Incident management rate limits (ULTIMATE SELF)

Introduced in GitLab 12.5.

You can limit the number of inbound alerts for incidents that can be created in a period of time. The inbound incident management alert limit can help prevent overloading your incident responders by reducing the number of alerts or duplicate issues.

As an example, if you set a limit of 10 requests every 60 seconds, and 11 requests are sent to an alert integration endpoint within one minute, the eleventh request is blocked. Access to the endpoint is allowed again after one minute.

This limit is:

• Applied independently per project.
• Not applied per IP address.
• Disabled by default.

Requests that exceed the limit are logged into auth.log.
