First thank you for your reply Michele, SANET sounds interesting,
and I'll definitely take a look at it.

My view for defaults is, if users device has BGP neighbours, vastly larger
amount of users want them to be monitored than not, so my sane default
would then to have feature default on.

Also monitoring BGP is not just up/down, but also amount of prefixes
received, of course amount of people care about this, is lot smaller than
those who care about up/down, but SP's care.

As you explained that at the moment is is rather chore to setup the
program, I guess I'll wait for the more official launch. But I'll
definitely take a look at it, and will commit something back, if I'll use
it. Thanks.

One way could be, that you project current number with average change from
last n hours|days|weeks|months and see if projected number hits limit
within n hours|days|weeks|months.

One of the boxes in my zenoss quick demo had more interfaces, and the 20
boxes were just few I chose for the demo. I have no trouble buying more
boxes to handle all the devices I'd need to, but I'd hope single server
could cope with bit higher number than 20 boxes.
