git daemon inetd mode: need traffic statistics

Has anybody got patchsets that let git-daemon send traffic data (to syslog) at the end of each request, about the peer, and how many bytes in each direction?

Hoping somebody has something useful to share that isn't coming up in my research.

Gentoo's seeing a big uptick in usage on the anonymous git daemons via xinetd (we do offer HTTP/HTTPS as well, but the growth is in http).

I know it's via the git/9418 protocol because the HTTP traffic is well-metered and hasn't grown, and the overall traffic to the hosts also grew. This is confirmed by using Netflow data, which tells me it's the Git port, and some of the IPs, but doesn't let me get which repo directly (And processing the netflow data is also painful).
