Subject [jira] [Commented] (HBASE-14743) Add metrics around HeapMemoryManager
Date Fri, 17 Jun 2016 06:08:05 GMT

stack commented on HBASE-14743:
-------------------------------

Thanks for changing name to Memory. I tried the latest patch. I loaded data but all metrics
are zero in jvisualvm looking at the memory bean. Is your experience different? I just build
w/ the patch then launch local instance of hbase with ./bin/hbase start and then I launch
jvisualvm and look at the bean while I put some data in and flush. Thanks.

> it would be good to know how many invocations there have been.
> How many decided to expand memstore.
> How many decided to expand block cache.
> How many decided to do nothing.

> When that's done use those metrics to clean up the tests.
