I finally got my nagios core running for the first time thanks to the help of someone here, but I still have a small problem:
I'm monitoring an interface server that copies files to another and the command I'm running is to verify the age of a file.
If the folder is empty it means everything is fine, but the check_file_age returns an error.
I know that there is a way to ignore the "file missing" using -i but I can't seem to make it work.
The module is working but I don't understand where to put the command.
I'm monitoring another folder at the same server and it works fine, even when there are no files there.
here's how it is set up, the last service is the one returning an error:

The check_files module can accept additional options that control and filter the output. It sounds like one server may have had its nsclient.ini file edited to behave better when there are not results to return. I would check out and compare these files. Feel free to post or PM copies as well if needed -- make sure to redact any sensitive info that may be in them.

I didn't change anything at the nsclient.ini
Here's the file:

Can you share the working command and it's output so we can compare it to the non-working? It's not clear why it would behave differently but perhaps there's a character in there that is causing it to escape.

Then run the command that fails again and then post your nsclient.log file errors. I'm wondering if it may be a permissions issue.
Once it's done you can change the log settings to info or remove the sections and restart the NSClient++ service again so it doesn't affect performance.
