NagiosXI localhost check_disk getting errors with ARGS

[akepley]

Starting seeing localhost check_disk only having issues. All other services are returning just fine. Turned on dont_blame_nrpe =1 and ran from command line. Below is an example of both localhost and remote host:

Code: Select all

[email protected] libexec$ ./check_nrpe -H 127.0.0.1 -t 30 -c check_disk -a '-w 20% -c 10% -p /'
DISK CRITICAL - 20% is not accessible: No such file or directory
[email protected] libexec$ ./check_nrpe -H info01.ec2.prod.azw.nasba -t 30 -c check_disk -a '-w 20% -c 10% -p /'
DISK OK - free space: / 5085 MB (53% inode=87%);| /=4352MB;7960;8955;0;9950
[email protected] libexec$ ./check_nrpe -H 127.0.0.1
NRPE v2.15

From the local Nagios XI machine, can you share the output of:

Code: Select all

/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
ls -al /
df -h

You run the following command locally, on the Nagios XI server:

Code: Select all

[email protected] libexec$ ./check_nrpe -H 127.0.0.1 -t 30 -c check_disk -a '-w 20% -c 10% -p /'

and the following command against the client (remote box):

Code: Select all

[email protected] libexec$ ./check_nrpe -H info01.ec2.prod.azw.nasba -t 30 -c check_disk -a '-w 20% -c 10% -p /'

Is the "check_disk" command defined the same way on both machines?

Note: You will find the command's definition in the "/usr/local/nagios/etc/nrpe/common.cfg" or in the "/usr/local/nagios/etc/nrpe.cfg" file.

[akepley]

Ok, remote client had a nrpe directory with common.cfg as well as the nrpe.cfg under etc.
NagiosXI server only had nrpe.cfg under etc.

The check_disk command on the remote client in common.cfg fixed the issue with NagiosXI server config:

Code: Select all

command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$

Was there anything else we can help with or can we lock the thread?

[akepley]

I suppose we can lock it. I'm confused why the NagiosXI server itself was missing this file if it needed it though. Will I run into other command issues?

[lmiltchev]

The check_nrpe plugin is usually used to monitor remote machines, not the local Nagios XI server. The "common.cfg" is installed only when you run our official Linux agent installer script, which is normally run on remote boxes. The commands defined in this config are used by the Linux server wizard that ships with XI. I hope this makes sense.

I will be closing this topic now. If you have any more questions/issues, please start a new thread. Thank you!
