NSClient++ ...can't get it to run external scripts

[lyle]

I"m sorry to ask an NSClient++ question here, but I seem to be locked out of the NSClient++ forum, and resetting my password there isn't working. Maybe someone here has advice until I can post in the proper forum.

I can't get an external script to run from NSClient++. The host is a Windows 2008 box with NSClient++ 0.3.8.76

In the NSC.ini file, I've left it pretty much stock. But in the NRPE section, I've un-commented "check_es_ok=scripts\check_ok.bat" which points to the distributed check_ok.bat

From the Nagios server, calling an internal command:

Code: Select all

check_nrpe -H <our host> -c CheckCPU -a warn=80 crit=90 time=4s

runs fine

But this

Code: Select all

check_nrpe -H <our host> -c check_es_ok

returns "UNKNOWN: No handler for that command"

I turned on debugging in NSC.ini, but the debug log file just shows "Injecting: check_es_ok:" and then "No handler for command: 'check_es_ok'"

I've tried using check_es_ok="c:\Program Files\NSClient++\scripts\check_ok.bat" (the full directory spec) in NSC.ini, but that doesn't work.
I've tried enabling "script_dir=scripts", with and without the full directory spec, then using "-c check_ok" and "-c check_ok.bat" in the check_nrpe call, but none of that works. Of course, I'm restarting the service after every config change.

Any thoughts are appreciated. Thanks....Lyle

This is something we probably need to document on our end, because we've had this question come up before, but I don't know if we've ever actually set it up ourselves. Here's what exists for NSClient's documentation on it.

And here's an example from exchange:

lyle,

You have un-commented "check_es_ok=scripts\check_ok.bat" in the NSC.ini file but did you un-comment the "CheckExternalScripts.dll" line in the [modules] section?
If you forgot to do so, you can try un-commenting it, then restart the nsclient++ service and give your command a try one more time.

Let us know if this helped.

Of course! Un-comment "CheckExternalScripts.dll" What a dummy...

Thanks....Lyle

I'm glad I could help!
