when i read source code，i can't understand why namedprocess_namegroup_read_bytes_total/namedprocess_namegroup_write_bytes_total can use two collect increasement as counter，this metric use trackedProc lastaccum which comment by "lastaccum is the increment to the counters seen in the last update."，why not use the original value as counter instead of using the increasement？ @rajatvig @flixr
