Component : IM Reporting / Admin / Configuration
Scheduled reports from basic requirements were to get summary report across a day or more,
So no provisions were made in feature to schedule same report within less than 24 hour period.
In this scenario would need to schedule a daily report to run for the "last hour" for every hour that you want to report in a given day.
In order to truly get an hourly report for a given page for every hour of the day, you would need to create 24 scheduled reports to get complete coverage.
