I'm writing a plugin for munin to monitor my monthly bandwidth usage. Comcast has a "250GB" cap in place, that I've blown through 4 out of the last 5 months. June was 346GB according to Comcast. The second day of July and I've already used 4% of my cap.
The plugin looks at my outside facing interface, adds upstream and downstream bytes together and divides by the uptime. This gives me bandwidth usage for a daily and a monthly average and let's me look at see what direction it's trending. My question. ifconfig provides bandwidth in bytes and normally I'd just multiply by 8 and get bits and be done with it. However Comcast in their infinite wisdom has decided to display the "bandwidth" usage in bytes too. So I really want to show "bandwidth" in bytes so I'm looking at apples. There is a scaling value in munin if you are looking at memory or traffic you can stipulate 1000 or 1024 as the multiple. I'm leaning towards using the 1024 value to show bytes, but it just seems "wrong".
