This should be possible with the basic threshold options. You have min and max threshold options, so set both for one interface say a max of 70% and a min of 10% and you will bet alarms when you go above the max 9and back below it) and below the min (and back above it)... I think that does what you want???

For instance, I use maximum threshold monitoring to catch when my circuits are above 80% utilization. I would also like to see when my circuits have large swings in utilization, which usually indicates something weird going on (DoS, another circuit failure, bad BGP announcements, device going down, etc). This is especially useful for those of us with huge traffic variances between peak and trough. A have interfaces that might be 75% utilized in the evening and only 5% utilized at 3am. I need something to catch large drops (or spikes) in traffic at peak without sending out false alerts every night. Has anyone written such a monitor, or is this something I need to put together on my own?
