The subject line says it all. I want to create a monthly report that will show me the bandwidth utilization for every port in a switch. I was able to put together reports for my core switches by manually adding each and every interface in a custom report, but that was horrendously tedious. I'm hoping someone has a script or query or magic beans that will just create this sort of report. I have multiple Cisco 4506E switches with hundred of ports that plug into hundreds of physical servers, and creating those sorts of reports would take the rest of my life.
The report should be in graph form; I don't need a table report, but if someone has a pre-existing script that generates tables, I can live with that or modify it myself. I've tried searching Thwack but I can't seem to find what I am looking for. Thanks for your help!
