ID: 15959 Title: ntop_alerts: populate alert type dropdown list in alerts dashboards Component: cmc Level: 3 Class: Bug fix Version: 2.3.0b1 This werk fixes an issue with the alert type dropdown menu in the alerts dashboards. Previously, it was only populated with All, meaning you couldn't filter the alerts on alert type. Now the dropdown is populated with all possible alert type values.
