Your managed metrics storage database is part of Historical data logging. It's a database solely for your logged machine data. Over time, its storage may gradually fill up, leaving you with the option to either upgrade to a larger database or delete old data that you're no longer interested in. This article explains how you can permanently delete logged data.

1. Go to Fleet Manager > Devices and click on your device name.
2. In the left menu, go to Data sources.
3. Click on the data source whose data you would like to delete.
4. Go to Tags and select Remove data points in the top right corner.
5. Select a date.
   • Data from all data tags from this data source that was logged before the selected date will be deleted.
   • Data that was logged after the selected data will not be deleted. That data will remain available.
6. If you are sure about the selected date, click Remove.
   • Data will be removed in chunks. It may take some time before the data is permanently deleted. This depends on the amount of data, so no general estimation can be provided.
   • It is not possible to easily see if the data deletion is still in progress. Simply check one of your historical data components to see if there is still data before the selected date. If there is, the data deletion is still in progress.
   • After the data has been deleted, it may take some time before the data storage usage for the remaining data is updated at Admin > Usage. This depends on the amount of data, so no general estimation can be provided.
   • Only one data removal action can be active per data source. Please wait for the previous one to finish before starting a new data removal.
