Region server heap used memory usage
Dear all:
Is there any ways to monitor or profiling the memory usage of region server
heap?
For example, how many are assigned to memstore, blockcache, storefileindex
or else.
Thanks.

1.0 hasn't been released yet.
You can get source code from branch-1 of git repo.
Cheers

Thanks zhihong.
Once the region server starts, can the memory size of these buffer (e.g.,
memstore, block cache) be adjusted/resizable dynamically?

Re: Region server heap used memory usage

If you go to region server Web UI, rs-status#memoryStats, you would see
Memstore Size under Server Metrics.
The Stats tab under Block Cache would show statistics of block cache.
The Storefile Metrics tab under Regions would show Index Size.
The above is from 0.98.5 release.
