup_name mysql-servers
service_description Mysql FSRW
check_command check_mysql_FSRW
use generic-service
notification_interval 0
}
And finally I added a command like this:
define command {
command_name check_mysql_FSRW
command_line $USER1$/check_mysql_query -q SELECT
COUNT(*) FROM
entry WHERE periodDATE_SUB(now(),INTERVAL 2 DAY) AND status_code2
AND retries=0 AND type=0 -w0:0 -c10 -H $HOSTADDRESS$ -P 3306 -d
$db_name$ -u $db_user_name$ -p $db_user_pass$
}
When I have nagios validate everything, it gives no errors. I then
restart nagios for the config to take effect, and it comes up. In the
event log I see some issues with the service (it appears to be trying
to connect to the mysql servers as user nagios, not the specified
user). When I then log back into the server and look at my
services.cfg file, and my commands.cfg file, the entries I added to
both of them have been removed - like they were never there.
Then perhaps you forgot to save, or someone undid your changes from a
backup, or some other kind of pilot error happened. It's most certainly
not Nagios' fault though, so you're asking in the wrong forum.
So, I guess I have a few questions.
First, are those entries in the resource.cfg file ok? Does nagios
support the underscores and longer names? Its easier to understand at
a glance than $USER3$ $USER4$ and $USER5$.
Second, does the command_line look ok? I'm trying to figure out why it
isn't using the username and password I'm passing to it.
Not yet, no. It will some day though.
Finally, why do the command and service keep disappearing out of my
config file? It's making it a pain to troubleshoot.
Because someone is removing them, or you're forgetting to save them.
Things don't just remove themselves.
Any suggestions or advice would be greatly appreciated.
Ask around if anyone's altering the configuration besides you. Files
really don't just alter themselves. Trust me on this.

Dual-stack environments are about to become the norm, not an edge case, and it would be wise for Nagios to be able to support that, properly detecting when a host is down based on all interfaces being unreachable.

Arguably, either is correct and Nagios is doing one of two right things. I'm not sure. If a test times out and Nagios tries again 10 seconds later instead of the 60 seconds specified, that could cause problems; load related problems when you have many of these tests running and timing out and problems for the system under test not having sufficient time to recover before the next check is done. True, but *if* someone has the latter kind of problem, I'd expect him to keep it in mind while writing the configuration, too. IIRC, the actual code adds check_interval/retry_interval to the variable that holds the (previous) scheduled check time - i.e., the time when the previous check supposedly was *started* (assuming negligible check latency). Configuring a retry_interval of one minute for a service whose sustained request rate may be *less* than one per minute sounds dubitable to me. (And I'm a firm nonbeliever in Unix-ish load figures, as opposed to actual CPU usage etc., but that's a different rant.) Kind regards, J. Bern Thanks for this explanation. It helps quite a bit. The checks we run normally take 5 - 15 seconds to complete, but we allow a much longer value for timeout. I was under the impression that the retry interval was only counted from the time the previous check completes and the status (which is needed to determine if a retry is necessary) is known. Why is the retry time determined before it's know that one is needed? It looks like checks that have longer timeouts need to have longer retry intervals to compensate for the worst case. That's not intuitive to me, but I can live with it. Paul Dubuc -- EditLive Enterprise is the world's most technically advanced content authoring tool.

[Nagios-users] How to scale the performance of nagios
Hello Friends, I have just implemented this nagios-3.2.3 solution to monitor a large client infrastructure, i have to monitor say around 200 network switches for around 20 services in each switch and some linux servers around 10 services, and many windows servers with around 6 services to monitor. I have put the configuration for all these in the various config files of nagios like switch.cfg for switches, localhost.cfg for linux servers, windows.cfg for windows servers. So infact the config files have grown very large in size. I have a single stand alone implementation of nagios server i.e single nagios server monitoring entire IT infrastructure of the client(not the distributed one). I want to know this thing that, is it very normal for the standalone implementation of nagios to monitor the size of infrastructure that i have mentioned quite efficiently without any delay in the alerts and notifications. Since i am monitoring very critical network elements any delay in the host/service failure notification will harm us. What i have observed is that nagios has become slow in sending notifications and there is delay in sending a notification on actual failure of a critical host/service. Is nagios is not very fast in doing the service checks for all these around 300 hosts and 300*15 approx. services very fastly, efficiently and reliably. It is a very worst thing that a critical network element/service has got down now and we are getting the notification for the same after a delay of say 5 minutes. How to scale the performance of my implementation of nagios(on fedora 14) so that it should be reliable. What is the difference between active checks and passive checks. will it be useful to enable passive checks for all these instead of active check to increase the performance and will it be reliable. if yes how we can enable the same.

[Nagios-users] added host not appearing in web interface
Hi there -- We are running Nagios 3.1.2 with the NRPE 2.12 client on our systems. We recently installed the VirtualBox application on one of our monitored systems, and have Ubuntu 10.04 LTS 64-bit as the guest operating system. We want to monitor the disk usage, processes, mysql server, and rsyslogd daemon on the virtual machine, so the NRPE client was installed and configured to start on system boot. After that was done, the appropriate changes were made to the various config files on the Nagios server. The virtual machine and Nagios server were rebooted, in that order, after the changes were made. When going through the web interface on the Nagios server, the virtual host does not appear listed in any of the pages. I confirmed the nrpe daemon was operational on the client, and also verified that port 5666 was open, and the firewall on the client was deactivated. The nrpe daemon is run via the /etc/rc.local file using the following command syntax: /usr/local/nrpe/bin/nrpe -n -c /usr/local/nrpe/etc/nrpe.cfg -d I checked the Nagios server, and confirmed the virtual host was listed in the /etc/hosts as well as the nagios configuration files. The nslookup command, run on server and client, confirmed the presence of the virtual host in the DNS database. What would cause the client not to appear in the Nagios web interface, and how can I correct it? Thanks. The information in this e-mail is intended only for the person to whom it is addressed.

got free memory.
However, the issue with check_memcached is that it's looking at the
hits/misses ratio since start up of the memcached-process.
Whereas I need to know if a sudden increase in misses instead between
polls has occured.
Is anyone familiar with a such check for Nagios?
Best regards,
