Hi.

I got a request to monitor a Exchange 2013 server. Found a powershell script on the Exchange site.
I've tried to implement it, but run into a few things:

What I did:
Uploaded script to host in ~nsclient++\Scripts
Modified nsclient.ini file (section Wrapped Scripts)
Added command on Nagios Xi server
Added service.

When I click Apply configuration I get an error:

Code: Select all

Error: Service check command 'check_exch_2013_SiteMailbox ' specified in service 'check SiteMailbox' for host 'stb-exch-01' not defined anywhere!

Checked out the commands.cfg. It's there!

Code: Select all

define command {
       command_name                  	check_exch_2013_SiteMailbox 
       command_line                  		$USER1$/check_nrpe -H $HOSTADDRESS$ -c exchange_serverhealth $ARG2$
}

I'm missing something. Is there a clear step-by-step instruction as howto implement a powershell script in Nagios?

**Edit: I got it to work, but the powershell scripts fails with this:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H [IPADDRESS] -t 30 -c exchange_serverhealth -a SiteMailbox
Get-ServerHealth : Cannot process command because of one or more missing mandat
ory parameters: Identity.

The snapin is installed on the host (v1.0)
there's a lot of info out there on "missing mandatory parameter: identity"
But my powershell knowledge is barely existent, therefore at a loss...

Could you post a link to the script that you are attempting to use? I have tried out several of them with minimal issues, and could check this one out too if I have not already.

This the script I tried. But I'm open to suggestions...

OK so based on your output there, the script ran, it got the needed arguent SiteMailbox, however my guess is that the $_.HealthSetName was not properly available on your system. So, let's try this by hand and see what we get. Open a powershell terminal with administrative rights, and run the following commands. Please send back full output sort of anything that needs to be sanitized.

Code: Select all

$status = 0
$HeathSet = "SiteMailbox"
add-pssnapin Microsoft.Exchange.Management.PowerShell.SnapIn
$HealthSetResult = get-serverhealth
$HealthSetResult | fl
$HealthSetResult.HealthSetName | fl

On the third command I'm prompted to enter a "Identity"
When I enter the server name i get :

Code: Select all

WARNING: A server-side Active monitoring operation has failed. Active monitoring operation failed with message: Error

command 4 and 5 give:

I suppose I have get the proper permission first.
What strikes me odd is that the information supplied with this script is insufficient.
There's more to it than just embedding it in the client and creating a service.
Do I have to edit the powershell script in order to set the Identity param?
Or use an $ARGn$ in Nagios?

sorry, I replied with another account. My colleague decided it would be nice to have a common account so we can watch each others posts and progress..
It's me!!

Just to make sure, while I test on one of my systems, are you running this on the exchange server, or is this another system that has access to it? It just seems strange that loading the snapin (presuming thats what you meant by my third command) is asking for identity, as you thought, likely meaning the server you wish to connect to.

Yep, the commands are fired from the exchange server.
By the 3rd I mean the "add-pssnapin" command.
I reckon by the awarded stars on the exchange board, that a number of admins are already using the script.

In addition to the actual exchange services and roles, do you have the exchange management tools installed on this machine? Apparently the snapin only comes with that particular install, which is mostly separate from the main exchange install.
