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 every 30 minutes and whenever you update your settings.
This option allows you to resolve all active items whenever you report a deploy.
