Is there any way to estimae, or even check out the amount of data up- and downloaded through IPFS in a given time period? I’m interested in the periodic changes in traffic, especially since the existence of DTube.
For your node or the entire network? For your node, you can call
ipfs bitswap stat to see how much data you’re sending/receiving via bitswap. If you want a more general bandwidth usage metric (including bookeeping data and data sent via other protocols like the DHT), you can call
ipfs stats bw.
