Great thanks!
We tried gc log, and got a piece of below output.
However, it is hard to read.
Is it possible to get some common metrics, e.g. timestamp of GC occourred,
gc paused time, gc count?
We found there is a tool gcanalyze.py might help. But the tool depends on
rpython module.
How to run the tool?
starting gc state: SCANNING
stopping, now in gc state: MARKING
[1cca56e7e5d61f] gc-collect-step}
[1cca56e7e63793] {gc-collect-step
starting gc state: MARKING
number of objects to mark 158 plus 59
stopping, now in gc state: SWEEPING
[1cca56e820f113] gc-collect-step}
[1cca56e8218863] {gc-collect-step
starting gc state: SWEEPING
