prometheus监控jvm

一、GitHub主页：

https://github.com/prometheus/jmx_exporter

https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.14.0/jmx_prometheus_javaagent-0.14.0.jar

下载jmx_prometheus_javaagent-0.14.0.jar

二、新增jmx_exporter配置文件：

vim jmx_exporter_config.yaml

# 新增jmx_exporter配置文件

---   
lowercaseOutputLabelNames: true
lowercaseOutputName: true
whitelistObjectNames: ["java.lang:type=OperatingSystem"]
blacklistObjectNames: []
rules:
  - pattern: 'java.lang<type=OperatingSystem><>(committed_virtual_memory|free_physical_memory|free_swap_space|total_physical_memory|total_swap_space)_size:'
    name: os_$1_bytes
    type: GAUGE
    attrNameSnakeCase: true
  - pattern: 'java.lang<type=OperatingSystem><>((?!process_cpu_time)\w+):'
    name: os_$1
    type: GAUGE
    attrNameSnakeCase: true

三、编辑prometheus配置文件：

vim prometheus/prometheus.yml

# 编辑prometheus配置文件

新增job

- job_name: 'jmx_exporter'
    static_configs:
    - targets: ['192.168.1.113:8585']
      labels:
        instance: jmx_exporter

 

docker restart prometheus2020

重启容器

 

firewall-cmd --zone=public --add-port=8585/tcp --permanent

firewall-cmd --reload

# 开放防火墙8585端口

四、启动jmx_exporter

java -javaagent:./jmx_prometheus_javaagent-0.14.0.jar=8585:jmx_exporter_config.yaml -jar demo-0.0.1-SNAPSHOT.jar

# jmx_exporter并暴露8585端口并加载配置文件
