Prometheus for Spring Boot

快速接入

• 引入Jar包（pom.xml）

<dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-actuator</artifactId>  </dependency>  <dependency>      <groupId>io.micrometer</groupId>      <artifactId>micrometer-registry-prometheus</artifactId>  </dependency>

• 配置metrics（application.properties）

#Metrics related configurations  management.endpoint.metrics.enabled=true  management.endpoints.web.exposure.include=*  management.endpoint.prometheus.enabled=true  management.metrics.export.prometheus.enabled=true

• 查看指标 http://localhost:8080/actuator/prometheus

prometheus监控指标

• 修改Prometheus配置（prometheus.yml）

#Global configurations  global:    scrape_interval:     5s # Set the scrape interval to every 5 seconds.    evaluation_interval: 5s # Evaluate rules every 5 seconds.  scrape_configs:    - job_name: 'spring-boot'      metrics_path: '/actuator/prometheus'      static_configs:        - targets: ['localhost:8080']

• 重启Prometheus

./perometheus --config.file=prometheus.yml

配置Grafana

• 配置指标jvm_memory_committed_bytes

• 再配置更多指标
  • jvm_threads_states_threads
  • jvm_memory_used_bytes
  • process_cpu_usage
  • rate(http_server_requests_seconds_sum[5m])
  • jvm_gc_pause_seconds_count
