Install first Grafana：

Docker Deploy visual monitoring tools Grafana

Install again Prometheus And configure to Grafana

download JMX Exporter Of jar Package for monitoring JVM Information

To collect JVM Information , You can start Java Passed at the time of the project JMX Exporter（ Download address ：https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/ ） To collect . With jmx_prometheus_javaagent-0.12.0.jar For example .

1. download ：

wget https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.12.0/jmx_prometheus_javaagent-0.12.0.jar

You can also download it locally and send it to the server .

New configuration file simple-config.yml

touch simple-config.yml

vim simple-config.yml

    attrNameSnakeCase: true

Use JMX Exporter Plugins collect data , start-up jar The package needs to be changed to this ：

java -javaagent:/home/jar/demo/jmx_prometheus_javaagent-0.12.0.jar=8037:/home/jar/demo/simple-config.yml -jar swagger-0.0.1-SNAPSHOT.jar

【 Be careful 】 Record here 8037 The port number and IP Address follow up Prometheus Use in profile
The structure here is like this ：

modify prometheus.yml

lookup scrape_configs node , Increase monitoring Job Child node , Examples are as follows ：

  - job_name: 'java'
    scrape_interval: 30s
    static_configs:
- targets: ['120.48.54.67:8037']

restart Prometheus service
