I know you can see what applications are using how much data in a given period of time by going to Start -> Settings -> Network & Internet -> Data Usage, then clicking the Usage Details option to bring up a list.
Does anyone know if there's a way to output this list at the command line or from powershell?
You can execute Netstat -e -s command displays Ethernet statistics.
You can also execute Get-NetAdapterStatistics powershell command to gather network adapter statistics. It provides a quick overview of the sent and received packets.
You are looking for the per-app total data usage, correct?
I haven't found a way to directly get the cumulative data - it doesn't appear that MS exposes any interfaces to access the data usage info. There are tools that can parse the database and get the hourly data values - NetworkUsageView . Then you can do some post-processing on the .csv to add up all the entries for each app.
Thanks for the suggestions. I have someone asking me to pull the information about "what apps used all their data this month?" for a list of computers. I was hoping for a way to pull that list out without having to remote in to a given computer. Ah well. I'll keep digging but it looks like there isn't an easy way to do what I was asked to do.
