一、GitHub主頁：

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

下載jmx_prometheus_javaagent-0.14.0.jar

二、新增jmx_exporter配置檔案：

vim jmx_exporter_config.yaml

# 新增jmx_exporter配置檔案

---
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、編輯prometheus配置檔案：

vim prometheus/prometheus.yml

# 編輯prometheus配置檔案

新增job

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

docker restart prometheus2020

重啟容器

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

firewall-cmd --reload

# 開放防火牆8585埠

四、啟動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並暴露8585埠並載入配置檔案
