Hello, I have few questions regarding garbage collector’s stats on Taskmanagers and any help or further documentation would be great. I have collected “1 second polling requesting" stats on 7 Taskmanagers, through the relative request (/taskmanagers/<idtaskmanager>/) of the Monitoring REST API while a job, that overall took 38 seconds, was running.
This way got 38 records for each TaskManager and focusing on garbage collector’s stats I can see, for example on 1 of the 38th records: - PS-Scavenge.Time: 2597, PS-MarkSweep.Time: 29016; 1. Is It correct to assume they represent the total elapsed time on different GCs (respectively young and old gen)? So, I basically got a running sum distribution? 2. If yes, values are in mills, so 29 sec? 3. Could they be used to get how much time has been wasted in total because of the “Stop-the-world” GCs policy? Finally, on the same record: - PS-Scavenge.Count: 3, PS-MarkSweep.Time: 5, load: 3.73. 4. Is it the “load” value tightly related? Sorry if it has been quite long and thanks a lot. Guido
