[Orca-users] RE: How many orca installations

[Allen Eastwood]

True.  One could either pull up the separate hosts in different browser
windows, or pull the RRD's from the hosts you wanted to compare and
generate those.

Typically, in my usage, we haven't needed to do this yet...not to say
that my boss won't come to me next week and decide he needs a new
report!  ;-p
