Application Real-Time Monitoring Service:Format of alert notifications sent by using webhooks

Limits

When you create a webhook in ARMS to send alert notifications, take note of the following limits:

• Content-Type must be set to application/json.

• You cannot use the $content field together with the $alertmanager_content field. If you attempt to do so, the $content field does not take effect.

• When you test a webhook in the ARMS console, you cannot replace the $alertmanager_content field.

  For more information about how to use a webhook to send alert notifications, see Use a webhook to send custom alert notifications.

Format of alert notifications

The following section describes the format of open-source Alertmanager. ARMS sends webhook-based alert notifications in this format. For more information, see the Prometheus documentation.
