eG Monitoring
 

Measures reported by MuleJmxMemTest

This test continuously monitors the JVM heap usage of each Mule application/domain and reports the percentage of memory utilized and amount of the available free memory. This way, the test forewarns administrators on possible memory contentions before it causes Out of Memory errors which in turn can increase the CPU usage due to full garbage collection events, and turn the application unresponsive.

Outputs of the test : One set of results for each application/domain on the target Mule ESB being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
TotMem Indicates the total amount of memory allocated for the JVM of this application/domain. MB Ideally, the value of this measure should be high.
FreeMem Indicates the amount of memory available for the JVM of this application/domain. MB Ideally, the value of this measure should be high.
UsedMem Indicates the percentage of memory utilized by the JVM of this application/domain. Percent Ideally, the value of this measure should be low.

A value close to 85% is a cause for concern, and it indicates as high memory used.
