Description James Sutherland CLA 2010-08-04 13:25:04 EDT 
We currently provide a PerformanceProfiler which is good for single threaded use cases, but not very useful in a server environment.

We provide a QueryMonitor but it only monitors query usage.

We have existing API hooks for monitoring timers, counters, and info, but do not provide a profiler that makes use of these.

The PerformanceMonitor will keep tracking of timers and counter for all query, cache, transaction, connection operations.  These statistic will be accessible by the user and configurable to print to the log every time period (default is 1 minute).
