check_npre UNKNOWN: No handler for that command”

[bdm0917]

Good Afternoon,

I am having difficulty with the ./check_nrpe -H <Remote Windows IP address> -t 120 -p 5666 -c check_updates for the plugin - Check Windows Updates Powershell. Powershell execution works great, aw well as, command line from inside the remote windows machine; however, when I login into the Nagios server and switch dir to

cd /usr/local/nagios/libexec

And run the following:

./check_nrpe -H <Remote Windows IP address> -t 120 -p 5666 -c check_updates

I receive the following error:

UNKNOWN: No handler for that command” error

Can someone please let me know what I am doing wrong, I have checked the nsc.ini file and everything seems right.
Thanks in advance.

Can you post your nsc.ini here with any sensitive information edited out?

[bdm0917]

Please see text file attached! Thanks

Do any check_nrpe checks work against this machine? It looks like you have a lot of stuff commented out, including ;check_updates=check_updates.vbs

[bdm0917]

Honestly, I am not too sure. All I know is that the remote windows server is reporting metrics back to Nagios Server XI...see attached!

Also, I thought commented line items might be the issue...

Can you update your nsc.ini and uncomment the line specified above?

Code: Select all

;check_updates=check_updates.vbs

Restart the NSClient++ service, and then run a check manually on Nagios for that service. What did the Status Information change to?

[bdm0917]

So I uncommented the line that you specified and restarted the NSC client from the command line...and I get the same status:

UNKNOWN: No handler for that command

The ./check_nrpe -H <Remote Windows IP address> -t 120 -p 5666 -c check_updates -> is commented out using the ;...does that matter?

[rkennedy]

I noticed another check_updates in your config -

Code: Select all

;check_updates=cmd /c echo scripts\Check-Updates.ps1; exit $LastExitCode | powershell.exe -command -

Which script were you using to check this prior? Do you know if both the .vbs and .ps1 files are working?

[bdm0917]

I have uncommented both lines mentioned in this post and I still receive the same error. I am using this doc...https://assets.nagios.com/downloads/nag ... ios-XI.pdf and I haven't tried the *.vbs script this is the only one that I was aware of.

[rkennedy]

It actually looks the .pdf you posted is for the .ps1 script. Can you comment out the check_updates=check_updates.vbs line and then try again?
