Powershell script execution as a UserParameter - working but not working

[diezc]

Hi,
For the past few days i've been trying to set up a userparameter under windows server 2008 r2 that runs a powershell script.
I have this same userparameters and scripts running under windows server 2012R2 and working fine.

My issue is, that when i execute the script from the cmd, i get the correct execution however whener it is called by the zabbix agent, i believe it is calling a 32bit version of powershell for wich some of my items just dont work. Has anyone had problems like this?

UserParameter=apppool.discovery,powershell -NoProfile -ExecutionPolicy Bypass -File "C:\ZabbixAgent\userparams_scripts\get_apppool.ps1"

Running the script from the cmd works fine:

C:\ZabbixAgent\userparams_scripts>powershell -NoProfile -ExecutionPolicy Bypass
-File get_apppool.ps1
{
 "data":[

{ "{#APPPOOL}" : "borrar" },
{ "{#APPPOOL}" : "clasico2" },
{ "{#APPPOOL}" : "ws_predictor" }

 ]
}

C:\ZabbixAgent\userparams_scripts>

However, when i call it using zabbix_get:

zabbix_get -s 10.XX.XX.34 -p 10050 -k site.discovery
Get-ChildItem : Cannot retrieve the dynamic parameters for the cmdlet. Retrievi
ng the COM class factory for component with CLSID {688EEEE5-6A7E-422F-B2E1-6AF0
0DC944A6} failed due to the following error: 80040154.
At C:\ZabbixAgent\UserParameterScripts\get_sites.ps1:2 char:23
+ $sites = Get-ChildItem <<<< -Path IIS:\Sites -Name

indingException
+ FullyQualifiedErrorId : GetDynamicParametersException,Microsoft.PowerShe
ll.Commands.GetChildItemCommand

{
"data":[

{ "{#SITE}" : "" }

]
}

How exactly does the zabbix agent call for cmd commands?
Anyhelp will be welcome!

Hi diezc,

I'm experiencing exactly this, where did you get with this?

Did you manage to get any progress?

In my case, I'm trying to get a registry key...

 zabbix_get -s city.elements.symplectic.org -k ps[]
Get-ChildItem : Cannot find path 'HKEY_LOCAL_MACHINE\SOFTWARE\somekey'
because it does not exist.
At line:1 char:3
+ $(Get-ChildItem Registry::HKEY_LOCAL_MACHINE\SOFTWARE\somekey)
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (HKEY_LOCAL_MACHINE\SOFTWARE\somekey:String) [Get-ChildItem], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand

The funny thing is that this exact same thing works on some server and don't work on this one. I have check versions of PS, I have checked that the Key is in fact there and permissions all looks good.

Can anyone assist with this?

Kind regards and thanks.

Dear Maco1717,

We ran into the same problem, and i saw your post on reddit.
We solved this by switching to the 64bit agent downloaded from the zabbix website

We are using the 4.0.6 agent MSI installer from https://www.zabbix.com/download_agents#tab:40LTS

4.0.6	Windows (msi)	amd64	OpenSSL	896c104d8ddb23ba69cdd5bc59f3e7f7

Hope that this solves your problem.
Good luck
