以下是默认的告警规则配置，位于skywalking安装目录下的config文件夹下 alarm-settings.yml文件 中：
rules:
# Rule unique name, must be ended with `_rule`.
service_resp_time_rule:
metrics-name: service_resp_time
op: ">"
threshold: 1000
period: 10
count: 3
silence-period: 5
message: Response time of service {name} is more than 1000ms in 3 minutes of last 10 minutes.
service_sla_rule:
# Metrics value need to be long, double or int
metrics-name: service_sla
op: "<"
threshold: 8000
# The length of time to evaluate the metrics
period: 10
# How many times after the metrics match the condition, will trigger alarm
count: 2
# How many times of checks, the alarm keeps silence after alarm triggered, default as same as period.
silence-period: 3
message: Successful rate of service {name} is lower than 80% in 2 minutes of last 10 minutes
service_p90_sla_rule:
# Metrics value need to be long, double or int
metrics-name: service_p90
op: ">"
threshold: 1000
period: 10
count: 3
silence-period: 5
message: 90% response time of service {name} is more than 1000ms in 3 minutes of last 10 minutes
service_instance_resp_time_rule:
metrics-name: service_instance_resp_time
op: ">"
threshold: 1000
period: 10
count: 2
silence-period: 5
message: Response time of service instance {name} is more than 1000ms in 2 minutes of last 10 minutes
# Active endpoint related metrics alarm will cost more memory than service and service instance metrics alarm.
# Because the number of endpoint is much more than service and instance.
#
# endpoint_avg_rule:
# metrics-name: endpoint_avg
# op: ">"
# threshold: 1000
# period: 10
# count: 2
# silence-period: 5
# message: Response time of endpoint {name} is more than 1000ms in 2 minutes of last 10 minutes

编写一个自己的程序接收SkyWalking中的告警信息，SkyWalking触发告警后立马会通过web钩子发送到自己的程序中。
第一步：创建SpringBoot工程
此步骤就忽略了，不详细讲解第二步：导入SpringBoot-邮箱的jar包
org.springframework.boot spring-boot-starter-mail
第三步：配置yml（application.yml）
host: 为邮箱的地址，我当前使用的是网易邮箱 ，username是邮箱账号 password是邮箱的授权码，而不是邮箱的登录密码，我当前是网易邮箱，需要用此账号登录网易邮箱进行申请。
第四步：创建接受告警信息的实体类
@Data
public class AlarmMessage {
private int scopeId; //告警标识
private String scope; //类型
private String name; //告警的触发详情
private String id0; //告警服务与告警消息的加密文
private String id1; //请求的告警消息的加密文
private String ruleName;
private String alarmMessage; //告警信息
private long startTime; //告警的生产时间
}
第五步：创建controller控制台接受告警
@RestController
@RequestMapping("/webhook")
@Slf4j
public class WebHooks {
@Autowired
private WebHooksService webHooksService;
@PostMapping("/email")
public void email(@RequestBody List alarmMessageList){
try {
if (SystemUtils.isNotEmpty(alarmMessageList)){
webHooksService.sendEmail(alarmMessageList);
}
}catch (Exception e){
e.printStackTrace();
log.error("邮箱发送失败~~~~");
}
}
}
当Skywalking触发告警，就会将告警往这个(/webhook/email)中的进行发送，采用List集合是因为在同一个时间段内会有多个告警同时到来，告警的消息全部在List中怎么做处理根据你们的需求进行编写，我这边是接收到告警后进行发送邮箱。。。
第六步：配置SkyWalking网络钩子
打开skywalking安装目录下的config文件夹下 alarm-settings.yml文件，找到webhooks这个配置项，进行修改
webhooks: - http://xxx.x.x.x/webhook/email
配置刚刚创建的项目路径以及接收告警的控制层，启动skyWalking，当skyWalking触发告警就会立马接收到。。。。。
