To see the difference between the traceroute and rtt's for multiple days , we developed the traceroute archive. It can be accessed using teh traceroutearchive.cgi script. It displays traceroute from a monitor node to the monitoring node for any three days (which can be selected from drop down menu). It checks loops within within the traceroute and shows the changes observed in a link for the requested days. It is currently available from the SLAC to world wide nodes monitored by SLAC at http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi and also from pingER Seecs to all monitored sites within Pakistan at http://pinger.seecs.edu.pk/cgi-bin/traceroutearchive.cgi

Following are scripts used for the traceroute archive

This script can be found at /afs/slac/package/pinger/autotrace.pl. It saves all traceroutes from all the SLAC Pinger nodes to its monitored sites and runs as cron job once everyday.
