This tab shows a lot of graphs related to VM memory consumption and rate values. We will describe each briefly:
Promotion Rate- the rate (MB/second) at which objects gets promoted from Young to Tenured space
Allocation Rate- the rate (MB/second) at which new objects are being created
Young Generation Used Before GC- the size of Young generation before garbage collection happens (Eden + Survivor spaces)
Young Generation Used After GC- the size of Young generation after garbage collections. Typically, it's the size of Survivor space.
Young Total Size- total size of Young generation.
Tenured Used- the size of allocated memory in the Tenured space at each point of time.
Tenured Total Size- the total Tenured space size at each point of time. Can differ when Adaptive Policy is enabled.
Heap Used Before GC- total Heap occupation before any minor GC event.
Heap Used After GC- Heap occupation after each minor GC.
Heap Total Size- Total heap size.
If any graphs are missing, it means we don't have enough data from raw logs to render it.
