7.3. 添加 Alertmanager Webhook

7.3. 添加 Alertmanager Webhook

您可以向现有 Alertmanager 配置添加新 webhook，以接收有关存储集群运行状况的实时警报。您必须启用传入的 webhook，以允许将消息异步到第三方应用程序中。

例如，如果一个 OSD 在 Red Hat Ceph Storage 集群中停机，您可以将 Alertmanager 配置为在 Google chat 上发送通知。

前提条件

正在运行的 Red Hat Ceph Storage 集群启用了监控堆栈组件。
在接收第三方应用程序上配置的传入 Webhook。

流程

将 Alertmanager 配置为使用 Webhook 进行通知：

语法

service_type: alertmanager
spec:
  user_data:
    default_webhook_urls:
    - "_URLS_"

service_type: alertmanager
spec:
  user_data:
    default_webhook_urls:
    - "_URLS_"

Copy to Clipboard

Toggle word wrap

default_webhook_urls 是添加到默认接收器 webhook_configs 配置中的额外 URL 列表。

示例

service_type: alertmanager
spec:
  user_data:
    webhook_configs:
    - url: 'http:127.0.0.10:8080'

service_type: alertmanager
spec:
  user_data:
    webhook_configs:
    - url: 'http:127.0.0.10:8080'

Copy to Clipboard

Toggle word wrap

更新 Alertmanager 配置：

示例

[ceph: root@host01 /]#  ceph orch reconfig alertmanager

[ceph: root@host01 /]#  ceph orch reconfig alertmanager

Copy to Clipboard

Toggle word wrap

验证

从 Alertmanager 到 Gchat 的通知示例：
