Mutiple Instances in Z/Os shows CPU metrics as numbers and not as percentage

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

When utilizing Z/os and splinting more than one JVM in this machine, Introscope do not show the CPU usage for each instance in percentage, imagine that you have 20 Weblogic applications running in a Z/Os with 10 Cores, for each instance Introscope shows the CPU usage only as number, not as percentage, as below:

Process SRB CPU Time Cumulative (usecs)
Process SRB CPU Time Interval Delta (usecs)
Process TCB CPU Time Cumulative (usecs)
Process TCB CPU Time Interval Delta (usecs)
Process Total CPU Time Cumulative (usecs)
Process Total CPU Time Interval Delta (usecs)

Environment

Any Introscope Agent release.

Resolution

This is hard coded and for now it is not possible to get metric values in percentages.
An Idea was raised to be implemented in future releases:
