prometheus 监控 zookeeper + zookeeper概念和意义

1.zookeeper的规则

[root@do1cloud01 prometheus]# cat zookeeper.yml
rules:

  - 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"

  - 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"

2.修改bin/zkServer.sh文件

 参考：https://www.cnblogs.com/bigberg/p/10118555.html

if [ "x$SERVER_JVMFLAGS" != "x" ]
then
JVMFLAGS="$SERVER_JVMFLAGS $JVMFLAGS"
fi
JMX_DIR="/usr/local/zookeeper/prometheus"
JVMFLAGS="$JVMFLAGS -javaagent:$JMX_DIR/jmx_prometheus_javaagent-0.3.1.jar=9505:$JMX_DIR/zookeeper.yml"
