Looking at the adhoc performance reports we select an interface and then choose
which rrd's to graph for that interface. I often have a need to get a snapshot
of all data flows in a device. As such i would like to be able to quickly graph
all "bits in/out" rrds for all interfaces on a single device. Currently if i
wish to do this i have to create a brand new ksc report manually, which isn't
much fun if i have a 48 port switch... I'm aware that a device may well have
different data for different interfaces, but i'd assume that if we could
select "all" interfaces, the next screen would list all rrds that have been
collected for any interface. should an rrd not exist, that interface would be
ignored and not listed in the report.
