备忘录二：Spring Boot Actuator+Prometheus+Grafana

一：Spring Boot Actuator

1. Spring-boot-actuator 可在将应用程序投入生产时监视和管理应用程序。可以选择使用 HTTP 端点或 JMX 来管理和监控应用程序

2. Spring boot 应用中引入 Spring-boot-actuator

                                        org.springframework.boot                        spring-boot-starter-actuator                

3.application.yml文件配置

# managementmanagement:  endpoints:    web:      exposure:        include: "*"  endpoint:    health:      show-details: ALWAYS

4.Spring Boot Actuator内置Endpoints

二： Prometheus

1. 将Micrometer Prometheus 注册添加到Spring Boot应用。

                                        io.micrometer                        micrometer-registry-prometheus                

2.Docker 拉取 Prometheus镜像

docker pull prom/prometheus

3. Prometheus 配置文件

# my global configglobal:  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).# 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=` to any timeseries scraped from this config.  - job_name: 'prometheus'    # metrics_path defaults to '/metrics'    # scheme defaults to 'http'.    static_configs:    - targets: ['127.0.0.1:9090']  - job_name: 'spring-actuator'    metrics_path: '/mybatis/actuator/prometheus'    scrape_interval: 5s    static_configs:    - targets: ['112.74.105.178:8888']

4.运行 Prometheus容器

docker run -d --name=prometheus -p 9090:9090 -v /mnt/demo/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus --config.file=/etc/prometheus/prometheus.yml

5.查看 Prometheus运行情况

三：Grafana

1. Docker 运行Grafana镜像

docker run -d --name=grafana -p 3000:3000 grafana/grafana

2. Grafana 配置 Prometheus数据源

3.监控dashboard
