Nagios Support Forum

Hi Support,

Both Nagiosxi server and NCPA client host are running CentOS Linux release 7.6.1810 (Core) 64bit and were both manually installed via the Nagios repo.

I have been trying to make use of the check_ncpa.py script to execute check_log3.pl script on a remote machine with the NCPA agent installed but I seem to be hitting a brick wall.

I have placed the check_log3.pl script under /usr/local/ncpa/plugins and I also added another plugin to test but that also returns the same results.

I have replaced the token with XXX in the command I ran below and from the log of the NCPA agent
The debug option returns,

The stack trace:Traceback (most recent call last):
File "./check_ncpa.py", line 281, in main
info_json = get_json(options)

raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 500: INTERNAL SERVER ERROR

Currently the ncpa_listener.log returns the following error,

Is there something that I have overlooked?

Let me know if you require any more information.

Hi Support,

found the issue, we were missing the perl modules for os and Nagios, please close this off.
