Can you try configuring the commands without using arguments? That way we can at least tell if that's part of the issue or not.

What happens if you try to submit the command as the nagios user? It is possible that the application does not have enough permissions to that file.

Code: Select all

su nagios
/usr/local/nagios/libexec/check_file_age -w 500 -c 6000 -f /home/pons/file.txt
ls -l /usr/local/nagios/libexec/check_file_age /home/pons/file.txt

What is the result when you try to use the Run Check Command from the Service Management page? Do you get any specific error messages?

It never hurts to send ( PM ) us a profile either! We can find lots of information about your system in there. You can download the profile by navigating to System Profile under System Config on the left pane > and clicking the Download Profile button on that page.

As i said before from the server command line it works ... when i call the same from the GUI it says file does not exist.
I tried also to adjust the script ... but it didnt work by searching google found many links talking about the perl script adjustment, but still not working.

[jbrunkow]

Yes, but when you ran it from the command line you did so as root. The GUI uses the nagios user. Therefore, it would be a more accurate test to run it as nagios instead of root. This could help us determine if you are encountering a permissions issue or not.

I would also like to reiterate that it would help us if you could send us the output from those commands or a profile.

[fsodah]

You are right from nagios is not working

>>>I would also like to reiterate that it would help us if you could send us the output from those commands or a profile.
What else do you want me to send?
