To view the execution details of Scheduled Events within the application, Mendix provides a built-in system entity called ScheduledEventInformation. This entity stores information such as the scheduled event name, start time, end time, and status. In Studio Pro, if you use Find Usage on this entity, you will usually find an existing page in most projects. Make sure this page is accessible via navigation for an admin role; from there, you can easily review when scheduled events ran and whether they ended with errors, and filter by status if needed.

To check the configuration of Scheduled Events and understand when they are supposed to run, Studio Pro is the most reliable place. You can review all SCEs under the 'Scheduled events' section in the App Explorer. Alternatively, in the Studio Pro, you can use Edit -> Find Advanced -> Search for: Documents, Document type: Scheduled Event to quickly list all scheduled events in the project.

To manage which scheduled events are enabled or disabled per environment (Dev / Test / Prod), you should use the Sprintr / Mendix Cloud Portal. However, the Cloud Portal only shows activation status and does not provide detailed schedules or execution history.

If you have the Administration Module installed, this provides a page with the details of all the executed Scheduled Events in your Mendix application. Add this to your Navigation, and make sure you assign the correct permissions to be able to access it.
