Question:

 What is “Utilization % (process)”? Why do I see value 0 on some of the servers?

Environment:
All APM Releases.
Answer:

  Utilization % (process) - for the Java Agent process, this is the percentage of total capacity of all processors this process is using. Regardless of how many processors are used, this metric generates only one number. 

  This means the metric is for the percentage of total system CPU being used by the process across all CPUs. Since Introscope doesn't store decimal values, it's likely that 2% of one CPU will be less than 1% of all CPUs (if the server has many processors), and therefore displays as 0%.
