SpringBoot监控

actuator基本使用：

①导入依赖坐标

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

②访问http://127.0.0.1:8080/actuator

{
    "_links":{
        "self":{
            "href":"http://localhost:8080/actuator",
            "templated":false
        },
        "health":{
            "href":"http://localhost:8080/actuator/health",
            "templated":false
        },
        "health-component-instance":{
            "href":"http://localhost:8080/actuator/health/{component}/{instance}",
            "templated":true
        },
        "health-component":{
            "href":"http://localhost:8080/actuator/health/{component}",
            "templated":true
        },
        "info":{
            "href":"http://localhost:8080/actuator/info",
            "templated":false
        }
    }
}

info相关：

http://localhost:8080/actuator/info在application.properties中配置

info.name=lucy
info.age=99

结果：

{"name":"zhangsan","age":"23"}

http://localhost:8080/actuator/health

开启健康检查详细信息:

# 开启健康检查的完整信息
management.endpoint.health.show-details=always

 结果：

{"status":"UP","details":{"diskSpace":{"status":"UP","details":{"total":128726331392,"free":41764163584,"threshold":10485760}},"redis":{"status":"UP","details":{"version":"3.2.100"}}}}

actuator开启所有endpoint(埋点)：

开启所有endpoint，在application.properties中配置：

# 将所有的监控endpoint暴露出来
management.endpoints.web.exposure.include=*

开启所有endpoint的返回结果：

    "_links":{
        "self":{
            "href":"http://localhost:8080/actuator",
            "templated":false

springboot admin图形化界面使用：

SpringBoot Admin 有两个角色，客户端(Client)和服务端(Server)。

以下为创建服务端和客户端工程步骤：

admin-server：

①创建 admin-server 模块

②导入依赖坐标 admin-starter-server

      <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-server</artifactId>
        </dependency>

③在引导类上启用监控功能@EnableAdminServer

@EnableAdminServer
@SpringBootApplication
public class SpringbootAdminServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootAdminServerApplication.class, args);
    }
}

admin-client：

①创建 admin-client 模块

②导入依赖坐标 admin-starter-client

          <dependency>
            <groupId>de.codecentric</groupId>
            <artifactId>spring-boot-admin-starter-client</artifactId>
        </dependency>

③配置相关信息：server地址等

# 执行admin.server地址
spring.boot.admin.client.url=http://localhost:9000
management.endpoint.health.show-details=always
management.endpoints.web.exposure.include=*

④启动server和client服务，访问server，有很多监控到的信息。（某个请求访问的次数，所有的beans，JVM相关的，线程执行情况）
