本次分享 SpringBoot Admin - 应用程序监控预警（钉钉机器人）

概述

生产环境中微服务利用集群服务数量较大，为更快，更准确的在第一工夫监控到服务衰弱状态。应用SpringBoot Admin提供的监控告警性能实现钉钉机器人预警告诉。在Springboot Admin中内置多种开箱即用的监控告警零碎告诉，例如Mail、Slack、Telegram、Hipchat等多种告诉渠道。思考到它所反对的大多是一些国外的支流工具，而目前理论工作场景中大多应用钉钉办公，故本次分享钉钉机器人预警告诉。

疾速开始

  1. 创立钉钉机器人

    创立自定义机器人

    -

    复制 WebHook - token，实现创立

  2. 编码-自定义音讯告诉

    1. 编码 - 钉钉告诉

      public class DingDingNotifier extends AbstractStatusChangeNotifier {        public DingDingNotifier(InstanceRepository repository) {        super(repository);    }        @Override    protected Mono<Void> doNotify(InstanceEvent event, Instance instance) {        String serviceName = instance.getRegistration().getName();        String serviceUrl = instance.getRegistration().getServiceUrl();        String status = instance.getStatusInfo().getStatus();        Map<String, Object> details = instance.getStatusInfo().getDetails();        StringBuilder str = new StringBuilder();        str.append("监控报警 : 【" + serviceName + "】");        str.append("【服务地址】" + serviceUrl);        str.append("【状态】" + status);        str.append("【详情】" + JSONObject.toJSONString(details));        return Mono.fromRunnable(() -> {            DingDingMessageUtil.sendTextMessage(str.toString());        });    }}

    2. 编码 - 钉钉音讯

      public class DingDingMessageUtil {      public static String access_token = "TOKEN";       public static void sendTextMessage(String msg) {       try {           Message message = new Message();           message.setMsgtype("text");           message.setText(new MessageInfo(msg));           URL url = new URL("https://oapi.dingtalk.com/robot/send?access_token=" + access_token);           // 建设 http 连贯           HttpURLConnection conn = (HttpURLConnection) url.openConnection();           conn.setDoOutput(true);           conn.setDoInput(true);           conn.setUseCaches(false);           conn.setRequestMethod("POST");           conn.setRequestProperty("Charset", "UTF-8");           conn.setRequestProperty("Content-Type", "application/Json; charset=UTF-8");           conn.connect();           OutputStream out = conn.getOutputStream();           String textMessage = JSONObject.toJSONString(message);           byte[] data = textMessage.getBytes();           out.write(data);           out.flush();           out.close();           InputStream in = conn.getInputStream();           byte[] data1 = new byte[in.available()];           in.read(data1);           } catch (Exception e) {                      e.printStackTrace();           }      }  }  class Message {     private String msgtype;     private MessageInfo text;     public String getMsgtype() {            return msgtype;     }     public void setMsgtype(String msgtype) {            this.msgtype = msgtype;     }     public MessageInfo getText() {            return text;     }     public void setText(MessageInfo text) {            this.text = text;     } } class MessageInfo {    private String content;    public MessageInfo(String content) {        this.content = content;    }    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }}

    3. 编码 - Application 初始化钉钉告诉

      @EnableAdminServer@EnableDiscoveryClient@SpringBootApplicationpublic class AdminApplication {    public static void main(String[] args) {        SpringApplication.run(AdminApplication.class, args);    }    @Bean    public DingDingNotifier dingDingNotifier(InstanceRepository repository) {        return new DingDingNotifier(repository);    }}

  3. 成绩验证

    • 启动 SpringBoot Admin Server，启动敞开Client服务

结束语

  • 以上就是 SpringBoot Admin - 钉钉预警的示例，另反对多种监控告警告诉，例如 Mail 形式，可自行实际理解。
