To see the difference between traceroute and rtt's for multiple days , we developed traceroute archive. It can be accessed using 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 traceroute and shows the changes observed in a link for the requested days. It is currently available from 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
Traceroute Archive Flow At SLAC
Following are scripts used for traceroute archive
?1. Collection of Traceroutes
1.1 autotrace.pl
This script can be found at /afs/slac/package/pinger/autotrace.pl. It saves traceroutes from all SLAC Pinger nodes to its monitored sites and runs as cron job once everyday.
Input = http://www-wanmon.slac.stanford.edu/cgi-bin/nph-traceroute.pl?target=www.fapesp.br
Output = it is saved in /afs/slac/package/pinger/chktrace/2011_08_24/www-wanmon.slac.stanford.edu_to_www.ab.kg_2011_08_28 as :

Traceroutes of all the nodes for a day are collected in date folders.
2. Display of traceroutes
2.1 traceroutearchive.cgi
This script is placed at /afs/slac.stanford.edu/g/www/cgi-wrap-bin/net/offsite_mon.
Example is
Note:
Difference is counted as per IP name and IP number(RTTs are excluded) between any two traceroutes.
