Set Up Crons
Sentry Crons allows you to monitor the uptime and performance of any scheduled, recurring job in your application.
Once implemented, it'll allow you to get alerts and metrics to help you solve errors, detect timeouts, and prevent disruptions to your service.
- Use our getting started guide to install and configure the Sentry SDK (version
7.51.1or newer) for your recurring job. - Create and configure your first Monitor.
When your recurring job fails to check in (missed), runs beyond its configured maximum runtime (failed), or manually reports a failure, Sentry will create an error event with a tag to your monitor.
To receive alerts about these events:
- Navigate to Alerts in the sidebar.
- Create a new alert and select "Issues" under "Errors" as the alert type.
- Configure your alert and define a filter match to use:
The event's tags match {key} {match} {value}.
Example: The event's tags match monitor.slug equals my-monitor-slug-here

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.
