Joe,
We have the following bean name and type registered for consumers. There is
also a CheckOffsetLag tool.
kafka:type=kafka.ConsumerStats
/**
* JMX interface for monitoring consumer
*/
trait ZookeeperConsumerConnectorMBean {
def getPartOwnerStats: String
def getConsumerGroup: String
def getOffsetLag(topic: String, brokerId: Int, partitionId: Int): Long
def getConsumedOffset(topic: String, brokerId: Int, partitionId: Int):
Long
def getLatestOffset(topic: String, brokerId: Int, partitionId: Int): Long
}
Thanks,
Jun
