Monitoring Dell Boxes via SNMP (CentOS 5.1 x86)

[Baird, Josh]

I have isolated this issue to a problem with a centosplus kernel.  Using
the normal el5 kernel corrected my problems.

 

Thanks,

 

Josh

Hi,

 

 

As you are running CentOS you could consider upgrading to net-snmp 5.4.1
(the rpm from fc8 or so will work fine as long as you rebuild it). It
fixes pretty much all issues I've had with Xen and net-snmp working
together. The default net-snmps from RedHat, due to various reasons, are
not really good (RHEL4 is still missing 64 bit interface counters, etc.)
for serious production use. The OMSAs will work okay with later net-snmp
versions and so do HP ASM SNMP daemons, too.

 

 

Kaj :)

Sorry if this might be a bit off-topic, as I am not sure it can be
isolated to Dell servers only.  I have seen this problem mentioned on
the list before, but there was no solution as far as I know, and it was
stated that it was only a problem with Xen kernels, which I am not
running.  I recently updated two CentOS 5.1 boxes (with yum update) last
week.  Ever since then, net-snmp seems to be crashing (net-snmp was not
updated). 

 

I can snmpwalk the device, and then snmpd will stop responding.  I see
these errors in messages:

 

Linux fc-netops 2.6.18-8.1.8.el5.centos.plus #1 SMP Mon Jul 16 08:49:50
EDT 2007 i686 i686 i386 GNU/Linux

 

Feb  4 03:15:27 fc-netops snmpd[24166]: NET-SNMP version 5.3.1

Feb  4 03:15:28 fc-netops snmpd[24166]: ipSystemStatsTable node
ipSystemStatsOutFragOKs not implemented: skipping

Feb  4 03:15:28 fc-netops snmpd[24166]: ipSystemStatsTable node
ipSystemStatsOutFragOKs not implemented: skipping

 

The only way to get SNMPD to start responding again is to restart it,
and it will again die.  I have never had these problems with any of my
other CentOS4/5/5.1 x86 or x86_64 boxes.  Both of these boxes (PowerEdge
1750's) are also running OMSA 5.2.0.

 

Has anyone seen this problem?

 

Thanks,

 

Josh
