This sounds like more of an eHealth function.  Spectrum does a pretty good job 
of knowing what the state of the world is right now, but it has a very short 
attention span.  It doesn't do well with what things were like a few minutes 
ago.  You can monitor traffic changes, to a reasonable extent, in eHealth 
though.

Subject: [spectrum] Spectrum Watch for % variation in traffic use

Hi
Just delving into Watches and am perfectly happy with simply polling attribute 
watches however I am looking for a pointer or two with relation to a new watch 
I need to create
Its a fairly simple on - I need a watch that shows traffic variation use on a 
port (both in and out) over 2 or more readings
Initially looking for a 10% drop in traffic  (as a test) over a 5 minute 
polling cycle - with maybe an option to say only alert if 2 polling cycles both 
have a 10% drop in traffic

Any pointers appreciated
