Supratim Deka updated RATIS-670:
--------------------------------
Description:
Plotting the Log apply index (log index applied on the StateMachine) against
the RaftLog commit index, is useful in monitoring the performance of the
statemachine.
This jira adds a metric/gauge which tracks the current value of log apply index.
was:
The following metric will track by how many entries the log apply index is
lagging behind the log commit index for the local Ratis log. It should be noted
that log apply will always lag log commit.
|logCommitToLogApplyDiff|The difference between lastApplied Index and log
Commit Index on each of Ratis server. This will give an indication of how the
stateMachine is behaving with respect to the incoming load.|
