I wrote a Perl script using SNMP to collect data from
cisco RPING probes. It is storing and visualizing it later
using RRD libraries.
I am perfectly aware that ICMP echo is not really an efficient
way to measure network latency. It is rather 'IOS kernel ICMP
response' latency monitor.... I had no time to use SAA yet,
which is probably better.
If you are interested in my script drop me a note and I will
forward it to you.

Subject: Measuring PoP to PoP latency--tools to use?
What tools exist that will periodically log into multiple routers and run
ping tests
to various destinations and then record the results in graphical form?
I am trying to avoid writing an expect script to do this.
I want to set up something that records semi-live data to produce
a web page similar to:
http://ipnetwork.bgtmo.ip.att.net/current_network_performance.shtml
The map portion of the graphic may be too fancy. A simple grid similar to
this
might be better:
http://www.internethealthreport.com
Any suggestions as to what tools to investigate would be greatly
appreciated.
I browsed the nanog archives as well as google...no hits so far.
Thanks,
BM
