Get the best of both tools and use mtr (assuming unix-like platform).
There are similar tools for windows (pingplotter?).
This thread reminds me of my own DSL, which rides the ILEC's network and
is handed off to $work at the CO as an ATM PVC. For years, my DSL service
has osciliated from fine (20-30ms ping times) to not good (200-300ms) to
unusable (>=1000ms ping times). It seems to work fine for months, then
get bad to really bad for days or weeks at a time. I've replaced CPE
several times, and even keep 2 totally different brand/model routers at
the house, just in case (so when I call the DSG, I can say "yes, not only
have I power cycled it, I've replaced the router"). I've spent
considerable time on the phone with the ILEC. Most calls, they claim
there's nothing wrong. A few times, they've admitted it's a known problem
with the "lt card", not that that means much to me, and resetting it often
makes things better.
