You can configure Rollbar to automatically resolve active items to simplify your error management workflow. The options are set per environment, and can be found by going to Settings → Auto-Resolve in each of your projects.
This option will automatically resolve items if they have not occurred in a certain number of days. Items are checked for inactivity approximately every 30 minutes, and whenever you update your settings.
This option allows you to resolve all active items whenever you report a deploy.
