This plugin checks count of hosts activated by KMS server.
This plugin checks count of hosts activated by KMS server.

Key Management Service is a service dedicated handling volume licensing created by Microsoft for Windows (since Vista) and Office (since 2010).

Checking count of activated hosts is important because if it's under activation threshold, KMS server would not activate new hosts until threshold is not reached. If threshold is reached, hosts will be activated successfully (if you would not e.g. move KMS server to different hardware and you must activate server).

This plugin checks whether KMS host can activate given software (e.g. Office 2010/2013/2016, Windows 7) and returns in performance data current activated count(*) and count required for activation to work.

* - this count is only true up to 2*required which is maximum value for this counter; I don't know why, but it's a feature of Get-WmiObject and some Windows/KMS host internals and not a bug of this script
