The metric Elapsed Time Average metric does not show the correct value of the average from the minimum and maximum as below:
CA Application Performance Management 10.7 agent release.
Elapsed Time Average is not the average of Elapsed Time Maximum and Elapsed Time Minimum.
Below how the Elapsed Time Average is measured:
MBConstants.ELAPSED_TIME_AVERAGE, elapsedTimeTotal / messageflowInvocationTotal
Elapsed Time Average = Elapsed Time Total / (message flow invocation total)
message flow invocation total = commitCount + backoutCount;
So Elapsed Time Average is NOT an average of Max and Min. Also, there is NO metric as Average for Elapsed Time Maximum and Elapsed Time Minimum.
As a workaround, you can create a calculator from Elapsed Time Maximum and Elapsed Time Minimum. Please refer to the below documentation to accomplish it:
