Hi, all: I find that periodical collection of resource usage is implemented by reading '/proc/pid/stat' file once per second, instead of running htop command in shell and parsing output of it, and currently it seems that mesos can only monitor usage of per-process, necessary extention must be made to achieve fine-grained monitoring of each task if wanted, however, we can get usage from htop output directly no matter for a process or task.
Could anybody explain why reading '/proc/pid/stat' file scheme is selected, is there some reasons? Thank you and best regards.
