Nagios Support Forum

Hello

Is there a way to have a monitoring wizard to monitor a Solaris 10 box as we do for a Windows server?
NRPE is installed on the solaris box and we would like to monitor disk space, running services / processes...

Thanks

Chris

Probably, although we've only just started trying to work with Solaris. There's a decent chance that the Linux wizard ( http://exchange.nagios.org/directory/Ad ... rd/details ) will also work with Solaris (at least mostly), so what I would suggest is giving that a shot and letting us know what does or doesn't work.

I will then try to use the Linux template and let you know.

Thanks

Chris

Hello

So I downloaded the wizard for Linux. I first try to install the agent on a linux machine, then use this wizard to monitor the linux box. Everything is working well to monitor this linux box.
So I installed NRPE on the Solaris box according to this procedure: http://www.askarali.org/nrpe_solaris10.html
I modified the nrpe.cfg file and put our Nagios server IP address: allowed_hosts=192.168.1.10

I tried to use the linux wizard but each monitored items, except ping, give the following error message:
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages

When I try to run the command manually:
# ./check_nrpe -H 192.168.1.26 -t 30 -n -c check_disk -a '-w 20% -c 10% -p /u01'
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

I try with and without -n in the command.
Also try the following without success:
# /usr/local/nagios/bin/nrpe -n -c /usr/local/nagios/etc/nrpe.cfg -d

Any help will be appreciated to monitor a Solaris box with Nagios xi (Disk space, CPU, Memory, processes, Oracle...)

Best Regards

Chris

The wizard also requires that the following option be set in addition to allowed_hosts:

dont_blame_nrpe = 1

Thanks for this information.
So I changed this parameter in the nrpe,cfg file and restarted the nrpe service.

Now the previous error message has disappeared, but I have new ones:

For most of the commands (check_disk, check_cpu_stats, check_swap, check_procs, check_open_files, check_mem, check_open_files, check_init_service) it returns the following error:
NRPE: Command 'check_disk' not defined

Only three monitored parameters are OK: Load, Ping and Users.

Any idea on how to proceed to monitor all failed checks?

Thanks

Chris

These definitions can be found in one of the files shipped with the Agent tarball:

linux-nrpe-agent/subcomponents/nrpe/mods/cfg/nrpe/common.cfg

Place that in /etc/nagios/nrpe.d/ (or whatever is appropriate for Solaris - probably the same), restart NRPE, and your checks should work.

Hello

With your help and a few articles on the Internet, I finally managed to monitor my Solaris server.
So, I have copied the common.cfg file to a new directory (I created /opt/csw/etc/nrpe), gave permission to user nagios on this directory and file.
Then I needed to edit this file and put the right path for each scripts. I my case it was /opt/csw/libexec/nagios-plugins/<scriptname>
Some scripts for Linux are not available on Solaris so I just commented out the script in the common.cfg and have added those made for Solaris (scripts installed with the nrpe plugin and those downloaded and manually copied).

I aslo needed to edit the services from the Nagios interface and changed the name of the service ($ARG1) and in some cases, the $ARG2 line also according to the plugin.

Many thanks again for your help

Chris

Thanks qc for posting your steps for this. I'm sure you're not the last person who will need to do this, and it helps us out a lot for future references.
