[j-nsp] monitor interface rate

[harbor235]

To all,

I would like to monitor a juniper router interface via snmp, simple enough.
However, I do not want bps, I want to monitor the interface as a percentage
of it's total capacity. In the end I want to be notified if my interface
exceeds 70%
of capacity so I can initiate capacity management planning.

I know I can on an interface by interface basis figure out 70% and program
that into
each interface collection, however, that does not scale. Is there anyone out
there
that knows of a MIB obect that does this?

thanx,

Mike
