Health check for data sent from Agent to DX APM SaaS enviroment

Products

• CA Application Performance Management SaaS

Issue/Introduction

It was suggested to open a case investigating why it takes nearly 5 minutes for metric data to populate in DX APM SaaS after an agent starts. 

Is there anything that can be updated in the introscope agent profile to fix this?

Are there other areas of interest to check?

 

Environment

Release : APM SAAS

 

Cause

So it took 2 minutes from start of the Agent to connect to a Collector.  Mostly because it attempts to determine the agent name.  

The Agent connects to the Collector.  Once that happens, metrics will start coming in.  First your base metrics will appear, GC Heap, Agent stats, etc...   Other metrics will start to appear once the application is exercised.  Frontends are usually the last to appear generally because that part of the app must be exercised.

Here we see that the agent name is still being determined and finally used.

Resolution

Please reduce the value of this property in the Agent Profile to 10 seconds. This requires a restart to take effect.
