Hi Neil, Yes, I think we should probably report the UncleanLeaderElectionsPerSec metric in KRaft. We don't have it currently.
We do have the concept of unclean leader election in KRaft, but it has to be triggered by the leader election tool currently. We've been talking about adding configuration-based unclean leader election as part of the KIP-966 work. best, Colin On Wed, Oct 18, 2023, at 10:27, Neil Buesing wrote: > Development, > > with Raft controllers, is the unclean leader election / sec metric supose > to be available? > > kafka.controller:type=ControllerStats,name=UncleanLeaderElectionsPerSec > > Nothing in documentation indicates that it isn’t as well as in code > navigation nothing indicates to me that it wouldn’t show up, but even added > unclean leader election to true for both brokers and controllers and > nothing. > > (set this for all controllers and brokers) > KAFKA_UNCLEAN_LEADER_ELECTION_ENABLE: true > > Happy to report a Jira, but wanted to figure out if the bug was in the > documentation or the metric not being available? > > Thanks, > > Neil > > P.S.
