I had posed this question to SW support. How can we make an interface not show up as a problem in the down interfaces page if if has been down for some amount of time. SW support gave me the following response. This solved our issue. Hopefully this helps someone else.
DATEDIFF(day, InterfaceLastChange, getdate()) = 0
With this filter, if the status of the interface did not change during the current day, then the interface will not appear in your resource.
You can modify to e.g.:
DATEDIFF(day, InterfaceLastChange, getdate()) = 1
and it will show the interfaces for which the status has changed yesterday or today etc...
If you modify it to e.g.:
DATEDIFF(week, InterfaceLastChange, getdate()) = 0
It will the interfaces for which the status has changed during the current week.
For more ideas have a look at the following link:
