本文详细介绍如何使用Prometheus和jvm_exporter监控Zookeeper集群，包括配置jmx_exporter，编写zookeeper.yml规则文件，修改zkServer.sh，以及在Prometheus中添加Zookeeper为监控目标。

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
