Clear Old Records on DB?

Clear Old Records on DB?

Hi,
when I add a new monitor, if the IP or hostname was recorded before but not in use,
appmanaged is confused, in host name section old monitor name seems,
is there easy way to clear all old monitor records in database,
or delete old monitor records in tables manually, (dbo.AM_ManagedObject, dbo.IpAddress, .dbo.ManagedObject)
