check_sfb_sync is a Nagios / Icinga plugin for checking Microsoft Skype for Business service replication.

I successfully tested the plugin on Windows Server 2008 / 2012 R2 machines running Microsoft Skype for Business services.

The script checks the replication state of Microsoft Skype for Business services - it needs to be executed on the Windows machine, e.g. using NSClient++.

The following example indicates synchronized Microsoft Skype for Business services:

PS >.\check_sfb_sync.ps1
OK: Skype for Business services are synchronized

A faulty server:

PS >.\check_sfb_sync.ps1
CRITICAL: Skype for Business services are NOT synchronized

To install the plugin, move the PowerShell script to the plugins directory of your agent and alter the configuration, e.g. for NSClient++:

...
#check_sfb_sync
check_sfb_sync=C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe c:\NSCP\plugins\check_sfb_sync.ps1

Restart the service and schedule a service check.
