How do I get reporting data for dates in the past when I create a new custom report?

Matomo Cloud: By default, historical data processing is limited to the last 13 months up to the date the report was created. The configuration below does not apply to Matomo Cloud.

Matomo On-Premise: By default, when you create a new custom report, Matomo processes historical data for the last six months (available since Matomo 4). On-premise users can customise these settings by modifying the config.ini.php file.

For more details please see our guide here: How do I see historical data for a new Custom Report?

To collect data beyond the period configured in your config.ini.php file, you can:

1. Invalidate the historical data, and

2. Then re-process the reports for all your websites. If you have setup auto-archiving then the command to re-process the reports will automatically run within the next hour or so. Alternatively you can manually re-process the reports. Depending on the amount of data in your Matomo, this command may take a while to run and you may want to adjust the amount of days (and seconds) you want to reprocess.
