Anyone got a good working mail-notification-profile on disk space use ONLY. eg. like over 90%.
Problem is,  you have to use(afaik) 'violate any threshold value' so you get an mail for ANY violation.

We had to start filtering at our mail system,  dropping all but those concerning disk space.

Then we process incoming mail in our separate-eventsystem to create disk-event-workorder.  Can easily put unnecessary load on our systems.
