Apologies for shortage of info in original question.
1> netstat -k is undocumented.
2> the first_collision field appears to only be present for
the hme interfaces and under 2.5.1.
What I needed:
I have about 60 Ultra E3/4/5/6000s. The Ultra's ship without
le0, just the hme0. Plus each machine has an additional 3 hme's.
The site is an ISP so with HA running, the networking gets a
little scary. We felt that a register of second collisions
vs. the total would better gauge the load on the various
segements, an option which is available under HP-UX and AIX.
All I could find was this first_collision field reported
by netstat -k, but was unaware what the number represented
and/or if there was a command I didn't know of to extract
the needed info.
email@example.com (perl script to compute %)
the le interface will only report one collision, then retry 16 times,
and then report another
the qe interface reports all
only hme reports "first-collissions" but that count can be 0 even
if collisions aren't. So I have no idea what they are.
Here is a small sample of what we get;
# ifconfig -a
lo0: flags=849<UP,LOOPBACK,RUNNING,MULTICAST> mtu 8232
inet 127.0.0.1 netmask ff000000
hme0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 1500

So if you read this far, yes, I still dont know.
