Nagios Support Forum

Trying to build IIS pool checks via NCPA for a server. I tried https://support.nagios.com/forum/viewtopic.php?t=49956 and https://support.nagios.com/forum/viewtopic.php?t=48302, and I am still not having luck. I get the following message in the API:

CRITICAL: Cannot retrieve the dynamic parameters for the cmdlet. Retrieving the COM class factory for component with CLSID {688EEEE5-6A7E-422F-B2E1-6AF00DC944A6} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I am able to run the Powershell script manually and get information. I tried changing the ncpa.cfg to no avail. Any ideas?

$USER1$/check_ncpa.py -H $HOSTADDRESS$ $ARG1$

$ARG1$ = t '*token*' -P 5693 -M 'plugins/check_ms_iis_application_pool_DefaultAppPool.ps1' -q

Hi wkratky,

The Windows version of NCPA is 32-bit. When you run the script manually on the command line are you using a 32 or 64 bit version of powershell ? You can double check with the following:
It would be interesting to trying running the script in both the 64 and 32 versions of powershell to see if there is any difference.

To start a 32-bit shell: To start a 64-bit shell: Thanks and Best Regards,

Powershell:

PS C:\Program Files (x86)\Nagios\NCPA\plugins> .\check_ms_iis_application_pool_DefaultAppPool.ps1
OK: Application Pool Started but no process is assigned yet "DefaultAppPool" with 0 Applications. {CPU: 0%}{Memory: 0MB} | 'pool_cpu'=0%, 'pool_memory'=0MB, 'app_count'=0

Poweshell x86:

PS C:\Program Files (x86)\Nagios\NCPA\plugins> .\check_ms_iis_application_pool_DefaultAppPool.ps1
CRITICAL: Cannot retrieve the dynamic parameters for the cmdlet. Retrieving the COM class factory for component with CLSID {688EEEE5-6A7E-422F-B2E1-6AF00DC944A6} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Hi wkratky,

Bummer - it appears that the script doesn't agree with the 32-bit shell. Your windows knowledge is probably better than mine but doing a little searching it looks like there might be a work around.

Hope this is useful.
