We have statseeker as well, but we also use free open source tool smokeping.
See: http://smokeping.ucsc.edu
Pick ICMP from the menu on the left and then, perhaps, Resnet Switches
One of my favorite low cost deployable smokeping target is a small NAT
router.
Many network switches have instrinsic jitter in their response time
which partially
obscures sensitivity to the jitter seen by users. If your NAT router is
also a WiFi
access point, remove the antennas so it's not bothered by radio noise.

It is proving difficult to track down and we've been looking for some network traffic testing software to help out. Do you know of any good tools that can write pings to a graph, record latency, or anything that could help track down bottlenecks and dropped packets?
