Nagios Support Forum

Hi,
I am having an issue with one of the check where it throws UNKNOWN error. I tried to google it but couldn't able to find much help. I have attached my hosts/service.cfg file if you would like to see my setup.

Attached hosts/service/hostgroup.cfg

Hello, @shamrozkadiwal. Let's try running these commands from the command line(please show me the output):

su - nagios

/usr/local/nagios/libexec/check_ncpa.py -H 10.180.60.26 -P 1248 -t $USER14$ -M cpu/percent -q aggregate=avg -w 90

/usr/local/nagios/libexec/check_ncpa.py -H 10.180.60.26 -P 1248 -t $USER14$ -M cpu/percent -q aggregate=avg -w 90 -v

@npolovenko, my check_ncpa script is in different location.

What is the output of these commands?
- Make sure to change YOURTOKEN in the command below
Additionally, please attach your ncpa.cfg from 10.180.60.26.

@ssax, I have removed my token.

Please attach a sanitized copy of your ncpa.cfg file from the remote host for review.

Additionally, what version of the agent do you have installed on the remote system?

I have attached ncps.cfg file and also we are using nsclient. Sorry I couldn't able to find out the Nsclient version

@shamrozkadiwal, On the windows server type the following link in the web browser.

https://192.168.3.145:5693/gui/api

*Where 192.168.3.145 is the IP address of the Windows server.

Once you're there click on the API menu, then API Endpoint -> system, agent version. This should give you the agent version of the NCPA agent.
From there please try switching the API endpoint to CPU, Disk and Memory and see if it shows any data.

Also, please upload all ncpa logs from the following directory:

C:\Program Files (x86)\Nagios\NCPA\var\log

I couldn't able to find API menu, then API Endpoint -> system, agent
Also, all the log files are empty. I made sure the NCPA servic is running.
