Prometheus jvm_exporter监控zookeeper

Zookeeper

Prometheus 监控zookeeper使用jvm_exporter来采集数据，jvm_exporter是一个可以配置抓取和暴露JMX目标的mBeans的收集器。

下载javaagent

cd /usr/local/zookeeper/prometheus

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.3.1/jmx_prometheus_javaagent-0.3.1.jar

编写zookeeper.yml文件

rules:

  # replicated Zookeeper

  - pattern: "org.apache.ZooKeeperService<name0=ReplicatedServer_id(\\d+)><>(\\w+)"

    name: "zookeeper_$2"

  - pattern: "org.apache.ZooKeeperService<name0=ReplicatedServer_id(\\d+), name1=replica.(\\d+)><>(\\w+)"

    name: "zookeeper_$3"

    labels:

      replicaId: "$2"

  - pattern: "org.apache.ZooKeeperService<name0=ReplicatedServer_id(\\d+), name1=replica.(\\d+), name2=(\\w+)><>(\\w+)"

    name: "zookeeper_$4"

    labels:

      replicaId: "$2"

      memberType: "$3"

  - pattern: "org.apache.ZooKeeperService<name0=ReplicatedServer_id(\\d+), name1=replica.(\\d+), name2=(\\w+), name3=(\\w+)><>(\\w+)"

    name: "zookeeper_$4_$5"

    labels:

      replicaId: "$2"

      memberType: "$3"

  # standalone Zookeeper

  - pattern: "org.apache.ZooKeeperService<name0=StandaloneServer_port(\\d+)><>(\\w+)"

    name: "zookeeper_$2"

  - pattern: "org.apache.ZooKeeperService<name0=StandaloneServer_port(\\d+), name1=InMemoryDataTree><>(\\w+)"

    name: "zookeeper_$2"

修改bin/zkServer.sh文件

if [ "x$SERVER_JVMFLAGS"  != "x" ]

then

    JVMFLAGS="$SERVER_JVMFLAGS $JVMFLAGS"

fi

## 新增javaagent

JMX_DIR="/usr/local/zookeeper/prometheus"

JVMFLAGS="$JVMFLAGS -javaagent:$JMX_DIR/jmx_prometheus_javaagent-0.3.1.jar=9505:$JMX_DIR/zookeeper.yml"

if [ "x$2" != "x" ]

then

    ZOOCFG="$ZOOCFGDIR/$2"

fi

验证

curl localhost:9505/metrics

加入Prometheus

编辑prometheus.yml文件，添加内容

- job_name: 'zookeeper'

    static_configs:

    - targets: ['172.16.10.62:9505']

重启prometheus，然后在Prometheus页面中的Targets中就能看到新加入的zookeeper
