NCPA UNKNOWN:Error occurred while running the plugin

This was working but appears to have stopped or causing errors.
COMMAND: /usr/local/nagios/libexec/check_ncpa.py -H webcms1t -t 'secret' -P 5693 -M cpu/percent -w 50 -c 90
OUTPUT: UNKNOWN: Error occurred while running the plugin.
The NCPA is running on Windows 2012 and is version 1.7.2 and I am using Nagios XI 2014R2.0. I would provide logs but not sure on Windows where these logs would be located.

I've seem this error with an older version of the "check_ncpa.py" plugin, which had a bug.
Make a backup of the "old" plugin.
Code: Select all
cd /usr/local/nagios/libexec
mv check_npca.py check_npca.py.old
Download the latest version of the plugin from here:
https://github.com/NagiosEnterprises/nc ... ck_ncpa.py
Install it on your Nagios XI server:
Admin->Manage Plugins->Browse->check_ncpa.py->Upload Plugin
Note: Try running this command BEFORE and AFTER upgrading the plugin:
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H webcms1t -t 'secret' -P 5693 -M cpu/percent -w 50 -c 90
See if it is going to make a difference.
P.S. If you need to see the NCPA logs, they are located on the Windows client, usually in "Program FIles (x86)\Nagios\NCPA\var\" folder.

I updated the plugin and tried running the command but got the same message. I took a closer look on the server and the log files were dated 11/16 and the services are stuck on Starting... I was unable get them to restart or stop so thought maybe a reboot, since after all this corrects 99% of Windows problems
but the services are still stuck at starting.
I am a Linux guy and not that familiar with Windows. I can point and click my way around but is there a way to force kill or force a restart on these ncpa services? This is my only machine running this client so I plan to install on a couple more to see if this is a bug or just a fluke on this particular Windows 2008r2 server. If anyone else has experienced this issue please let me know. I am in the process of trying to figure out what client to run and am leaning towards the ncpa over the NSCP but may have to rethink that decision.

I think I was finally able to get this working. I am going to install on another machine just to validate but I had to set the services to start with a delay and then the NCPA client reported back data and wasn't stuck on starting. Not sure if there was a conflict or what but after a couple reboots I got the same situation but once I delayed it then it started later on and the services showed started.

This is a known issue and other users have set up "delayed" start of NCPA as a workaround. Our developers are looking into this. Let us know if you have any more issues.
