Tracking Down Blips

Wonder who (or what) is hogging your bandwidth? Install a network monitor.

In a previous article, I explained the process for setting up Cacti, which is a great program for graphing just about anything (see the November 2016 issue). One of the main things I graph is my internet usage. And, it’s great information to have, until there is internet activity you can’t explain. In my case, there was a “blip” every 20 minutes or so that would use about 4mbps of bandwidth (Figure 1). In the grand scheme of things, it wasn’t a big deal, because my connection is 60mbps down. Still, it was driving me crazy. I don’t like the idea of something on my network doing things on the internet without my knowledge. So, the hunt began.
