The reason the sysload graph doesn't reflect packets is because it
is activated early, before the ethernet card is activated. The
graph's namespace does not include an active view of the network
devices. Took me a little while to puzzle that one out :-(
Aha. Didn't realize that was the question.
It's not namespace but rather that the stats
file doesn't exist until a connection has been
established.
Look in stats.c:/^initmach:
snprint(buf, sizeof buf, "%s/net/ether0/0/stats", mpt);
m->etherfd = open(buf, OREAD);
before these two lines add
/* open ether0/clone so ether0/0 exists */
snprint(buf, sizeof buf, "%s/net/ether0/clone", mpt);
close(open(buf, OREAD));
and you won't have the problem anymore.
