IIS App Pool monitoring

[mbellerue]

Ack! I bet with Server 2008 you're still on Powershell 2. Can you upgrade to Powershell 4?

Let me speak with the person responsible for this server and I'll get back to you ASAP.

[ssax]

Sounds good, we'll keep an eye out.

Ok, we got PS 4.0 installed. Now I'm seeing this:

Code: Select all

bash-4.2$ /usr/local/nagios/libexec/check_nrpe -H 10.xxx.xxx.xxx -p 5666 -t 60 -c check_ms_iis_application_pool -a '-A Prepaid'
check_ms_iis_application_pool.ps1 : The term
'check_ms_iis_application_pool.ps1' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or
if a path was included, verify that the path is correct and try again.

    + CategoryInfo          : ObjectNotFound: (check_ms_iis_application_pool.p
   s1:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Do you want me to resend my nsclient.ini and the check_ms_iis_application_pool.ps1 scripts?

[ssax]

Yes, please attach them/

Try changing it to:

Code: Select all

[/settings/external scripts/scripts]
check_ms_iis_application_pool = cmd /c echo If (-Not (Test-Path "scripts\check_ms_iis_application_pool.ps1") ) { Write-Host "UNKNOWN: Script `"check_ms_iis_application_pool.ps1`" not found."; exit(3) }; scripts\check_ms_iis_application_pool.ps1 $ARGS$; exit($lastexitcode) | powershell.exe /noprofile -command -

Then restart the nsclient++ service and try again.

PM sent with files requested.

Not getting this response after making the change you recommended:

Code: Select all

[[email protected] ~]$ /usr/local/nagios/libexec/check_nrpe -H 10.xxx.xxx.xxx -p 5666 -t 60 -c check_ms_iis_application_pool -a '-A Prepaid'
UNKNOWN: Script "check_ms_iis_application_pool.ps1" not found.

[ssax]

Do you have the powershell script in the C:\Program Files\NSClient++\scripts directory on the remote system?

Please replace your nsclient.ini with the one I've PM'ed you, make sure the .ps1 plugin is in the scripts directory, then restart the nsclient++ service in services.msc and test again from the XI server.

[rferebee]

Ok, I made the requested changes, ran the check and received this as the return:

Code: Select all

[[email protected] ~]$ /usr/local/nagios/libexec/check_nrpe -H 10.xxx.xxx.xxx -p 5666 -t 60 -c check_ms_iis_application_pool -a '-A Prepaid'

[mbellerue]

Okay, we need to install the scripting tools.

Code: Select all

install-windowsfeature -name Web-Scripting-Tools

Then try the script again. If it fails with the same invalid namespace, run this command and show us the output.

Code: Select all

get-windowsfeature

[rferebee]

Ok, so we finally got the Web Scripting Tools installed. I apologize, I was told by the system administrator that they had already been installed. Turns out they were not...

We've got the check partially working now:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H 10.xxx.xxx.xxx -p 5666 -t 60 -c check_ms_iis_application_pool -a '-A Prepaid'
OK: Application Pool Started but no process is assigned yet "Prepaid" with 0 Applications. {CPU: 0%}{Memory: 0MB} |'pool_cpu'=0%;;;0;100 'pool_memory'=0MB;;;0 'app_count'=0

Is the reason the check isn't reporting any CPU and Memory is because there are no processes assigned to it and 0 applications?
