这个是容器启动的时候去取的默认配置，这里我是直接覆盖掉了它。prom/prometheus这是镜像，如果本地没有，就回去你设置好的镜像仓库去取。文章源自JAVA秀-https://www.javaxiu.com/26225.html

1、Spring Boot 应用暴露监控指标【版本 1.5.7.RELEASE】文章源自JAVA秀-https://www.javaxiu.com/26225.html

首先，添加依赖如下依赖：文章源自JAVA秀-https://www.javaxiu.com/26225.html

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>

采集应用的指标信息，我们使用的是prometheus,相应的我们引入包：文章源自JAVA秀-https://www.javaxiu.com/26225.html

<dependency><groupId>io.prometheus</groupId><artifactId>simpleclient_spring_boot</artifactId><version>0.0.26</version></dependency>

然后，在启动类 Application.java 添加如下注解：文章源自JAVA秀-https://www.javaxiu.com/26225.html

@SpringBootApplication@EnablePrometheusEndpoint@EnableSpringBootMetricsCollectorpublicclassApplication{ publicstaticvoidmain(String[] args){ SpringApplication.run(Application.class, args);  }}

最后，配置默认的登录账号和密码，在 application.yml 中：文章源自JAVA秀-https://www.javaxiu.com/26225.html

security:user:name:userpassword: pwd

启动应用程序后，会看到如下一系列的 Mappings文章源自JAVA秀-https://www.javaxiu.com/26225.html

利用账号密码访问 http://localhost:8080/application/prometheus ，可以看到 Prometheus 格式的指标数据 文章源自JAVA秀-https://www.javaxiu.com/26225.html

2、Prometheus 采集 Spring Boot 指标数据

首先，获取 Prometheus 的 Docker 镜像：文章源自JAVA秀-https://www.javaxiu.com/26225.html

$ docker pull prom/prometheus

然后，编写配置文件 prometheus.yml ：文章源自JAVA秀-https://www.javaxiu.com/26225.html

global:scrape_interval: 10sscrape_timeout: 10sevaluation_interval: 10mscrape_configs:-job_name: spring-bootscrape_interval: 5sscrape_timeout: 5smetrics_path: /application/prometheusscheme: httpbasic_auth:username: adminpassword: 123456static_configs:-targets:-192.168.11.54:8099 #此处填写 Spring Boot 应用的 IP + 端口号

接着，启动 Prometheus :文章源自JAVA秀-https://www.javaxiu.com/26225.html

docker run -d --name prometheus -p 9090:9090-v D:\test\actuator\prometheus\prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

请注意，D:\test\actuator\prometheus\prometheus.yml ，是我的配置文件存放地址，我们需要将它放到容器里面去，所以用了-v来做文件映射。/etc/prometheus/prometheus.yml这个是容器启动的时候去取的默认配置，这里我是直接覆盖掉了它。prom/prometheus这是镜像，如果本地没有，就回去你设置好的镜像仓库去取。文章源自JAVA秀-https://www.javaxiu.com/26225.html

启动完成后用docker ps看下是否已经启动成功，之后打开浏览器输入：http://localhost:9090/targets,检查 Spring Boot 采集状态是否正常,如果看到下图就是成功了。文章源自JAVA秀-https://www.javaxiu.com/26225.html

3、Grafana 可视化监控数据

首先，获取 Grafana 的 Docker 镜像：文章源自JAVA秀-https://www.javaxiu.com/26225.html

$ docker pull grafana/grafana1

然后，启动 Grafana：文章源自JAVA秀-https://www.javaxiu.com/26225.html

$ docker run --name grafana -d -p 3000:3000 grafana/grafana1

接着，访问 http://localhost:3000/ 配置 Prometheus 数据源：文章源自JAVA秀-https://www.javaxiu.com/26225.html
