Can you show an example of what you are trying to define, and what it is throwing out? Maybe we can weasel it in.

We're actively developing a process for checking eventlogs with NCPA which should provide a much cleaner and easier to understand method than this one.

I'm not seven sure how to go about defining it to be honest.

Aren't you just trying to figure out what OS version is being run on the remote side? You said you had a VB script that does what you want. You can use NSClient++ to execute it if you want. Info is at http://nsclient.org/nscp/wiki/guides/na ... al_scripts. But I don't see why you can't just update to the latest version and get the check_os_version method?

Yes, that's correct. I will look into the external scripts option.

I'd like to upgrade but currently don't have a mechanism for updating hundreds of clients. Something I negated to consider when starting this (my bad).

Ahhhh. It wasn't clear that you already had NSClient++ in place. I thought you were going to install it, and couldn't figure out why you didn't just install the latest version.

Okay, good luck.

Yep, external scripts is the place to go, that is how you would be remotely executing plugins/scripts via NSClient++, let us know if you have issues!

OK, had a go at configuring this although I think I'm missing something.

VB script sits in teh scripts folder under NSClient.

Add a command to the external scripts section of nscliet.ini
- check_os_version=script.exe //T:30 //NoLogo scripts\OS_Version.vbs

Running the command line:
- ./check_nrpe -H ipaddress -p 5666 -c check_os_version

I get the following:
ExternalCommands: failed to create process (script.exe //T:30 //NoLogo scripts\OS_Version.vbs): 2: The system cannot find the file specified.

Any ideas?

---------------------------------------------
I should also mention that my vb scripts is pretty simple. Here it is...
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" _
& strComputer & "\root\cimv2")
Set colOperatingSystems = objWMIService.ExecQuery _
("Select * from Win32_OperatingSystem")
For Each objOperatingSystem in colOperatingSystems
Wscript.Echo objOperatingSystem.Caption & _
" " & objOperatingSystem.Version
Next

Thanks,

Can you post the "NSC.ini" (or "nsclient.ini") file for a review? I just tried your script, and I got a different output...

Code: Select all

[root@testbox libexec]# ./check_nrpe -H 192.168.x.x -c check_os_version
CRITICAL: Windows 7 (6.1.7601)|'version'=61;50;50

It has to be a problem with the config.

This should be cscript.exe

Code: Select all

check_os_version=cscript.exe //T:30 //NoLogo scripts\OS_Version.vbs

Make the change, restart NSClient and test.

Curse of the typo!!! My bad... this works a treat if you call cscript properly. Thank you very much!
