Enable Logging For RPC Client Access Throttling

 

How to log RPC Client Access Throttling in Exchange 2010?

By default, no RPC Client Access throttling is logged. The common way is to use Perfmon counters to see when throttling occurs. But there is an easier way to log the throttling activity within Exchange. This tip was presented by Scott Schnoll in TechEd 2012.

The logging is enabled by modifying the Microsoft.Exchange.RpcClientAccess.Service.Exe.Config file in the Bin directory.

RPC Config file

Open the config file using notepad and add “Throttling” as a value to the last <add key> line.

Edit RPC Config file

The last line should be as shown below, after the change.

RPC Config after change

Once the change has been made, save the file and restart the RPC Client Access Service. If you have more than one CAS server, make the same change on all of them. Job done!

    Just curious, What we do after that? I mean do we have to put a value into the “” if that the case what should be the recommended value to start with?

      Hi Susantha,

      All throttling events are logged in the \Program Files\Microsoft\Exchange Server\V14\Logging\RPC Client Access folder, once enabled. Check the log files and see whether any parameters have exceeded the value set. Look for the word “exceeded” ;)
