Introduction
Purpose
In CloudStack, we have features like Alerts and Events that helps administrator in managing the cloud. Admin can get a list of Alerts and Events but there is no way to control them i.e delete or archive them.
This feature will provide the functionality to delete or archive the Alerts/Events. In this way admin can get more controls over the Alerts and Events and manage them to get required and useful information. CloudStack admin can manage them by using the APIs or through CloudStack UI. This is a functional specification of feature "Ability to delete/archive Events and Alerts" which has Jira ID CLOUDSTACK-874
