Yes, there is a version of Status Meter that you can use and download through the link posted below, but it will be useless, because you want to monitor all the devices which would mean that the application should be install on each device, therefore not possible since Status Meter is available only for 2 platforms.
All the devices need to be connected to an Internet source and Status Meter won't track all the traffic if it's installed only on one. What I am saying is that you need to have the app on a PC and all the devices need to be connected to that PC in order to track everything.
Some Internet Service Provides have the statistics when you log-in to your member's area on their website. You can see there all the traffic or you need a router to connect all the devices to in order to monitor network traffic.
