eG Monitoring
 

Measures reported by SapWasHeapTest

This test continuously monitors the JVM heap usage of the target SAP Web Application server and promptly alerts administrators when memory usage is at the maximum.

Outputs of the test : One set of results for each Process:Type of Garbage Collection triggered on the target SAP Netweaver Application Server being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
usedMem Indicates the amount of memory utilized by this heap area. MB Ideally, the value of this measure should be low. A high value or a consistent increase in the value could indicate gradual erosion of memory resources.

Compare the value of this measure across heap areas to figure out the heap area that is utilizing the maximum amount of memory.
pctUsedMem Indicates the percentage of memory utilized by this heap area. Percent A value close to 100 indicates that the heap area is running out of memory.
maxMem Indicates the maximum amount of memory allocated to this heap area. MB  
availMem Indicates the total amount of memory that is available for use by this heap area. MB The value of this measure is the sum of Standby memory and Free Memory.
freeMem Indicates the amount of memory released by the objects per garbage collection operation of this type. MB Ideally, the value of this measure should be high.
initMem Indicates the rate at which garbage collection operations of this type occurred. MB
