My mail PFY tells me that my original send of this message never made it
through.... so here's the resend (a thread regarding Net-SNMP 5.4 +
OpenBSD 4.1 + PF-MIB).

Indeed. My patch doesn't touch anything like that. I also don't have
this issue:
UCD-SNMP-MIB::laLoad.1 = STRING: 0.07
UCD-SNMP-MIB::laLoad.2 = STRING: 0.10
UCD-SNMP-MIB::laLoad.3 = STRING: 0.08

I've had a patched snmpd running on a few 4.1 machines for many weeks
now, no issues. Before that it ran on 4.0 without issue.

If you're having issues, please provide information like 1) the output
you're seeing, 2) how to reproduce the issue, 3) the commands you're
running, etc.
I appreciate everyones interest in my little project.

Oh god please yes!
I'm working on pfsync and a general "OPENBSD-NETSTAT-MIB" for feeding
"netstat -s" stats into a MIB.
I've also written a small Nagios plugin that uses the Net-SNMP bindings
to walk the CARP Interface Status Table
("OPENBSD-CARP-MIB::carpIfTable") to check for proper active/standby
configs:
http://www.nagiosexchange.org/Networking.53.0.html?&tx_netnagext_pi1[p_view]=1021
There's also a check_pf:
http://www.nagiosexchange.org/Networking.53.0.html?&tx_netnagext_pi1[p_view]=895
Also, I'm hoping to switch one of or lab policy routers back to pf(4)
this weekend, and I'll be able to improve my OBENBSD-PF-MIB MRTG
Templates and upload them (*hopefully*) to:
http://howto.aphroland.org/HOWTO/MRTG//
Which seems to be the definitive MRTG Template/OID Reference (if such a
place exists -- MRTG is almost 10 years old and that idea never occurred
to anyone), but the site has been unresponsive as of late.
Might be time for a separate Wiki.

Looks like I spoke too soon. We hadn't had any problems with this MIB
but as I was investigating it a little bit more deeply, I uncovered
some problems:
1) CPU utilization (system, user, idle) is always reported as 0.00%,
regardless of actual utilization. This is probably a flaw in
net-snmp, not Joel's patch.
2) I've never used Joel's CARP MIB stuff, so I never looked at it
closely. Now that I look, it seems that it's not returning the objects
that show the CARP status of my interfaces. I'm running straight-up
OpenBSD 4.1.
3) snmpd(8) died after I ran a bunch of snmpwalk(1)'s against it. Not
sure what's going on here.
Has anybody else encountered these problems? I'm going to work on #1
but I'm afraid that #2 and #3 are probably beyond my limited C skills.

Hi,
Has anybody considered merging Joel Knight's OpenBSD SNMP MIB work
into ports/net-snmp? His patch works great and has been in production
here at Backcountry.com for six months now. OpenBSD probably will
want it's own enterprise number, too.
I'm willing to lend a hand, if it's needed.
Thanks,
Chris
