Performance counters allow you to monitor specific aspects of work performed on the site or system by service. Performance counters can help you identify and troubleshoot server performance issues.

The following performance counters are accessible for each host instance under the BizTalk:HTTP Receive Adapter and the BizTalk:HTTP Send Adapter performance object categories:

Category Counter Description
