监控tomcat 的工具

  • jmx_export
  • jmx_exporter tomcat 配置文件
  • 一个jar项目(jersey-jar.war) 或者 tomcat

jmx_export 项目地址： https://github.com/prometheus/jmx_exporter
在项目中提供了配置文件: https://github.com/prometheus/jmx_exporter/tree/master/example_configs

  1. # jmx agent
  2. git clone https://github.com/prometheus/jmx_exporter
  3. cd jmx_exporter
  4. mvn package
  5. ## 或者直接下载 jar包
  6. wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.11.0/jmx_prometheus_javaagent-0.11.0.jar
  9. # 获得jmx_export  tomcat 的配置文件
  10. # https://github.com/prometheus/jmx_exporter/tree/master/example_configs
  11. cat > tomcat.yml <<EOF
