Nagios Support Forum

Hi All
I am quiet a beginner in nagios. I have found a powershell script to check the certificate expiry on windows machine. And it works directly on the machine. I found the script here

http://exchange.nagios.org/directory/Pl ... ck/details
http://networklore.com/windows-certificate-expiration/

The scripts works fine on the powershell window and I have added the following lines to nsc.ini
[/settings/external scripts/scripts]
check_win_cert=cmd /c echo scripts\nm-check-certificate-expiration.ps1; exit $LastExitCode | powershell.exe -command -

as I found in this thread.

I don't know how to get this working from nagios.

I would appreciate detailed steps and if possible a bit of explanation so that I can learn as well.

Thanks in advance

Hello,

You should be able to make it work if you follow this procedure:

1) Download the script. Put the script in the NSCP scripts folder
2) In the nsclient.ini configuration file, define the script like this:
check_win_cert=cmd /c echo scripts\nm-check-certificate-expiration.ps1 $ARG1$; exit LastExitCode | powershell.exe -command –
3) Make a command in Nagios like this:
check_win_cert => $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -t 60 -c check_win_cert -a $ARG1$
4) Configure your service in Nagios, make use of the above created command. Make sure you use at least one parameter in $ARG1$ (like -w 10 or so)

This webpage from NSClient documentation also describes how to use Powershell files: http://nsclient.org/nscp/wiki/guides/na ... al_scripts

Thank you for your early reply. How do I do step 3?

In Core Config Manager, go to Commands (somewhere bottom left), create a new command there or copy a working command and edit the settings.

ichayan, let us know if WillemDH's suggestion helped.

Thank you for the replies, didn't have access to systems over weekend. Tried it this morning but I am getting error when I test the command in the web interface.

COMMAND: /usr/local/nagios/libexec/check_nrpe -H lync.mydomain.com -p 5666 -t 60 -c check_win_cert
OUTPUT: UNKNOWN: No handler for that command



nsc.ini
========
[/settings/external scripts/scripts]
check_win_cert=cmd /c echo scripts\nm-check-certificate-expiration.ps1; exit $LastExitCode | powershell.exe -command -

enabled modules

NSClientListener.dll
