Collect .NET CSM Apps/\% of Performance violations/sec

Microsoft.SystemCenter.Apm.CsmApplicationInstance.PerformanceRateMonitor (UnitMonitor)

Collect .NET CSM Apps/\% Performance violations/sec performance counter

Knowledge Base article:

Summary

The instance state becomes unhealthy if the rate of client performance events per defined time period exceeds the monitor threshold.

Causes

Application client-side performance alerts are generated when the rate of performance events exceeds the configured monitor threshold.

This counter reports the number of times a webpage or AJAX call in the monitored application exceeded the acceptable load time per second.

Excessively long network request times might be caused by an unbalanced Network.

Long server processing might be due to complex or inefficient source code.

Page loading time performance issues might occur because of either large page size or a large number of java scripts.

Long Window.OnLoad performance issues might result from long JavaScript handlers execution.

Resolutions

A typical long page load call can be caused by an unbalanced network, long server processing time, long page loading time, or Window.OnLoad time.
