You can create a custom alarm view for alarm filters in USM to provide quick views into specific data. For example, you can create an alarm filter that shows only disk alarms at or above critical or that shows only alarms with certain hostname components.
In addition, you can create a portlet that automatically shows an alarm view with a preloaded filter so that different users see different alarm views on startup.
To support multi-tenancy, you can see and can take action only on alarms from your origin. Authorized users can edit the Access Control List (ACL) to restrict further which alarms users can see.
