1.SpringBoot配置

在pom檔案中加入。

        <dependency>

            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

            </plugin>
        </plugins>
    </build>
 
</project>      

application.yml加入以下配置

management:
  endpoints:
    web:
      exposure:
        include: '*'
  metrics:
    tags:
      application: ${spring.application.name}
  health:
    redis:
      enabled: false      

設定application

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

SpringBoot項目到這裡就配置完成了，啟動項目，通路

http://ip:8080/actuator/prometheus

即可看到傳回值，這些值就是spring boot傳回在前台頁面的資訊。

2.Prometheus配置

在prometheus配置監控我們的SpringBoot應用，完整配置如下所示。

# 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'
    static_configs:
    - targets: ['localhost:9090']
  - job_name: 'springboot_system' #監控任務名稱
    scrape_interval: 5s
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['localhost:8088']    #springboot端口号
         

啟動Prometheus 通路 ip:9090 然後按照下圖操作 即可看到已經注冊到Prometheus 的監控任務

3.Grafana配置

輸入ip:3000 可以進入grafana的可視化界面

配置prometheus資料源  （ip:9090）

這裡填寫你prometheus位址 點選save後 如果失敗會有提示 

然後導入上文下載下傳好的可視化界面模闆

prometheus選項就是上文配置的資料源

出現以上畫面 配置完成！
