Exception Events per Second

Microsoft.JEE.APM.PerformanceHealth.ExceptionEventsSec (UnitMonitor)

A performance monitor for the number of exception events that are generated per second for the specific application.

Knowledge Base article:

Summary

The exception events per second monitor tracks the number of events generated by the monitoring agent on the Java Virtual Machine.

Causes

An unhealthy state indicates that the number of exception events generated per second has exceeded the monitored threshold configured for the agent.

Resolutions

Use the events to determine and fix the root cause of the problem.
Modify the performance thresholds used by the agent to be more tolerant.
Add a load balancing solution to the architecture.
