Lync Performance Counters

Author by Nathan Lasnoski

Have you wondered how to get the current active call counts for a Lync server?  What about the quantity of calls going through a mediation server?  Here are a few tips that should help you out. Get-CSWindowsService A colleague of mine recently turned me onto an awesome PowerShell command called "Get-CSWindowsService".  The command grabs the current call and conference counts from the Lync deployment and provides it as output. Here is an example: get-cswindowsservice Status   Name            ActivityLevel ------   ----            ------------- Running  MASTER Running  REPLICA Running  RTCSRV          Incoming Requests per Second=0,Messages In Server=8... Running  RTCCAA          Concurrent Calls=0 Running  RTCCAS          Concurrent Conferences=1 Running  RTCRGS          Current Active Calls=0 Running  RTCCPS          Total Parked Calls=0 Running  RTCATS          Current Active Calls=0 Running  RTCIMMCU        Active Conferences=2,Connected Users=3 Running  RTCDATAMCU      Active Conferences=2 Running  RTCAVMCU        Number of Conferences=2,Number of Users=3 Running  RTCASMCU        Active Conferences=2,Connected Users=0 Running  RTCMEDSRV       Current Outbound Calls=0,Current Inbound Calls=2,Cu... Running  RTCMEETINGMCU   Active Conferences=0 Running  FTA PS C:> ******************************* Pretty neat stuff.  Here is the online reference:  http://technet.microsoft.com/en-us/library/gg398803.aspx How do I get all the performance counters for Lync? Get-Counter -ListSet "LS:*" | Select-Object CounterSetName, Description | Format-List Here is some usage (in this case for Mediation Server Inbound Calls): Get-Counter -Counter "LS:MediationServer - 01 - inbound Calls(_total)- 000 - Current" Want a continuous run? Add the "-Continuous" tag Get-Counter -Counter "LS:MediationServer - 01 - inbound Calls(_total)- 000 - Current" -Continuous Here are some good external references: http://blogs.technet.com/b/csps/archive/2011/06/02/gpsperfcounters.aspx http://blogs.technet.com/b/kamehta/archive/2011/07/07/number-of-active-calls-in-lync-mediation-server.aspx Hopefully this helps you out!
