I work for an ISP in southeastern Oklahoma, One day the owner wanted to know the percentages of users connected at a certain carrier speeds. So him and I started working on a perl script that would do this job. What we did is setup a perl script that would snmpwalk every Lucent Portmaster we had and tally up the results and build the graph. I also added the percent of totally port utilization with the black line on the graph. As we found out less than 50% of our users do not connect at v.90 speeds. I love rrdtool I write all of my rrdtool probes in perl and use all the perl bindings the add/build/update/graph... Its really quite easy once I realized how it worked. MRTG was easy to learn but rrdtool was a totally different ball game.

The Script for those who care
