>Description:
Hi
I've recently switched my DomU servers from Debian Linux to NetBSD 6.0. I monitor my servers with cacti and snmp and have few problems with monitoring cpu load. I've installed net-snmp using pkgin from binary packages on a fresh NetBSD 6.0 DomU install.

Cacti monitors load on only one cpu because there is no instance of hrProcessorLoad.769 as you can see from snmpwalk:

HOST-RESOURCES-MIB::hrProcessorFrwID.768 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.769 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.768 = INTEGER: 1

DomU correctly detects both CPUs:
vcpu0 at hypervisor0: Quad-Core AMD Opteron(tm) Processor 2352, id 0x100f23
vcpu1 at hypervisor0: Quad-Core AMD Opteron(tm) Processor 2352, id 0x100f23

also "top" reports both CPUs present. 

Any help? I'm not a coder myself but if you point me in the right direction I'll try to debug and maybe fix it myself.


>How-To-Repeat:
Install NetBSD 6.0, net-snmp from binary packages from 2012Q3 using pkgin and try to monitor cpu load on every CPU.

 Hi, I've added 2 more cpus to the DomU (4 CPUs total) and the problem
 persists. Cpus are listed in snmp but the load is reported only for the
 first cpu id. Other cpu ids OIDs are not even generated.

 Hi, I've just upgraded to pkgsrc 2013Q1 and this bug is still not
 resolved. I don't see any load on any processor now. Also I've got lots of:

 Apr  3 19:33:03 test snmpd[1478]: sysctl vm.bufmem failed (errno 12)

 which prevents me from monitoring memory usage through snmp.

 What's the point of releasing next pkgsrc relase and bumping up the
 version of snmpd if one doesn't resolve any PRs?

 Now I've got 8 CPUS total:
 HOST-RESOURCES-MIB::hrProcessorFrwID.196608 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196609 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196610 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196611 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196612 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196613 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196614 = OID: SNMPv2-SMI::zeroDotZero
 HOST-RESOURCES-MIB::hrProcessorFrwID.196615 = OID: SNMPv2-SMI::zeroDotZero

 but the CPU usage is represented only for the first one:

 HOST-RESOURCES-MIB::hrProcessorLoad.196608 = INTEGER: 1

 And the discussion about vm.bufmem failed (errno 12) in logs is here:
 http://mail-index.netbsd.org/netbsd-users/2013/01/02/msg012263.html

 where Jean-Yves Moulin said he sent a patch to the maintainer. Why such
 a simple patch couldn't have been included in the next stable release of
 pkgsrc?

 PS. those two bugs exist on 6.0, 6.0.1, 6.1_RC1 and 6.1_RC2
