> We need the following metrics related to RaftLog and RaftLogWorker:
> |raftLogSyncLatency|Time taken to sync raft log|
> |numRaftLogSyncOps|Number of Raft log sync calls with respect to time(equals
> no of FlushStateMacine Calls)|
> |raftLogSynBatchSize|No of raft log entries synced with each flush call|
> |raftLogReadLatency|Time required to read a raft log entry from actual raft
> log file and create a raft log entry (Raft log read latency)|
> |raftLogAppendLatency|Total time taken to append a raft log entry (this also
> includes writeStateMachineData which will vary depending upon the size of the
> data to be written as well as external factors)|
> |raftLogEnqueuedTime|Time of RaftLogEntry in the Raft Log Worker Queue|
> |raftLogQueueingDelay|Time required to enqueue a raft Log entry in raft log
> worker queue|
> |raftLogSegmentLoadLatency|Time required to load and process raft log
> segments during restart|
> |raftLogWorkerQueueSize|Raft log worker queue size which at any time gives
> the no of pending log entries to be committed to the raft log.|
> |raftLogCacheMissCount|Number of RaftLogCacheMisses |
