Error message using NRPE

[DOkuwa]

Merry Xmas and Happy New year
I am monitoring a red hat server using NRPE on Nagios XI
I do get a an error in the GUI such as " (Return code of 255 is out of bounds)"
I am also attaching the message with the GUI
Please help

Please attach your nrpe.cfg from the remote host. I suspect you don't have your commands set up. If you are referencing any configs in your nrpe.cfg, please send those as well (common.cfg would be the most...common).

If you need help finding any of the mentioned files you can use find / -name NameOfFileYouWantToFind

How did you install NRPE? It looks like you used the linux-agent, which means you're using xinetd. Please also attach your /etc/xinetd.d/nrpe

While these articles have different return code #s, they are worth looking at for troubleshooting:

Thanks


I installed nrpe agents on the redhat linux server
I attaching the both files

Do you have some files in /usr/local/nagios/etc/nrpe? You don't have any commands in your nrpe.cfg. In your nrpe.cfg, change debug=0 to debug=1.

Also, what's the output of ll /usr/local/nagios/libexec and grep nrpe /var/log/messages. Please put the output in code blocks or attach a file.

Lastly, can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the ***Download Profile*** button towards the top. If for whatever reason you *cannot* download the profile, please put the output of View System Info (5.3.4+, Show Profile if older) in the thread (that will at least get us some info). This will give us access to many of the logs we would otherwise ask for individually. If security is a concern, you can unzip the profile take out what you like, and then zip it up again. We may end up needing something you remove, but we can ask for that specifically.

You can also generate a profile manually using the script at /usr/local/nagiosxi/html/includes/components/profile/getprofile.sh

That should generate a profile in /usr/local/nagiosxi/var/components/ which you can get off the server with an application such as FileZilla.

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

If you get an error that PROFILE BUILD FAILED, please see https://support.nagios.com/kb/article.p ... ategory=44

What do i need to get in this directory /usr/local/nagios/etc/nrpe and what command - you don't have any commands in your nrpe.cfg. In your nrpe.cfg,
output of ls -al usr/local/nagios/libexec is in attachment and there was no thing from grep nrpe /var/log/messages

[dwhitfield]

What's the output of ll /usr/local/nagios/etc/nrpe? If there isn't a common.cfg, then you need to add commands to your nrpe.cfg. You may need to add them anyway. If you have the common.cfg, can you send it?

All of your plugins are owned by root, so that could potentially be a problem. Please see if the following command resolves the issue for you: chown -r nagios.nagios /usr/local/nagios/libexec

What's the output of ps -aef | grep nrpe?

I would also suggest taking a look at https://support.nagios.com/kb/article/n ... d-612.html

@DOkuwa, Are those plugins from your previous post installed on the Nagios server or on the remote server?
Also, I would like to see the NRPE commands definitions on the remote server. Please upload the contents of this folder: /usr/local/nagios/etc/nrpe in a zip file.
