I'm checking with prometheus using prometheus jmx exporter.
When I shutdown one broker I don't have any line with: "Shrinking ISR from
%s to %s" even though that ISR have been shrinked:
Topic:test-topicPartitionCount:4ReplicationFactor:2
Configs:
Topic: test-topic Part
How are you checking these metrics? They are per leader. That is, if broker
A is the leader for topic partition topic-0 and broker B is a follower,
then shutting down broker B should cause the IsrShrinksPerSec for broker A
to be updated. You would also something like the following in the
server.log
Problems are:
* JMX attribute:
`kafka.server`
Is always 0 for `Count` and all other attributes. If I shutdown any
broker I
would expect that this would increase.
* JMX attribute:
`kafka.server`
Have random behavior sometimes on shutting down broker it increases and
on starting it also
incr
