Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. scrape_configs: # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config. - job_name: 'My-Spring-Boot-Application' # Override the global default and scrape targets from this job every 5 seconds. https://tonywu1995.github.io/java/spring-boot-monitor-1/ Wed, 22 Sep 2021 22:47:52 +0800 https://tonywu1995.github.io/java/spring-boot-monitor-1/ 前言 常在河邊走那裡不失鞋，當一個後端工程師，常常會遇到上線Application server突然無法壞掉的問題，因此我們需要一個監控的Server來輔助我們上線的Application，本篇將使用Prometheus監控server當作範例來做為展示 步驟 Spring boot 安裝Prometheus Client 在pom.xml上新增兩個dependency spring-boot-starter-actuator: spring boot內建的監控library micrometer-registry-prometheus: 在spring boot上提供prometheus metrics格式 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>io.micrometer</groupId> <artifactId>micrometer-registry-prometheus</artifactId> </dependency> Spring boot 調整設定檔 在applcation.yml 新增下列設定 management: endpoint: health: show-details: always prometheus: enabled: true endpoints: web: exposure: include: prometheus,health metrics: tags: application: ${spring.application.name} health: diskspace: enabled: true defaults: enabled: false 設定好，啟動spring boot即可在http://:/actuator/prometheus看到metrics 參考連結 Spring boot Spring boot Actuator Micrometer Registry Prometheus
