springboot admin监控告警

# 概述 #

Spring Boot Actuator提供了对单个Spring Boot的监控，信息包含：应用状态、内存、线程、堆栈等等，比较全面的监控了Spring Boot应用的整个生命周期；如果Spring Boot应用集群非常大，每个应用都需要调用不同的接口来查看监控信息，国外一个大神开源了一个平台Spring Boot Admin可以用来监控springboot应用集群；  
如果结合注册中心可自动从注册中心获取springboot应用信息并自动监控，其中一个特性比较有用，就是服务上线下线通知；

### springboot admin消息通知 ###

Spring Boot Admin 本身提供监控告警功能，但是默认只提供了Hipchat、Slack等国外流行的通讯软件的集成；默认也支持邮件通知，本示例主要考虑到国内很多公司使用钉钉进行办公交流，故扩展了钉钉机器人通知；

### 邮件通知 ###

配置如下，可自行修改

spring.mail.host=smtp.163.com
    spring.mail.username=XXXX@163.com
    spring.mail.password=88888898989898
    spring.mail.properties.mail.smtp.auth=true
    spring.mail.properties.mail.smtp.starttls.enable=true
    spring.mail.properties.mail.smtp.starttls.required=true
    # 发送给谁
    spring.boot.admin.notify.mail.to=XXXXX@gmail.com
    # 是谁发送出去的
    spring.boot.admin.notify.mail.from=XXX@163.com
    spring.boot.admin.notify.mail.enabled=false

### 钉钉机器人开通方法 ###

1.  新建一个群聊；
2.  添加钉钉机器人；

1.  将钉钉机器人webhook-token配置到项目中，当有服务上下线的时候即会有消息通知；  
    PS:关于钉钉机器人更详细的文档请参见:  
    [https://open-doc.dingtalk.com/docs/doc.htm?spm=a219a.7629140.0.0.xSiICS&treeId=257&articleId=105735&docType=1\#s0][https_open-doc.dingtalk.com_docs_doc.htm_spm_a219a.7629140.0.0.xSiICS_treeId_257_articleId_105735_docType_1_s0]

注意：admin的客户端需要引入springboot actuator组件来暴露相关统计端点；

### 消息格式的自定义 ###

默认的消息格式：

ADMIN-SERVER (f21947a7) status changed from DOWN to OFFLINE  http://8341a1abad80:8088/health

可自定义，默认的消息对象中包含的信息：

{
      "from": { "status": "UNKNOWN", "timestamp": 1528357849054, "details": {} },
      "to": { "status": "OFFLINE", "timestamp": 1528357867912, "details": { "exception": "org.springframework.web.client.ResourceAccessException", "message": "I/O error on GET request for \"http://10.42.42.210:80/health\": Connect to 10.42.42.210:80 [/10.42.42.210] failed: connect timed out; nested exception is org.apache.http.conn.ConnectTimeoutException: Connect to 10.42.42.210:80 [/10.42.42.210] failed: connect timed out" } },
      "application": { "id": "291f245e", "name": "SPARTA-F:1.0.0", "managementUrl": "http://10.42.42.210:80/", "healthUrl": "http://10.42.42.210:80/health", "serviceUrl": "http://10.42.42.210:80/", "statusInfo": { "status": "OFFLINE", "timestamp": 1528357867912, "details": { "exception": "org.springframework.web.client.ResourceAccessException", "message": "I/O error on GET request for \"http://10.42.42.210:80/health\": Connect to 10.42.42.210:80 [/10.42.42.210] failed: connect timed out; nested exception is org.apache.http.conn.ConnectTimeoutException: Connect to 10.42.42.210:80 [/10.42.42.210] failed: connect timed out" } }, "source": "discovery", "metadata": {}, "info": { "timestamp": 0, "values": {} } },
      "timestamp": 1528357867912,
      "type": "STATUS_CHANGE" }
