PidHealthStats
class PidHealthStats
Keys for HealthStats returned from HealthStats.getStats(int) with the UidHealthStats.STATS_PIDS key.
The values coming from PidHealthStats are a little bit different from the other HealthStats values. These values are not aggregate or historical values, but instead live values from when the snapshot is taken. These tend to be more useful in debugging rogue processes than in gathering aggregate metrics across the fleet of devices.
Summary
