Look for jmx beans under kafka.server. You will see ???MaxLag and
???MinFetchRate. In the normal case, when a broker fails, the controller
will drop the failed broker out of ISR during leader election. So, the
value of replica.lag.time.max.ms doesn't matter. This value only matters
when the controller's decision is delayed somehow. In this case, having a
large replica.lag.time.max.ms may delay the committing of a message.
