Issue:
The .NET Perfmon Collector agent is showing a gradual increase in the historical metric count which if unchecked will eventually cause the agent to be clamped on the Enterprise Manager
Resolution:
Identified via metric count tab in the investigator using a 30 day view that the growing number of dynamic metrics were being collected under Perfmon|.NET Data Provider for SQL Server.

This was defined in the agent profile query property introscope.agent.perfmon.metric.filterPattern

This was modified and teh following string removed |.NET Data Provider*|*|* from the query

That metric branch stopped reporting after perfmon restart
