Powershell-ITEM via Zabbix-Agent

[piti87]

Hello,

I try to create a Item on den Zabbix-Server for the agent.
I want to get the last update date (windows Updates).

My Key is:
system.run[PowerShell.exe -nologo -command "(Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date)"]

Now I got the error:
In Zeile:1 Zeichen:45
+ (Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select- ...
+ ~
Schlie?ende ")" fehlt in einem Ausdruck.
In Zeile:1 Zeichen:115
+ ... Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date)
+ ~
Unerwartetes Token ")" in Ausdruck oder Anweisung.
+ CategoryInfo : ParserError: ( [], ParentContainsErrorRecordEx
ception
+ FullyQualifiedErrorId : MissingEndParenthesisInExpression

Executed in a powershell-shell as
"Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date"
it works.

Any ideas?

Thanks a lot!

Perhaps it needs the escape symbol to be passed further then, try with triple backslashes:

system.run[PowerShell.exe -nologo -command \\\"(Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date)\\\"]

No, the same result.
Do you know any other method to get the last windows-update-date?
Thank you!

Try escaping the double-quotes ("):

system.run[PowerShell.exe -nologo -command \"(Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date)\"]

Thank you!
I try this. It will work without any errors now, but the result is not the date:

Result:
(Install-Module -Name PSWindowsUpdate -Force; Get-WUHistory | Select-Object -first 1 | Select -ExpandProperty Date)

Okay it works, tanks. There was a refresh-error. Big thanks!
