Hello All,

Can you please explain me how I can check specific service on host using NCPA.
This is the line in how it executed when I use NCPA client:
[Wed Sep 17 10:11:38] root@sq5vrlngs001:~# /usr/local/nagios/libexec/./check_ncpa.py -H sq5vpmacc001.tor.quest.com -P 5693 -t ccc-M 'service?service=AirWatchCloudConnector&status=running' -v

Code: Select all

Connecting to: https://sq5vpmacc001.xxx.com:5693/api/service?service=AirWatchCloudConnector&status=running/?token=ccc&check=1

An error occurred:No JSON object could be decoded

If I using same line using Firefox I have following output:
https://sq5vpmacc001.xxx.com:5693/api/s ... cc&check=1

Code: Select all

{
  "value": {
    "returncode": 2, 
    "stdout": "CRITICAL: Service AirWatchCloudConnector is running"
  }
}

But if I change place of "check" option it gives me correct output in Firefox:

https://sq5vpmacc001.tor.quest.com:5693 ... 5vplngs001

Code: Select all

{
  "value": {
    "returncode": 0, 
    "stdout": "OK: Service AirWatchCloudConnector is running"
  }
}

But if I execute the same request and I was not logged-in using Login page, the NCPA will forward me to the login page.

Please see attached video (in rar attached file).

Looks like it is bug, but maybe I do something incorrect.

Thanks

Your check for services should look something like:

Code: Select all

Command definition:
$USER1$/check_ncpa.py -H $HOSTADDRESS$ $ARG1$

Service definition:
$ARG1$ = -t 'mytoken' -P 5693 -M 'service/Schedule/running'

In this case, I am looking for the Schedule service and it to be in a running state. Your command might look like:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H sq5vpmacc001.tor.quest.com -P 5693 -t ccc -M 'service/AirWatchCloudConnector/running' -v

I would note, that your first attempt likely had issues due to your token of ccc not having a space between it and the -M flag, just another possibility of what could have been happening. Can I ask why you are not using the wizard? It should make this much easier on you, unless of course you just need a few small additions to an existing host.
