Performance Counters

Counter Object: Microsoft Provisioning Client

Counter Instance: Trusted Requests

Average Request Latency	Average time for this client to execute a provisioning request. Each call to IProvEngine::SubmitRequest contributes to the average latency of up to the last 100 requests.
Request Rate	Incoming request rate for this client. Each call to IProvEngine::SubmitRequest contributes to the average request rate of transactions per second.
Requests Executing	Number of concurrently executing requests at this client. This counter identifies the total number of concurrent calls to IProvEngine::SubmitRequest.
Total Requests	Number of requests this client has processed. Each call to IProvEngine::SubmitRequest increments this counter.
Total Requests Failed	Total number of failed requests that this client initiated. Each call to IProvEngine::SubmitRequest that returns a failed HRESULT increments this counter.
