Hystrix服务监控-蒲公英云

Hystrix服务监控

可以利用hystrix来达到实时的服务监控的功能。

我们新建立一个hystrix-dashboard工程。

pom文件中添加：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2.yaml配置文件就比较简单了：

server:
  port: 9001

3.主启动类上添加：

@EnableHystrixDashboard

4.所有的服务提供者都需要监控依赖配置：

<!-- actuator监控信息完善 -->
   <dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-actuator</artifactId>
   </dependency>
