Good day. We have kafka cluster with three kafka brokers. One brokers was fail (process kafka on server was down with error "Too many open files") => we have only two running brokers. But in GUI cloudera (5.13) summary status is Good health.
(every server has 4 disk, so they are called Kafka Broker 4 disk )
In nagios we monitoring health status every service in hadoop cluster. Kafka reports that it has good health, but we want to know that one broker was failed, so expect status kafka cluster, for example, "Concerning", "Bad" anything else, but only not Good.
Tell me please, is there any settings, which we can adjust? (in first picture all setinngs are ON for health alerts)
