Re: [Nagios-users] Monitoring disk usage
jumping in a bit late on this one... so it sounds like the check itself works on the local box... so if you run from the nagios server ./libexec/check_nrpe -H server -P 5666 -t 10 -c check_root and then... ./libexec/check_nrpe -H server -P 5666 -t 10 -c check_ora could your Nagios server also be connecting to the wrong server... ? I've had DNS issues drive me berserk before. -- Mat W. - http://www.techadre.com Date: Wed, 15 Jul 2009 16:14:27 +0300 From: juki.e...@gmail.com To: guid...@gmail.com CC: nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] Monitoring disk usage Hi Guy, My findings in-line... 2009/7/15 Guy Waugh They should only be defined in one place.

Hi Juki, I'm not a Solaris 10 expert, but... do you have two versions of NRPE configured, one through 'lrc' and one through 'svc'? I don't know what the 'maintenance' entry means, but it doesn't look happy. Any Solaris 10 people out there? Cheers, Guy.

They should only be defined in one place. From those errors, it sounds like
NRPE on the monitored host doesn't have those commands defined, which
suggests that it's not reading your nrpe.cfg config file. I would check out
NRPE on the monitored host... do any checks on that host work at all? Is the
nrpe.cfg file in /usr/local/nagios/etc? Is either the NRPE daemon running or
xinetd is handling the NRPE connections? Is the host listening on port 5666?
Are the permissions on the nrpe.cfg file correct? What happens when you run
an NRPE service check for that host manually, from the nagios server?
If none of that give you any joy, post the nrpe.cfg file to this list if you
like, suitably obfuscated of course.

Guy.

Re: [Nagios-users] Monitoring disk usage
Hi Guy,
I tried all the changes as per your suggestion, however, I still come up
with the same errors as before, that is;
"NRPE: Command 'check_ora' not defined"
"NRPE: Command 'check_server1' not defined"
"NRPE: Command 'check_var' not defined"
Where else in the configuration files on the monitoring server are commands
defined?

Juki

You're still half way between the two approaches with your service
definitions, because you're passing arguments :-)
Try this instead:
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description Root Partition
check_command check_nrpe!check_root
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description var Partition
check_command check_nrpe!check_var
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description server1 Partition
check_command check_nrpe!check_server1
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description ora Partition
check_command check_nrpe!check_ora
}

Try my changes suggested above and see if these errors persist. They might
be happening because you're passing arguments to the remote NRPE daemon, I'm
not sure...

Re: [Nagios-users] Monitoring disk usage
Hi Guy,
Many thanks for your post.
I decided to go with Option (1) as per your description and did the
following in the nrpe.cfg file on the monitored host:
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 30% -c 20% -p /
command[check_var]=/usr/local/nagios/libexec/check_disk -w 30% -c 20% -p
/var
command[check_server1]=/usr/local/nagios/libexec/check_disk -w 30% -c 20% -p
/var/opt/BGw/Server1
command[check_ora]=/usr/local/nagios/libexec/check_disk -w 30% -c 20% -p
/var/opt/mediation/ora
And then on the nagios monitoring server I have this:
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description Root Partition
check_command check_nrpe!check_disk!15%!10%!
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description var Partition
check_command check_nrpe!check_var!30%!20%!
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description server1 Partition
check_command check_nrpe!check_server1!30%!20%!
}
define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description ora Partition
check_command check_nrpe!check_ora!30%!20%!
}
When I log into the nagios Web GUI, the services for the ora, server1 and
var partition have been successfully created. However, looking at the
"status information" column, I have the following errors:
"NRPE: Command 'check_ora' not defined"
"NRPE: Command 'check_server1' not defined"
"NRPE: Command 'check_var' not defined"
This indicates that I need to explicitly define 'check_ora', 'check_server1'
and 'check_var' elsewhere. So, where else must I define these services so as
to clear out the errors above?
Thanks in advance!

Re: [Nagios-users] Monitoring disk usage
Hi Juki,
As I understand it, you can either (1) 'hard-code' your NRPE checks in the
nrpe.cfg file on the monitored host (so that the checks are explicitly
defined), or (2) set up NRPE on the monitored host in such a way that you
can pass arguments in your NRPE checks. It looks like you're landing
somewhere between the two with your configuration.
I would either go the Option (1) way, having something like this in your
nrpe.cfg file on the monitored host:
*command[check_root]=/usr/local/nagios/libexec/check_disk -w 30% -c 15% -p /
**command[check_var]=/usr/local/nagios/libexec/check_disk -w 30% -c 15%** -p
/var
**command[check_server1]=/usr/local/nagios/libexec/check_disk -w 30% -c 15%*
* -p /var/opt/BGw/Server1
**command[check_ora]=/usr/local/nagios/libexec/check_disk -w 30% -c 15%** -p
/var/opt/mediation/ora*
, and then having services on the nagios host like this:
*define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description Root Partition
check_command check_nrpe!check_root
}*
Alternatively, for the Option (2) method, on the monitored host, in
nrpe.cfg:
*command[check_disk]=/usr/local/nagios/libexec/check_disk -w $ARG1$ -c
$ARG2$ -p $ARG3$*
, and a service example on the nagios host:
*define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description Root Partition
check_command check_nrpe!check_disk!30!15!/
}*
I may not have the syntax in the 'check_command' of that last service
exactly right, but that's the general idea.
To go down the Option 2 road, you have to have configured the NRPE daemon on
the monitored host with '--enable-command-args', and have to have a line in
your nrpe.cfg file that says 'dont_blame_nrpe=1'. This is because allowing
command arguments in this fashion can be a security risk. The default
nrpe.cfg file has some comments that refer to this.
HTH,
Guy.

Re: [Nagios-users] Monitoring disk usage
Hello again,
Thanks for the tips so far. Now some responses;
On the monitored host, I have setup nrpe.cfg and therein I have set the
option "allowed_hosts=" and also revised the format
as shown below;
*#specific commands#
command[check_disk]=/usr/local/nagios/libexec/check_disk -w 30% -c 15% -p /
-p /var -p /var/opt/BGw/Server1 -p /var/opt/mediation/ora
command[check_swap]= /usr/local/nagios/libexec/check_swap -a -w 10% -c 5%
command[check_procs]=/usr/local/nagios/libexec/check_procs -w 300 -c 400
command[check_ssh]=/usr/local/nagios/libexec/check_ssh -4 -t 10 -p 22
localhost
command[check_ftp]=/usr/local/nagios/libexec/check_ftp -t 5
*Then on the monitoring server, I have also setup the monitored host file
(host.cfg) with the service description as follows;
*define service{
use generic-service ; Name of
service template to use
host_name emm4
service_description Root Partition
check_command check_nrpe!check_disk!15%!10%!
}*
*
*After setting up all this, I refreshed the nrpe client on the monitored
host and also restarted the nagios service on the monitoring server, this is
after I checked that there were no errors whatsoever in the nagios
configuration files. And yes, I logged into the monitored host as the nagios
user and was able to verify that the check_nrpe command definition does run
successfully.
When I log into the nagios web GUI, I'm able to see the alerts, warnings and
details for the check_swap, check_procs, check_ssh and for check_ftp. For
the case of check_disk, I only see alerts/warnings and details only for the
root (/) partition and NOT those for the /var, /var/opt/BGw/Server,
/var/opt/mediation/ora.
This is despite the fact that these partitions are defined in the nrpe.cfg
file on the monitored host as shown above.
This is still puzzling*

You haven't mentioned anything about configuring Nagios to run a check against the service you've set up on NRPE. Have you done that part yet?

Did you add a service on the main nagios host to call the nrpe command
you just set up? i.e.,
define service {
service_description Check remote disk space
host_name the_remote_host
check_command check_nrpe!check_disk
}

You cannot have two definitions with the same [name], they must be
unique.

When reporting problems, please report what you _do_ see. It's often
much more useful than what you _don't_ see. "I went to drive to work
this morning but didn't see my car" isn't very informative but
"Instead, I saw a giant ball of fire in the shape of a car" is much
more helpful. Also include the full, complete host{} and service{}
definitions for the problem service. You can get them from
objects.cache if you don't want to expand templates you may be using
yourself.

a) Never test plugins as root. Nagios doesn't run them as 'root' and
you're likely to see permissions differences that send you down the
completely wrong troubleshooting path.
b) When testing something like this, verify you can run your
check_nrpe command definition successfully for this check, from the
nagios machine, as the nagios user.

[Nagios-users] Monitoring disk usage

By either using check_by_ssh or with a remote agent like NRPE.
The check_by_ssh method looks something like this:
define command {
command_namecheck_disk_remote
command_line$USER1$/check_by_ssh -H $HOSTADDRESS$ -C
"$USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$"
}
The documentation for check_by_ssh and check_disk should fill in the
blanks as to what's happening there.
