To see the difference between the traceroute and rtt's for multiple days , we developed the traceroute archive. It can be accessed using teh the traceroutearchive.cgi script. It displays traceroute from a monitor node to monitoring a monitored node for any three days (which can be selected from a drop down menu). It checks loops within the traceroute and shows the changes observed in a link for the requested days. It is currently available from 5 PingER monitors including SLAC to world wide nodes monitored by SLAC at http://www-wanmon.slac.stanford.edu/cgi-wrap/traceroutearchive.cgi

This script can be found at /afs/slac/package/pinger/autotrace.pl. It saves all traceroutes from the SLAC Pinger nodes to its monitored sites and runs as cron job cronjob once everyday every day on pinger.slac,stanford.edu under user pinger..
It uses : for example http://www-wanmon.slac.stanford.edu/cgi-bin/nph-traceroute.pl?target=www.fapesp.br to make the traceroute
It gets the list of hosts to traceroute to by using wget and pingtable.pl.
Output iis is saved in /afs/slac/package/pinger/chktrace/2011_08_24/www-wanmon.slac.stanford.edu_to_www.ab.kg_2011_08_28 as :
