在prometheus警报配置中添加端点作为接收器

Question

我正试图用警报激活我的春季启动应用程序端点，因为prometheus的警报规则中定义的所需事件已损坏，所以我想将我的应用程序端点添加为接收器，以接收来自prometheus-alertmanager的警报。有人能建议如何将端点配置为此receiver标签的接收器，而不是任何其他推送通知程序吗？

- receiver: 'frontend-pager'
group_by: [product, environment]
matchers:
- team="frontend"

我认为"webhook receiver"可以帮助您。更多信息可以参考文档https://prometheus.io/docs/alerting/latest/configuration/#webhook_config

这是一个基于blackbox_exporter的度量抓取创建的webhook警报示例。

1. 普罗米修斯规则设置

您需要创建触发警报的规则，例如在此处定义了一个名为"http_health_alert"的规则。

groups:
- name: http
rules:
- alert: http_health_alert
expr:  probe_success == 0 
for: 3m
labels:
type: http_health
annotations:
description: Health check for {{$labels.instance}} is down

2. 警报管理器设置

'match'设置为http_health_alert，则警报将发送到http://example.com/alert/receiver'通过HTTP/POST方法(我想你会提前准备的(。警报将向配置的终结点发布JSON格式"http://example.com/alert/receiver"。您还可以针对不同的标签内容在端点/程序中自定义不同的接收方法或接收信息。

global:
route:
group_by: [alertname, env]
group_wait: 30s
group_interval: 3m
repeat_interval: 1h
routes:
- match:
alertname: http_health_alert
group_by: [alertname, env]
group_wait: 30s
group_interval: 3m
repeat_interval: 1h
receiver: webhook_receiver
receivers:
- name: webhook_receiver
webhook_configs:
- send_resolved: true
url: http://example.com/alert/receiver
- name: other_receiver
email_configs:
- send_resolved: true
to: xx
from: xxx
