Nagios Support Forum

As requested, file uploaded.
Thank you for your help.
Cheers,

The folder watch script is the same as mine so it isn't a version issue.
The only thing I see different between your debug output and mine is how the date is displayed for the ls -l command

The output on my system This is what yours looks like. I think the difference in the date string is causing the problem.

What Operating system is running on the server you are testing and it's version number as well?
Can you run the following command on the remote system and post it here?

csvdb008:/tmp/nagiosxitest # ls -l

csvdb008:/tmp/nagiosxitest #

Lets set the time-style for your ls command and see if that fixes it. Try running this and see if it works for you.

Still not working

Darn, run the following with the date time string set.

Nope

Try this command. The quotes need to be escaped.
