MockServer Measurements

1) How do you control/trap measurements/transaction counts for the Mock Server. I need to know how many requests were recieved by the mock server and how many it responded to.

2) When I check the preferences HTTP setting "Enable Mock HTTP Log:", I get "ERROR: An error occured [Writer],see error log for details" message for each message sent to the mock server, however the msgs are not processed by the mock server and cause the error below. If I turn off the Enable Mock HTTP Log, the requests are processed successfully.
