Collect .NET CSM Statistic/Avg execution time performance counter (ms)

Summary

The instance state becomes unhealthy if the average request time for the webpage loading on the browser per defined time period exceeds the monitor threshold.

Causes

Transaction performance alerts are generated when the average duration of client-side performance events exceeds the configured monitor threshold.

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

Long server processing might be caused by 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.
