-----------------------------------------
Summary: Add metrics related to leader and follower commits
Key: RATIS-650
URL: https://issues.apache.org/jira/browse/RATIS-650
Project: Ratis
Issue Type: Sub-task
Components: server
Reporter: Shashikant Banerjee
Assignee: Shashikant Banerjee
Fix For: 0.4.0
Following metrics would be useful for measuring how each server is performing
with respect to the incoming load as well as with respect to its peers in terms
of discrepancies with respect to the commit indices.
|appliedIndexToCommitIndexDiff|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.|
|raftServerCommitIndexDiff|difference between the next commitIndex between a
leader and each of its peer. This will give an idea at what of point of time a
follower lags/catches up with respect to leader|
