Spring Boot Metrics使用

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=*

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

1. 查看方式：

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：

   • 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

{

  "git": {
    "commit": {
      "time": "2018-03-25",
