check_disk

[anish]

Hello,

I am using check_nrpe –H localhost –t 30 –c check_disk –a ‘-w 20% -c10%’

Can I exclude paths like /boot etc while using the above

Thanks,
Anish

You should be able to use:

Code: Select all

./check_nrpe –H localhost –t 30 –c check_disk –a ‘-w 20% -c10% -x "/boot"’

From the plugin's usage:

-x, --exclude_device=PATH <STRING>

Code: Select all

[root@SESKLNGCOREPD02 libexec]# ./check_nrpe –H localhost –t 30 –c check_disk –a ‘-w 20% -c10% -x "/boot"’
./check_nrpe: invalid option -- 'x'

NRPE Plugin for Nagios

Version: 2.15
Last Modified: 09-06-2013
License: GPL v2 with exemptions (-l for more info)
SSL/TLS Available: Anonymous DH Mode, OpenSSL 0.9.6 or higher required

Usage: check_nrpe -H <host> [ -b <bindaddr> ] [-4] [-6] [-n] [-u] [-p <port>] [-t <timeout>] [-c <command>] [-a <arglist...>]

Options:
 -n         = Do no use SSL
 -u         = Make socket timeouts return an UNKNOWN state instead of CRITICAL
 <host>     = The address of the host running the NRPE daemon
 <bindaddr> = bind to local address
 -4         = user ipv4 only
 -6         = user ipv6 only
 [port]     = The port on which the daemon is running (default=5666)
 [timeout]  = Number of seconds before connection times out (default=10)
 [command]  = The name of the command that the remote daemon should run
 [arglist]  = Optional arguments that should be passed to the command.  Multiple
              arguments should be separated by a space.  If provided, this must be
              the last option supplied on the command line.

Note:
This plugin requires that you have the NRPE daemon running on the remote host.
You must also have configured the daemon to associate a specific plugin command
with the [command] option you are specifying here.  Upon receipt of the
[command] argument, the NRPE daemon will run the appropriate plugin command and
send the plugin output and return code back to *this* plugin.  This allows you
to execute plugins on remote hosts and 'fake' the results to make Nagios think
the plugin is being run locally.

Try this syntax:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H <host> -t 30 -c check_disk -a '-w 20% -c 10% -x /boot'

Code: Select all

[root@localhost libexec]# ./check_nrpe -H 192.168.67.97 -t 30 -c check_disk -a '-w 20% -c 10% -x /boot'

Many thanks that works.

Can I exclude more than 1?

[mcapra]

Sure! Running off of the previous example:

Code: Select all

[root@localhost libexec]# /usr/local/nagios/libexec/check_nrpe -H 192.168.67.97 -t 30 -c check_disk -a '-w 20% -c 10% -x /boot -x /run -x /sys/fs/cgroup'

Thank you. That works!!

[mcapra]

Awesome! Is it alright if we lock this thread and mark the issue as resolved?

[anish]

Yes please.
