Prometheus客户端tomcat监控jmx_exporter

上一篇文章讲了监控mysql，同样的，我们这次来监控tomcat，注意监控tomcat需要重启tomcat才能实现。

项目地址：[GitHub - prometheus/jmx\_exporter: A process for exposing JMX Beans via HTTP for Prometheus consumption][GitHub - prometheus_jmx_exporter_ A process for exposing JMX Beans via HTTP for Prometheus consumption]

默认端口：无，需配置时指定

Grafana模板id 8563(JVM dashboard)、3457(JMX Overview)

一、下载安装jmx\_exporter及配置文件

监控tomcat是通过agent.jar实现的

下载agent jar和配置文件

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.16.1/jmx_prometheus_javaagent-0.16.1.jar
    wget https://raw.githubusercontent.com/prometheus/jmx_exporter/master/example_configs/tomcat.yml

将上面的jar包和config配置文件移至tomcat的bin目录下

cp jmx_prometheus_javaagent-0.16.1.jar /usr/local/tomcat/bin/
    cp tomcat.yml /usr/local/tomcat/bin/

修改tomcat的catalina.sh配置文件

JAVA_OPTS="-javaagent:/usr/local/tomcat/bin/jmx_prometheus_javaagent-0.16.1.jar=9018:/usr/local/tomcat/bin/tomcat.yml"

然后重启tomacat

./shutdown.sh
    ./startup.sh

添加防火墙端口

firewall-cmd --zone=public  --add-port=9018/tcp  --permanent
    firewall-cmd --reload

metrics访问地址

[http://10.24.11.202:9018/metrics][http_10.24.11.202_9018_metrics]

ip改成自己的ip

2.服务端prometheus.yml添加节点信息

编辑

vi /usr/local/prometheus/prometheus.yml

添加

- job_name: "202tomcat"
        static_configs:
          - targets: ["10.24.11.202:9018"]
            labels:
              service: tomcat

名称自己起，targets需要配置客户端的ip端口号

重启服务端

systemctl restart prometheus

查看target

3.Grafana添加仪表

然后导入仪表盘插件，先从官网找模板

这里推荐复制id 8563(JVM dashboard)

导入中需要在job里填job名称即202tomcat

仪表如图
