-----------------------------------------
Summary: Create metrics associated with RaftLog for RaftServer
Key: RATIS-647
URL: https://issues.apache.org/jira/browse/RATIS-647
Project: Ratis
Issue Type: Sub-task
Components: server
Affects Versions: 0.4.0
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Fix For: 0.4.0
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|
|raftLogWorkerQueueSize
|Raft log worker queue size which at any time gives the no of pending log
entries to be committed to the raft log.|
|raftLogSegmentLoadLatency|Time required to load and process raft log segments
during restart|
