You need to remove the .sh from the end of the command.
Edit the $ARG1$ and change

check_cpu_stats.sh

to

Code: Select all

check_cpu_stats

Save it out and apply the config and it should work for you.

Hi..
I have made the changes advised, but still facing the same issue.

here is the output from the remote server.
Updated the config file in remote server, restarted the services.
command[check_cpu_stats]=/usr/local/nagios/libexec/check_cpu_stats $ARG1$ $ARG2$

service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]

output on running the script:
CPU STATISTICS OK: user=0.20% system=0.30% iowait=0.00% idle=99.50% | user=0.20% system=0.30% iowait=0.00%;80;90 idle=99.50%

Output from Nagios XI portal:

COMMAND: /usr/local/nagios/libexec/check_nrpe -H uusrcpmwik00 -t 30 -c check_cpu_stats -a '-w 85 -c 95'
OUTPUT: NRPE: Command 'check_cpu_stats' not defined

Could you please upload the check_cpu_stats for me, so that will add this and will give a try.

You shouldn't have edited the command on the remote server.
Edit the common.cfg file and change it back from

Code: Select all

command[check_cpu_stats]=/usr/local/nagios/libexec/check_cpu_stats $ARG1$ $ARG2$

to

Code: Select all

command[check_cpu_stats]=/usr/local/nagios/libexec/check_cpu_stats.sh $ARG1$ $ARG2$

Save it and restart xinetd

I have both the files in the path,so it should have picked any of the files.

[root@uusrcpmwik00 libexec]# ls -ltr | grep -i check_cpu_stats

-rwxr-xr-x. 1 root root 5355 Aug 5 11:33 check_cpu_stats

Output from remote server, seems like issue with the script, I have downloaded the script from Nagios site.

It seems like this issue has been fixed in a newer version of the plugin. You can download the revision 2.1.1 from here:

https://exchange.nagios.org/directory/P ... ed/details

Example:

Code: Select all

[root@speedking libexec]# ./check_cpu_stats.sh
CPU STATISTICS OK : user=0.50% system=0.50% iowait=0.00% idle=98.99% nice=0.00% steal=0.00% | CpuUser=0.50;CpuSystem=0.50;CpuIoWait=0.00;CpuIdle=98.99;CpuNice=0.00;CpuSteal=0.00;30;100

Let me know if this helped.

Hi...

I have replaced the file with the updated one and I tried from remote server, it is executing perfectly.
./check_cpu_stats
CPU STATISTICS OK : user=0.00% system=0.50% iowait=0.00% idle=99.50% nice=0.00% steal=0.00% | CpuUser=0.00;CpuSystem=0.50;CpuIoWait=0.00;CpuIdle=99.50;CpuNice=0.00;CpuSteal=0.00;30;100

Have defined it in nrpe.cfg:
command[check_cpu_stats]=/usr/local/nagios/libexec/check_cpu_stats $ARG1$

Have defined it in common.cfg
grep check_cpu_stats common.cfg
command[check_cpu_stats]=/usr/local/nagios/libexec/check_cpu_stats $ARG1$

Recycled xinetd services.

Defined the same in Nagios XI server npre.cfg file:
grep check_cpu_stats nrpe.cfg
command[check_cpu_stats]=/usr/lib/nagios/plugins/check_cpu_stats $ARG1$

Have defined the same in Nagios XI commands.cfg
grep check_cpu_stats commands.cfg
command_name check_cpu_stats
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_cpu_stats $ARG1$

And recycled the xinetd service.

When I am executing the below command from the portal or from the server XI I am getting the below error.
COMMAND: /usr/local/nagios/libexec/check_nrpe -H uusrcpmwik00 -t 30 -c check_cpu_stats
OUTPUT: NRPE: Command 'check_cpu_stats' not defined

Attaching the check_npre screenshot, check_cpu_stats, cpu commands screenshot from the portal.
Could you please let me know what am I missing here. Thanks...

This is not necessary on the Nagios XI server.

This needs to be done through CCM, not directly against the flat config files (this is why is it not appearing in CCM)

This should only be defined in one of the two files, not both.

Please execute this command at the command line of your Nagios XI server:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H uusrcpmwik00 -t 30 -c check_cpu_stats

If you get the error OUTPUT: NRPE: Command 'check_cpu_stats' not defined can you please confirm that uusrcpmwik00 is the SAME server as the one that you defined the command in nrpe.cfg/common.cfg.

Try the test again but this time use the IP address of the server:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H the_ip_address_of_uusrcpmwik00 -t 30 -c check_cpu_stats

Recycled xinetd service on both the servers, here is the output.. which is similar to the old

Basically the remote server is saying that it can't find the command defintion.

Can you please upload the following files from the remote server uusrcpmwik00 here:
/usr/local/nagios/etc/nrpe/nrpe.cfg
/usr/local/nagios/etc/nrpe/common.cfg
/etc/xinetd.d/nrpe
