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)
Ok we can agree in removing both the ticks and the 100 * from the front,
otherwise it will be 100 times off. I think it makes sense.
cpuTime is reported to engine as part of the cpuIdle, see line 183
Line 178: except (TypeError, ZeroDivisionError) as e:
Line 179: self._log.debug("CPU stats not available: %s", e)
Line 180: stats['cpuUser'] = 0.0
Line 181: stats['cpuSys'] = 0.0
