IMPALA-13164: Expose more KRPC metrics
Exposes Kudu RPC metrics that are already collected through the rpcz
JSON page: reactor_active_latency, reactor_load_percent, and
rpcs_timed_out_in_queue.
Reactor activity and load can help identify when reactor threads are a
bottleneck on RPC performance. Timed out RPCs could happen after
IMPALA-13130; a non-zero value would signify lost EndDataStream messages
reflecting significant problems in RPC flow in the environment.
Adds deserialization-queue-size and deserialization-queue-wait-time to
datastream-manager metrics to help identify when RPC deserialization is
slow and could benefit from increasing
datastream_service_num_deserialization_threads or the queue size.
