Crons imposes a rate limit on check-ins to prevent abuse and resource overuse. Specifically, you can only send a maximum of 6 check-ins per minute per existing monitor environment. This limit is enforced on a per-project basis, meaning that the rate limit applies collectively to all monitor environments within a given project. You can check if any of your check-ins are being dropped in the Usage Stats page.
To avoid dropped check-ins, it is crucial to manage and distribute your check-ins efficiently within the rate limits. This will help maintain accurate monitoring and ensure that all critical check-ins are captured and processed.
