Alertmanager 数据结构
概述
参考：
- 官方文档，告警 - 客户端(接收告警的数据结构)
AlertManager 接收告警的数据结构
这个数据结构，其实就是 Prometheus 推送告警的数据结构.。。。详见 Prometheus Alerting 章节
[
{
"labels": {
"alertname": "<requiredAlertName>",
"<labelname>": "<labelvalue>",
...
},
"annotations": {
"<labelname>": "<labelvalue>",
},
"startsAt": "<rfc3339>",
"endsAt": "<rfc3339>",
"generatorURL": "<generator_url>"
},
...
]
Alertmanager 通过 Webhook 推送告警的数据结构
参考:
- 官方文档，告警 - 配置 - webhook_config(通过 Webhook 推送告警的数据结构)
下面就是 Alertmanager 在 Webhook 配置中，以 POST 请求发送的 JSON 结构的数据格式：
{
"version": "4",
"groupKey": <string>, // key identifying the group of alerts (e.g. to deduplicate)
"truncatedAlerts": <int>, // how many alerts have been truncated due to "max_alerts"
// 当前发送的告警状态，如果是激活的告警则是 firing，如果是已经解决的则是 resolved
"status": "<resolved|firing>",
"receiver": <string>,
// 根据 AlertManager 配置中 group_by 字段获取。
// 也就是说通过某个标签分组，那么这个标签的名和值都会被写到这个字段中
"groupLabels": <object>,
// 这一组告警中，相同的 Labels 和 Annotations
"commonLabels": <object>,
"commonAnnotations": <object>,
// 反向连接到 Alertmanager，
"externalURL": <string>,
"alerts": [
{
"status": "<resolved|firing>",
"labels": {
"alertname": "<RequiredAlertName>",
"<labelname>": "<labelvalue>",
......
},
"annotations": <object>,
// 告警的触发时间
"startsAt": "<rfc3339>",
// 若 status 字段的值为 resolved，则会显示该告警的结束时间
"endsAt": "<rfc3339>",
// 反向链接到 Prometheus
// URL 包括 prometheus 域名和由生成告警的 promQL 语句。通过该连接，可以直接在 prometheus web 中打开使用指定 promql 查询。
"generatorURL": <string>
},
