搭建线上jvm监控

Springboot项目配置

maven依赖

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-actuatorartifactId>
dependency>
<dependency>
    <groupId>io.micrometergroupId>
    <artifactId>micrometer-registry-prometheusartifactId>
dependency>

application.properties

spring.application.name=springboot
server.port=8080
management.endpoints.web.exposure.include=*
management.metrics.tags.application=${spring.application.name}  

添加监控JVM的配置类

@Bean
public MeterRegistryCustomizer<MeterRegistry> configurer(@Value("${spring.application.name}") String applicationName) {
    return registry -> registry.config().commonTags("application", applicationName);
}

启动springboot项目

访问 http://localhost:8080/actuator/prometheus 查看指标是否正常

Prometheus配置

  - job_name: "jvm"
    # 多久采集一次数据
    scrape_interval: 5s
    # 采集时的超时时间
    scrape_timeout: 5s
    # 采集的路径
    metrics_path: '/actuator/prometheus'
    # 采集Springboot服务的地址
    static_configs:
      - targets: ['127.0.0.1:8080']

启动prometheus，查看指标情况 prometheus.exe --config.file=file(此启动方式是windows下，安装包解压后，在项目根目录下执行的命令）

http://localhost:9090/metrics
