Kafka（8）

Kafka可以配置使用JMX进行运行状态的监控，既可以通过JDK自带Jconsole来观察结果，也可以通过Java API的方式来.
关于监控指标的描述，可以参考：http://kafka.apache.org/documentation.html#monitoring
修改bin/kafka-server-start.sh，添加JMX_PORT参数，添加后样子如下
- if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
- export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
- export JMX_PORT="9999"
- fi
通过以下方法获取目标值
- public class KafkaDataProvider{
- protected final Logger LOGGER = LoggerFactory.getLogger(getClass());
- private static final String MESSAGE_IN_PER_SEC = "kafka.server:type=BrokerTopicMetrics,name=MessagesInPerSec";
- private static final String BYTES_IN_PER_SEC = "kafka.server:type=BrokerTopicMetrics,name=BytesInPerSec";
- private static final String BYTES_OUT_PER_SEC = "kafka.server:type=BrokerTopicMetrics,name=BytesOutPerSec";

- private static final String ACTIVE_CONTROLLER_COUNT = "kafka.controller:type=KafkaController,name=ActiveControllerCount";
- private static final String PART_COUNT = "kafka.server:type=ReplicaManager,name=PartitionCount";
- public String extractMonitorData() {
- //TODO 通过调用API获得IP以及参数
- KafkaRoleInfo monitorDataPoint = new KafkaRoleInfo();
- String jmxURL = "service:jmx:rmi:///jndi/rmi://192.168.40.242:9999/jmxrmi";
