 Some of the Top 5 most important new metrics for APM Team Center are: 

 

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:

• Indicates what's the average response time of all REST API resources for APM Team Center User Interface
• It can point that users are affected by a slow backend.
• Values under 1000ms (1s) are fine, for more than 5000ms, investigate REST API:Concurrent Invocations and REST API:Responses Per Interval to determine if the system is overloaded by requests.

 

4. Metric Name: Database:Edge Count

Metric Path: Enterprise Manager|ApplicationTriageMap|Database:Edge Count

Metric Path: Enterprise Manager|ApplicationTriageMap|Ontology engine:Average Process Time (ms)

What Does it Measure: 

• Indicates what's the average time of processing incoming static and dynamic topology changes for ATC.
• It can point to a problem with processing of changes. There can be some peaks, but average values should be much lower.
