I've been using vnStat to monitor the ethernet interface on a Linux computer, but found that it includes all local traffic. I do many file transfers from within the subnet which far exceeds the Internet traffic, so I'm having trouble getting any long-term and accurate monitoring of Internet usage due to this.I'm hoping to find a way to exclude any local traffic and just count the external (Internet) traffic for the past hour, day, and month.The computer is headless and accessed over SSH, so only command-line tools can be used.I also tried darkstat which allowed me to filter the traffic, but it only provided a web interface.Any ideas on how I can achieve this? Any suggestions will be very much appreciated!EDITI've been thinking outside the square a bit and found a messy solution.I looked at the HTML source that darkstat was generating and found that the graphs use an XML file. I was able to view this from command-line using curl:curl 127.0.0.1:667/graphs.xmlThis gives me an XML document with all the chart series data. I could parse this and create something a bit more readable. This method seems inefficient and overly complicated though.Surely there's a nicer way! Any advice is appreciated.
Program like vnStat that filters for only external (Internet) traffic
