Microsoft Key Management Service (KMS) Management Pack supports KMS on Windows Server 2012 and later.
Discovers and Monitors:
Key Monitoring Scenarios:
- KMS Service

The primary method of discovery is to search for a registry value "KeyManagementServiceListeningPort" in the following registry key: "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform".
If your KMS is not getting discovered - you can add that registry value.
The default is REG_SZ with "1688"
