springboot+prometheus+grafana搭建应用监控

搭建后的应用信息

springboot应用：192.168.97.128:8001 prometheus:192.168.97.128:9090 (默认配置端口的是9090) grafana:192.168.97.128:3000(默认端口3000，用户名密码 admin/admin)

一、springboot配置

引入项目依赖

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

在yml添加actuator配置,开启监控

management: endpoints: enabled: true web: base-path: /actuator # 访问根路径 exposure: include: "*"

访问http://192.168.97.128:8001/actuator/prometheus，可以看到指标信息。

二、安装配置prometheus

下载linux安装包,tar解压缩 https://github.com/prometheus/prometheus/releases 修改prometheus.yml

# my global config global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. # scrape_timeout is set to the global default (10s). # Alertmanager configuration alerting: alertmanagers: - static_configs: - targets: # - alertmanager:9093 # Load rules once and periodically evaluate them according to the global 'evaluation_interval'. rule_files: # - "first_rules.yml" # - "second_rules.yml" # A scrape configuration containing exactly one endpoint to scrape: # Here it's Prometheus itself. scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. - job_name: 'prometheus' # metrics_path defaults to '/metrics' # scheme defaults to 'http'. static_configs: - targets: ['localhost:9090'] - job_name: 'spring-actuator' metrics_path: '/actuator/prometheus' scrape_interval: 5s static_configs: - targets: ['192.168.97.128:8001']

执行./prometheus --config.file=prometheus.yml启动应用后

访问http://192.168.97.128:9090/targets 可以看到监控应用是否正常

三、安装grafana

下载Grafana:https://grafana.com/grafana/download

wget https://dl.grafana.com/oss/release/grafana-7.0.3-1.x86_64.rpm sudo yum install grafana-7.0.3-1.x86_64.rpm

进行安装 启动服务

service grafana-server start

访问http://192.168.97.128:3000/ 配置datasource,也就是之前yml里prometheus的地址 https://grafana.com/dashboards 可以找到别人已经配置好的监控指标，找一个。下载json文件。
