Line 173:
Line 174: try:
Line 175: stats['cpuUser'] = 100 * (eInfo['user_time'] - sInfo['user_time']) / sampleInterval / nanos
Line 176: stats['cpuSys'] = 100 * (eInfo['system_time'] - sInfo['system_time']) / sampleInterval / nanos
Line 177: cpuTime = 100 * (eInfo['cpu_time'] - sInfo['cpu_time']) / sampleInterval / (nanos * ticks)
I think
cpuTime = 100 * (eInfo['cpu_time'] - sInfo['cpu_time']) / sampleInterval / nanos
should be correct.
BTW, why do we not report cpuTime to engine together?
Line 178: except (TypeError, ZeroDivisionError) as e:

Line 180: stats['cpuUser'] = 0.0
Line 181: stats['cpuSys'] = 0.0
