------------------------------------
Fix Version/s: Impala 5.0.0
Resolution: Fixed
> Add more TCMalloc metrics
> -------------------------

> Key: IMPALA-14874
> URL: https://issues.apache.org/jira/browse/IMPALA-14874
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Critical
> Fix For: Impala 5.0.0

> Currently, we just track the following TCMalloc metrics:
> * tcmalloc.bytes-in-use
> * tcmalloc.pageheap-free-bytes
> * tcmalloc.pageheap-unmapped-bytes
> * tcmalloc.physical-bytes-reserved
> * tcmalloc.total-bytes-reserved
> It'd be helpful to show more numeric properties from TCMalloc that should
> have minimal overhead to read. E.g.,
> * tcmalloc.current_total_thread_cache_bytes
> * tcmalloc.central_cache_free_bytes
> * tcmalloc.transfer_cache_free_bytes
> * tcmalloc.thread_cache_free_bytes
