2.收集tomcat数据
Jar包应用
安装github上的方式启动就好了
java -javaagent:./jmx_prometheus_javaagent-0.3.0.jar=9151:config.yaml -jar yourJar.jar
Tomcat war包应用
进入bin目录$TOMCAT_HOME/bin，将jmx_exporter.jar包文件和config.yaml文件复制到这里。然后修改里面的一个catalina.sh的脚本，找到JAVA_OPTS,加上以下配置(代理)：
如果有多tomcat,建议将jmx_prometheus_javaagent和config.yaml文件放到固定的目录,$TOMCAT_HOME/bin/catalina.sh文件中写绝对路径.
#修改bin/catalina.sh 文件
添加：
JAVA_OPTS="-javaagent:bin/jmx_prometheus_javaagent-0.3.1.jar=39081:bin/config.yaml"
访问服务器上的39081端口,查看是否采集到数据

3.配置Prometheus
添加自动发现文件
[root@localhost prometheus]# vim /opt/prometheus/prometheus.yml
- job_name: 'tomcat'
file_sd_configs:
- files: ['/opt/prometheus/sd_config/tomcat.yml']
refresh_interval: 180s
配置文件
[root@localhost prometheus]# vim /opt/prometheus/sd_config/tomcat.yml
- targets:
- 192.168.1.47:39081
labels:
idc: bj_company
service: tomcat
重载配置文件
kill -hup `ps -ef |grep prometheus|grep -v grep|awk '{print $2}'`
到Prometheus控制台查询

4.配置grafana
导入模板, 需要略作修改就可以使用了
