Percentage VM Memory Utilized

Microsoft.JEE.PerformanceHealth.MemoryUtilizedMonitor (UnitMonitor)

A performance monitor for the percentage of virtual machine memory used on an application server.

Knowledge Base article:

Summary

The memory utilized performance monitor tracks the memory utilization of the Java Virtual Machine associated with the application server.

Causes

An unhealthy state indicates that the memory utilization has exceeded the monitored threshold configured for the application server.

Resolutions

Start the application server with a larger memory configuration.
Move some deployed applications to another application server.
