alertmanager

测试

curl -X POST http://localhost:9093/api/v2/alerts \
  -H "Content-Type: application/json" \
  -d '[{
    "labels": {
      "alertname": "HighCPU",
      "instance": "server1:9100",
      "severity": "critical"
    },
    "annotations": {
      "description": "CPU usage超过95%"
    },
    "startsAt": "2023-07-20T12:00:00Z"
  }]'

route:
  receiver: 'webhook'
  
receivers:
- name: 'webhook'
  webhook_configs:
  - url: 'http://localhost:5000/alert'  # 自定义Webhook接收地址
    send_resolved: true                   # 发送恢复通知
    # http_config:
    #   bearer_token: 'your-auth-token'     # 可选认证
    max_alerts: 10                        # 单次请求最大告警数

Alertmanager 会将相同标签的告警合并为一个通知组，默认 group_wait: 30s（首次等待）和 group_interval: 5m（重复间隔）

route:
  receiver: 'webhook'
  group_by: ['alertname']  # 按告警名称分组
  group_wait: 1s          # 立即发送首次告警
  group_interval: 1s      # 每组告警间隔1秒
  repeat_interval: 1s     # 相同告警重复间隔

receivers:
- name: 'webhook'
  webhook_configs:
  - url: 'http://localhost:5000/alert'
    send_resolved: true
    max_alerts: 10
