Frequently asked questions about alert notification methods, including webhook configuration, DingTalk and Lark bot signatures, and dynamic notification routing.
How do I configure an IP address allowlist for a custom webhook?
You can configure an IP address allowlist or specify an HTTP header to verify access permissions for a custom webhook. For more information, see How do I verify access permissions?
Only the alerting feature of the new version allows you to configure IP address allowlists for custom webhooks.
Can I specify signatures in the security settings of a DingTalk chatbot?
Yes. You can specify a signature in the security settings of a DingTalk chatbot or a Lark bot. For more information, see Webhook security settings.
How do I use different notification methods to send alert notifications by alert?
Use the dynamic distribution feature or the dynamic recipient feature to route alert notifications to different channels on a per-alert basis.
-
Dynamic distribution
If conditions are simple and all recipient information is already configured in the Simple Log Service alerting system, use dynamic distribution in an action policy. For more information, see Manage methods to send alert notifications.
-
Dynamic recipient
If conditions are complex, such as when recipient information must be parsed from logs or retrieved from a third-party user management system, use the dynamic recipient feature. For more information, see Configure dynamic recipients.
What do I do if an alert is triggered but alert notifications fail to be sent?
For causes and solutions, see Error codes.
