Spring Boot 使用Metrics监控

1. 导入pom依赖

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

1. 配置项中启用 metrics

management.endpoints.web.exposure.include=*

1. 需要监控调用次数的Controller配置如下：

    @GetMapping("/dic")
    @Timed(value = "all.people", longTask = true)
    public String list() throws JsonProcessingException {
        return objectMapper.writeValueAsString(dictDao.list());
    }

1. 查看方式：
   http://127.0.0.1:8080/actuator/metrics/all.people

2. Spring Boot官网配置

Spring Boot Metrics中查看版本等信息

1. 配置项中启用：

management.endpoints.web.exposure.include=*

1. 配置项中以info开头的配置，都会在info中显示
2. info中显示git信息
   
   • 在classpath中添加git.properties 配置文件

git.branch=master
git.commit.id=sdxe2jdd
git.commit.time=2018-03-25

1. 查看info信息
   http://127.0.0.1:8080/actuator/info

{
  "version": "1.0.0",
  "git": { "commit": { "time": "2018-03-25", "id": "sdxe2jd" }, "branch": "master" } }
