THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

We propose adding the following new metrics.:
Name | Context | Type | Mode | Description |
---|---|---|---|---|
kafka.controller:type=KafkaController,name=TimedOutBrokerHeartbeatCount | Controller | Long | KRaft only | The number of broker heartbeats that timed out on this controller since the process was started. Note that only active controllers handle heartbeats, so only they will see increases in this metric. |
kafka.controller:type=KafkaController,name=EventQueueOperationsStartedCount | Controllers | Long | KRaft only | The total number of controller event queue operations that were started. This includes deferred operations. |
kafka.controller:type=KafkaController,name=EventQueueOperationsTimedOutCount | Controllers | Long | KRaft only | The total number of controller event queue operations that timed out before they could be performed. |
kafka.controller:type=KafkaController,name=NewActiveControllersCount | Controller | Long | KRaft only | Counts the number of times this node has seen a new controller elected. A transition to the "no leader" state is not counted here. If the same controller as before becomes active, that still counts. |
kafka.server:type=MetadataLoader,name=CurrentMetadataVersion | Broker and Controller | Integer | KRaft only | Outputs the feature level of the current effective metadata version. |
kafka.server:type=MetadataLoader,name=HandleLoadSnapshotCount | Broker and Controller | Long | KRaft only | The total number of times we have loaded a KRaft snapshot since the process was started. |
kafka.server:type=SnapshotEmitter,name=LatestSnapshotGeneratedBytes | Broker and Controller | Long | KRaft only | The total size in bytes of the latest snapshot that the node has generated. If none have been generated yet, this is the size of the latest snapshot that was loaded. If no snapshots have been generated or loaded, this is 0. |
kafka.server:type=SnapshotEmitter,name=LatestSnapshotGeneratedAgeMs | Broker and Controller | Long | KRaft only | The interval in miliseconds since the latest snapshot that the node has generated. If none have been generated yet, this is approximately the time delta since the process was started. |
kafka.server:type=ForwardingManager,name=QueueTimeMs | Broker | Histogram | KRaft and ZK | A histogram describing the amount of time in milliseconds each admin request spends in the broker's forwarding manager queue, waiting to be sent to the controller. This does not include the time that the request spends waiting for a response from the controller. |
kafka.server:type=ForwardingManager,name=QueueLength | Broker | Integer | KRaft and ZK | The current number of RPCs that are waiting in the broker's forwarding manager queue, waiting to be sent to the controller. |
kafka.server:type=ForwardingManager,name=RemoteTimeMs | Broker | Histogram | KRaft and ZK | A histogram describing the amount of time in milliseconds each request sent by the ForwardingManager spends waiting for a response. This does not include the time spent in the queue. |
