The problem I see with this move is that, if something temporarily hampers an nsca communication (e.g. transient high load, or temporary network blip), then there's no guaranteed way for nagios to know the real state of the service on the next check cycle. I wonder if anyone out there has implemented their checks similar to this, and what solutions or workarounds were implemented to make sure that nagios will eventually get updated with the correct states. You want freshness checks. Browse the nagios documentation for it and you'll find what you're looking for. Welcome to the list btw. It seems things finally worked out for you. But freshness checks imply that checks should be coming in at a regular interval (unless I'm mistaken). In this case, I don't have an idea when the next check result will come as I'm only sending results on state changes. Ah, right. In that case, check out Merlin. It replaces NSCA with a much faster protocol for transmitting check-data, and you get failover for free in case the poller node goes to lunch. http://www.op5.org/community/plugin-inventory/op5-projects/merlin -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Beautiful is writing same markup.

[Nagios-users] Some alerts not getting to sendmail
Good morning, or whatever as the case may be...
I have a Nagios 3.2.1install which is showing a problem I'm unsure how
to troubleshoot further. It's either something simple I'm missing, or a
deeper, more difficult problem. Or a transient to be perhaps put on a
shelf until it happens again.
First, the questions:
- Is the notifications log absolute?
- Meaning, if a notification is shown in this log, it has passed all
filters (notification options etc) and Nagios believes it was submitted
to the MTA.
- Is there anywhere besides the MTA's log,status.dat and nagios.log to
look for clues to mail problems?
==
Details
- Running on FreeBSD 7.0, using stock sendmail on localhost.
- In general, everything is working fine. 125 hosts, 1600 ish services.
This system has been up and stable for a few months.
Host and service notifications of all kinds go out properly all the time.
Last night, I had a host go down. Notification got to my cell phone and
the other contacts it's configured to just fine. This morning, I dealt
with the problem host and Nagios showed it back up. But no Host up
notification to any of the configured contacts. The Notifications log
shows the host up notifications as having been sent. There's nothing in
/var/log/maillog for the time Nagios says the notifications were sent.
In status.dat, the record for my cell contact has a
last_host_notification line with the epoch time version of the exact
second the notification was in theory sent. Host and template records
included at the bottom of this email. I've included one contact def, but
there were 4 contacts, using 2 different scripts that should have
received the notification.
As far as I can see, there is nothing in the host configuration or
related templates that would keep a host up notification from being sent.
We use custom host-notify scripts which log actions, and again, no
entries for the specific problem, but lots of other notifications before
and after. These scripts could be the problem, but I want to rule out
other issues first.
Thank you for your time,
Tim Palmer

[Nagios-users] More than one command defined
Hi,
I have a need to run two different commands when processing the performance
data from Nagios (3.2.2)
I want the first command to run the process-perfdata.pl script from
pnp4nagios and the second command to log various things to a different log
file.
The reason is that we've only just had a requirement to process performance
data for pnp4nagios graphing. But historically we've created our own
performance data log
which is then used within a database to produce SLA reports developed
in-house (no graphing just numbers produced for the SLA reports)
If I do the following I don't get an errors when I run nagios -v nagios.cfg
... :-
define command {
command_name process-service-perfdata-file
command_line first command - process performance data for
pnp4nagios
command_line second command - log different data to a different
file
}
I'd like to avoid creating a script with both commands in if I can help it
as it's extremely useful to keep it simple and visible in the
misccommands.cfg file.
Perhaps there is some other way I can do this or is a script with both
commands really the only way ?
Any help / pointers would be really appreciated. If I'm being dense about
this and the answer is staring right at me feel free to say so!
Thanks,
Deborah

You could use Merlin and set the perfdata_table option in the database
section of the daemon compound. Then you can grab the perfdata items
from the merlin database. Note that you'll have to drop old entries
from that table every once in a while though, as the table will surely
grow huge otherwise.
That doesn't really let you have things visible in the misccommands.cfg
file though, so you'll have to pick your poison on this one.

Re: [Nagios-users] More than one command defined
I'm looking at the same issue and our thoughts are to use NDO utils or
possibly custom NEB to grab perf data that way, but then still let
pnp4nagios run the 'normal' way.

[Nagios-users] SNMP checks, using multiple snmpgets
Hi, Im trying to get my SNMP monitoring a bit more informative. I want to monitor port status on ethernet switches (which Ive tested and works quite nicely). Im using the instructions given here: http://www.thegeekstuff.com/2008/11/how-to-monitor-network-switch-and-ports-using-nagios/ What would be nice is that in the out put of a give port, rather than just saying up or down Id like to also include the output from the ifDescr along with the port status. Logically this would seem to be possible, give the how to above shows in example 7 a config whereby you monitor multiple ports in a single command. I tried this config: check_command check_snmp!-C public -o ifDescr.52 -m RFC1213-MI B -o ifOperStatus.52 -r 1 -m RFC1213-MIB The output of the command is fine, I see the string returned from the ifDescr first then the status of the port, but Nagios takes this as being an error state and marks the service as faulted permanently. If anyone can understand that, do you know if what I want is possible to achieve? :P thanks! Andy. -- Beautiful is writing same markup.

I have a Nagios 3.2.1install which is showing a problem I'm unsure how to troubleshoot further. It's either something simple I'm missing, or a deeper, more difficult problem. Or a transient to be perhaps put on a shelf until it happens again. First, the questions: - Is the notifications log absolute? - Meaning, if a notification is shown in this log, it has passed all filters (notification options etc) and Nagios believes it was submitted to the MTA. Yes. Excellent, thank you. That's the critical bit for me regarding Nagios. - Is there anywhere besides the MTA's log,status.dat and nagios.log to look for clues to mail problems? The receiving end comes to mind, or any server(s) in between. == Details - Running on FreeBSD 7.0, using stock sendmail on localhost. - In general, everything is working fine. 125 hosts, 1600 ish services. This system has been up and stable for a few months. Host and service notifications of all kinds go out properly all the time. Last night, I had a host go down. Notification got to my cell phone and the other contacts it's configured to just fine. This morning, I dealt with the problem host and Nagios showed it back up. But no Host up notification to any of the configured contacts. The Notifications log shows the host up notifications as having been sent. There's nothing in /var/log/maillog for the time Nagios says the notifications were sent. In status.dat, the record for my cell contact has a last_host_notification line with the epoch time version of the exact second the notification was in theory sent. Host and template records included at the bottom of this email. I've included one contact def, but there were 4 contacts, using 2 different scripts that should have received the notification. As far as I can see, there is nothing in the host configuration or related templates that would keep a host up notification from being sent. We use custom host-notify scripts which log actions, and again, no entries for the specific problem, but lots of other notifications before and after. These scripts could be the problem, but I want to rule out other issues first. Notifications are a pretty integral part to what makes Nagios worth anything at all. Since you're using homebrewed scripts and noone else has reported any problems with them, I suggest you first debug your own scripts, or enable debug-logging for notifications. The dosc will tell you how to do that. It won't help for this occurrance of the failed notifications, but it will definitely help you in the future if it ever happens again. Agreed on all counts. Now that you've confirmed the final-ness of the notifications log, I am comfortable looking outside Nagios to the scripts, system and sendmail. I'm sure there's a reasonable, logical explanation for a small subset of mail not getting from Nagios to the local MTA... Thank you Tim Note to self, and whoever else might be listening - properly quoting plugin output before releasing into the shell is a Good Thing. Blaming ex-employees for the oversight is tempting, but cowardly. And Tim's Trouble Shooting Rule #1 holds again - It's your fault, find what you did wrong or, Never forget you're an idiot.

Re: [Nagios-users] More than one command defined
Thanks for the input everyone. Much appreciated.
I'll try with merlin and see where that goes. And the script idea as well.
The trouble is Nagios is a complicated beast (to me anyway). Coupled with
that and getting pnp4nagios working as well this week, my head hurts from
config file overload :)
Anyway all food for thought!
Thanks again.

Hi,
I have a need to run two different commands when processing the
performance
data from Nagios (3.2.2)
I want the first command to run the process-perfdata.pl script from
pnp4nagios and the second command to log various things to a different log
file.
The reason is that we've only just had a requirement to process
performance
data for pnp4nagios graphing. But historically we've created our own
performance data log
which is then used within a database to produce SLA reports developed
in-house (no graphing just numbers produced for the SLA reports)
If I do the following I don't get an errors when I run nagios -v
nagios.cfg
... :-
define command {
command_name process-service-perfdata-file
command_linefirst command - process performance data for
pnp4nagios
command_linesecond command - log different data to a different
file
}
I'm not surprised. This is a sort of unintentional fallout that comes from
using the template system the way it's defined today. I guess only the
second command_line will get run though, right?
I'd like to avoid creating a script with both commands in if I can help it
as it's extremely useful to keep it simple and visible in the
misccommands.cfg file.
Perhaps there is some other way I can do this or is a script with both
commands really the only way ?
You could use Merlin and set the perfdata_table option in the database
section of the daemon compound. Then you can grab the perfdata items
from the merlin database. Note that you'll have to drop old entries
from that table every once in a while though, as the table will surely
grow huge otherwise.
That doesn't really let you have things visible in the misccommands.cfg
file though, so you'll have to pick your poison on this one.

Re: [Nagios-users] server profiling options and pre-caching macros
Watching nagios in debug mode for awhile, made me think about the processing of macros and the performance impact. It seems that for most macro's, like user defined ones, they don't change. So does it really make sense to keep processing them over and over and over...could that be something that maybe you could do in the pre-cache stage when nagios starts. Would that cause more problems?
