Gather Log Analytics/MMA agent version

Had some questions come up from the community to check the Log Analytics agent version.

Depending on how you are setup, the SCOM Integration makes this easy with Holman's blog for the agent management pack.

If you have admin right in Operations Manager console then you can check this directly from SCOM server:

If you are an admin in SCOM, you can check from MS

$Server = "DC01.yourlabnamehere.net"
(Get-SCOMAgent -Name $ServerName).Version

Alternatively, from server registry:

(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\setup")

# Just the Agent version variable

(Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\setup").AgentVersion
