    Application Real-Time Monitoring Service:Webhook alert format

    Last Updated:Jun 20, 2026

    Configuring a webhook's notification template allows Application Real-Time Monitoring Service (ARMS) to send alert content in the open-source Alertmanager format.

    Limitations

    Note the following limitations when using a webhook for custom alert notifications:

    • The Content-Type must be application/json.

    • Cannot be used with the $content field. If you use $alertmanager_content, $content does not take effect.

    • The webhook test feature in the ARMS console cannot test the replacement of $alertmanager_content.

    For setup instructions, see Customize alert notifications by using a webhook.

    Alert payload format

    ARMS sends alert payloads to your webhook in the open-source Alertmanager format, as shown in the following example. For more information, see the official Prometheus documentation.
