Yes, we automatically set the creation date of a Roll-Up to the creation date of the oldest source website. This way you can view reports in the past for a Roll-Up.
If you are not seeing historical reports for your Roll-Up, please check the following:
- Go to “Administration => General Settings” as a super user and check that the setting “RollUp Reporting => Synchronize creation date” is enabled.
- Then check how your Matomo reports are processed. What we recommend is to setup the cron archiver core:archive. Once you create this crontab entry, it should also process all your historical reports for the Rollups after the crontab is executed the first time.
- Then if you are still not seeing your historical data for your Roll-Up(s), try to force process all historical data, by first invalidating the data you want reprocessed and then running this command:
./console core:archive --force-all-websites --url=YOUR_MATOMO_URL_HERE
(or if you are using Matomo 3.x, run the following command:
./console core:archive --force-all-websites --force-all-periods=315576000 --force-date-last-n=1000 --url=YOUR_MATOMO_URL_HERE)
