Hi Kolus, Please take a look at my RTT and packet loss percentage graphs at: http://haroon.sis.utoronto.ca/perl/rrd.cgi/network_stats/ Obviously my graphs are not the same as the one you described, but perhaps by looking at mine you will be able to get some more ideas. The front-end being used to display the graphs is rrd.cgi: http://haroon.sis.utoronto.ca/rrd/scripts/ The config file is at: http://haroon.sis.utoronto.ca/rrd/scripts/rrd-network.cfg Here are my DEFs and CDEFs: DEF:roundtrip=/www/htdocs/rrd/logs/network_stats/ping_internal.rrd:rtt:AVERAGE DEF:packetloss=/www/htdocs/rrd/logs/network_stats/ping_internal.rrd:pl:AVERAGE CDEF:NoPL=packetloss,10,LE,INF,UNKN,IF CDEF:25PL=packetloss,25,LE,packetloss,10,GT,INF,UNKN,IF,UNKN,IF CDEF:50PL=packetloss,50,LE,packetloss,25,GT,INF,UNKN,IF,UNKN,IF CDEF:75PL=packetloss,75,LE,packetloss,50,GT,INF,UNKN,IF,UNKN,IF CDEF:100PL=packetloss,100,LE,packetloss,75,GT,INF,UNKN,IF,UNKN,IF My graphs were inspired by Brandon Gant's at: http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/gallery/brandon-01.html Hope this helps. -- Haroon Rafique <[EMAIL PROTECTED]> -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
