Unclean leader elections occur when there is no qualified partition leader among Kafka brokers. If Kafka is configured to allow an unclean leader election, a leader is chosen from the out-of-sync replicas, and any messages that were not synced prior to the loss of the former leader are lost forever. Essentially, unclean leader elections sacrifice consistency for availability.

The offline log directory count metric indicate the number of log directories which are offline (due to a hardware failure for example) so that the broker cannot store incoming messages anymore.

Any partition without an active leader will be completely inaccessible, and both consumers and producers of that partition will be blocked until a leader becomes available.

The Under min ISR partitions metric displays the number of partitions, where the number of In-Sync Replicas (ISR) is less than the minimum number of in-sync replicas specified. The two most common causes of under-min ISR partitions are that one or more brokers is unresponsive, or the cluster is experiencing performance issues and one or more brokers are falling behind.

The Under replicated partitions metric displays the number of partitions that do not have enough replicas to meet the desired replication factor. A partition will also be considered under-replicated if the correct number of replicas exist, but one or more of the replicas have fallen significantly behind the partition leader. The two most common causes of under-replicated partitions are that one or more brokers is unresponsive, or the cluster is experiencing performance issues and one or more brokers have fallen behind.

Unclean leader elections occur when there is no qualified partition leader among Kafka brokers. If Kafka is configured to allow an unclean leader election, a leader is chosen from the out-of-sync replicas, and any messages that were not synced prior to the loss of the former leader are lost forever. Essentially, unclean leader elections sacrifice consistency for availability.

The offline log directory count metric indicate the number of log directories which are offline (due to a hardware failure for example) so that the broker cannot store incoming messages anymore.

Any partition without an active leader will be completely inaccessible, and both consumers and producers of that partition will be blocked until a leader becomes available.

The request handler idle ratio metric indicates the percentage of time the request handlers are not in use. The lower this number, the more loaded the broker is.

The network processor idle ratio metric indicates the percentage of time the network processor are not in use. The lower this number, the more loaded the broker is.

The Under min ISR partitions metric displays the number of partitions, where the number of In-Sync Replicas (ISR) is less than the minimum number of in-sync replicas specified. The two most common causes of under-min ISR partitions are that one or more brokers is unresponsive, or the cluster is experiencing performance issues and one or more brokers are falling behind.

The Under replicated partitions metric displays the number of partitions that do not have enough replicas to meet the desired replication factor. A partition will also be considered under-replicated if the correct number of replicas exist, but one or more of the replicas have fallen significantly behind the partition leader. The two most common causes of under-replicated partitions are that one or more brokers is unresponsive, or the cluster is experiencing performance issues and one or more brokers have fallen behind.
