前面两篇文章已经介绍如何搭建Prometheus和Grafana，本文介绍如何快速监控Spring Boot进程
Prometheus监控系列
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
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
