目录(?)[+]

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

开启JMX端口

修改bin/kafka-server-start.sh，添加JMX_PORT参数，添加后样子如下

[html] view plaincopy print?

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
export JMX_PORT="9999"
fi

通过Jconsole测试时候可以连接

通过JavaAPI来访问

通过以下方法获取目标值

[java] view plaincopy print?

public class KafkaDataProvider{
protected final Logger LOGGER = LoggerFactory.getLogger(getClass());
private static final String MESSAGE_IN_PER_SEC = "kafka.server:type=BrokerTopicMetrics,name=MessagesInPerSec";
