1. Metric Name: Number of Active Workers

 Metric Path: Enterprise Manager|ApplicationTriageMap:Number of Active Workers

 What does it measure: 

  • Indicates how many threads are currently used from common thread pool of APM Team Center.
  • It can point to overloading issues. The maximum value is 8 and it should be below 2 or 3.


2. Metric Name: Database:Average Response Time (ms)

Metric Path: Enterprise Manager|ApplicationTriageMap|Database:Average Response Time (ms)

What does it measure: 

  • Indicates what is the average time of data processing in APM Database for APM Team Center.
  • It can point to a bad APM Database condition.


3. Metric Name: REST API:Average Response Time (ms)

Metric Path: Enterprise Manager|ApplicationTriageMap|REST API:Average Response Time (ms)

What does it measure:
