In the Investigator, you do not see under the CPU node of an agent Host Average CPU(5) and Process Load Proportion (%) metrics.
The cause for this is CPUAverage.js is missing from <EM Home>/scripts folder.
To correct this issue, move CPUAverage.js from the <EM Home>/examples/scripts to the <EM Home>/scripts and then restart the EM so it can begin to produce these metrics.
