I was wondering how I would go about measuring the traffic being used on my network for the bitcoind node I am running. It's running on the standard 8333 port, using linux as the OS.
I was looking at iftop which seems to be a tool for doing what I want to do, but I am specifically looking to only monitor traffic associated with the bitcoind node.
Basically I'm trying to see if my implementation of a QOS for the node is working properly.
The RPC interface has a command getpeerinfo which will give a breakdown of upload and download metrics per connected peer.
{
..
"bytessent": 67619177,
"bytesrecv": 47229533,
"conntime": 1446238156,
..
}
Totals for the session for all peers are available with getnettotals.
{
"totalbytesrecv": 3664310320,
"totalbytessent": 619085268,
"timemillis": 1446521403149
}
vnstatis an external tool which will do system-wide monitoring and statistics collection over extremely long time periods. There is no per process breakdown, but it's a good thing to have around for a global view anyway.
