> Modify agent to calculate the process usage as follows:
> At the transition from init->run mode:
> capture totalCpuUsage value and save as totalCpuInitUsage
> capture current timestamp and save as clockAtStartOfRun
> On each agent report for the process (or process group?) while in running state:
> compute lastPercentCPU = 100 * (totalCpuUsage - totalCpuInitUsage) / (currentTimestamp - clockAtStartOfRun)
> send lastPercentCPU
> On each agent report after running state ends:
> send lastPercentCPU (e.g. do not recompute)
