NCP Checks failing after NCP Agent upgraded to 2.1.8

[Sampath.Basireddy]

After the NCP Agent is upgraded to 2.1.8 on few of our servers, NCP Checks are failing with error "UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details."

Can you show us the actual command, run from the command line along with the output of it for one of the failing checks?

Here it is:

Code: Select all

[root@gmp1 libexec]# /usr/local/nagios/libexec/check_ncpa.py -H server1.ux.corp.local -t ################ -P 5693 -M 'disk/logical/|var/' -u M -w 90 -c 95
UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details.

Code: Select all

[root@gmp1 libexec]# curl -k -XGET "https://localhost:5693/api/system/agent_version?token=################"
{
    "agent_version": "2.1.8"
}[root@gmp1 libexec]#

[lmiltchev]

Can you try removing the "/" after "var" to see if this is going to fix your issue?

Example:

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H server1.ux.corp.local -t ################ -P 5693 -M 'disk/logical/|var' -u M -w 90 -c 95

If this doesn't work, run the check with the "-v" flag for increased verbosity and show the output. Thanks!

Thank You @lmiltchev, that took care of the issue.

Is this some new limitation?

[lmiltchev]

I am not sure if it is a "limitation". When logging to the API (in the GUI), and checking the correct syntax, this is what you see - 'disk/logical/|var'. There is no "/" after "var".

What is the NCPA version that you upgraded from? It's possible that the syntax was changed, but I do not remember if the "/" was present in the older versions. If I knew the version number you upgraded from, I could test it in-house, and check with our developers on that.

NCP Agent was upgraded from 2.1.6 to 2.1.8.

[lmiltchev]

I can verify that in NCPA ver. 2.1.6, the commands worked with or without the "/" at the end, which was a bug that was fixed in the newest versions of the agent. You should not have the trailing slash present at the end.

I will be closing this topic now. If you have any further, unrelated questions please start a new thread. Thank you!
