Ignition Edge Historian - history clearance

I'm looking to clear the all history in Ignition Edge Gateway, is this possible? If so, how?

I have a bunch of data throughout the development of a project that needs to be cleared out!

You can delete the edge historian IDB file on disk, in the data directory of your Ignition install. Tread carefully, but it should be pretty clearly labeled. Exact path and filename will vary by your Ignition version.

Are either of the following more savory:

  • Backup, uninstall / reinstall, restore?
  • Connect with sqllite and delete old entries with a sql query?

Thanks! This would be a great feature addition :slight_smile:

Shutting down the gateway and deleting the file is going to achieve the same end result as either of those steps, and be faster and harder to mess up :man_shrugging:

Dealer's choice.
