jmx_prometheus方式监控zk指标

Posted 2022-09-27

一、下载jmx_prometheus_javaagent和zookeeper.yaml

#下载jmx程序包
cd /usr/local/src/
wget https://raw.githubusercontent.com/prometheus/jmx_exporter/master/example_configs/zookeeper.yaml
wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.6/jmx_prometheus_javaagent-0.6.jar

#移动到zookeeper程序目录
mkdir /usr/local/zookeeper/prometheus/
mv zookeeper.yaml /usr/local/zookeeper/prometheus/
mv jmx_prometheus_javaagent-0.6.jar /usr/local/zookeeper/prometheus/

二、配置jmx_prometheus

cat > /usr/local/zookeeper/conf/java.env <<\\EOF
export JMX_DIR="/usr/local/zookeeper/prometheus"
export SERVER_JVMFLAGS="-javaagent:$JMX_DIR/jmx_prometheus_javaagent-0.6.jar=9505:$JMX_DIR/zookeeper.yaml $SERVER_JVMFLAGS"
EOF

三、然后重启zookeeper

#服务停止
/usr/local/zookeeper/bin/zkServer.sh stop

#服务启动
/usr/local/zookeeper/bin/zkServer.sh start /usr/local/zookeeper/conf/zoo.cfg

#查看指标了
curl localhost:9505/metrics

四、修改prometheus配置

cat > /home/prometheus/prometheus.yml <<\\EOF
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
   - job_name: zookeeper
     static_configs:
      - targets: [192.168.56.11:9505]
        labels:
          instance: 192.168.56.11_9505
EOF

#重启prometheus
docker restart prometheus

五、grafna导入视图

#注意使用在使用rate或者irate的时候，范围需要大于注意上报的最小时间间隔
rate(process_cpu_seconds_totaljob="zookeeper"[5m])
