CCDAK · Question #207
You need to set alerts on key broker metrics to trigger notifications in the event that a cluster is unhealthy. What are three minimum broker metrics to monitor for cluster health? (Choose three.)
The correct answer is B. kafka.controller:type=KafkaController,name=OfflinePartitionsCount,partition={partition} C. kafka.controller:type=KafkaController,name=ActiveControllerCount D. kafka.controller:type=ControllerStats,name=UncleanLeaderElectionsPerSec. Monitoring OfflinePartitionsCount helps detect partition availability issues. ActiveControllerCount should be exactly one in a healthy cluster. UncleanLeaderElectionsPerSec tracks unclean leader elections, which can indicate broker or replica problems.
