Getting guest network counters?

[bifrost]

I'm trying to dig out the network statistics per vm, and I'm having a hard time doing in in what
seems like an elegant way.

I can use VBoxManage to do it:
# VBoxManage debugvm vmXX statistics --pattern "/Devices/E1k0/*"
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Statistics>
<Counter c="7647617911" unit="bytes" name="/Devices/E1k0/ReceiveBytes"/>
<Counter c="191139299809" unit="bytes" name="/Devices/E1k0/TransmitBytes"/>
</Statistics>

However, that seems kinda clunky, and I need to know to decypher the network interface name beforehand.
I looked into using vboxshell to see if that would give me an idea how to use the API for this, but it doesn't
seem to report the details. The API does have some documented access for some statistics, but they're not network statistics.

I've googled, but there's not much to report...

any ideas?

I did this in my GNS3 Network Simulator code (in VBoxPython), see screenshot:

in general you need to get the bytes, as you did, then MAC addresses to match the vNICs.
