Make Dell's OpenManage 6.2 information available through SNMP

Question

I have successfully installed OpenManage on a CentOS 5.4 server and I'm able to use OpenManage through the web interface running on port 1311, but I would like to be able to expose this information through the SNMP server. I don't know SNMP particularly well so the configuration is a result of trial and error.

I've tried to follow the description pointed out in the Open Manage Server Administrator User Guide. I've followed the documentation regarding SNMP configuration, but without success.

I've created a small snmpd.conf file:

com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1
access notConfigGroup "" any noauth exact all all none
view all included .1
rwcommunity public 10.200.26.50
syslocation "Somewhere"
syscontact [email protected]
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
smuxpeer .1.3.6.1.4.1.674.10892.1

When I try to fetch SNMP information by using snmpwalk I get the following output:

SNMPv2-MIB::sysDescr.0 = STRING: Linux myserver.test.com 2.6.18-164.15.1.el5 #1

I suspect that I should get some DELL specific information when I use the snmpwalk utility. Is there a configuration in snmpd.conf file which is wrong, or do I have to configure on the OpenManage side in order to get the hardware information accessible from SNMP?

Update: Could mib files help me interpret the information returned from snmpwalk? I see that several mib files is located under /opt/dell/srvadmin/.

Update 2: I've verified that the SNMP daemon doesn't return any of Dell OIDs which means that either the snmpd.conf file is wrong or else there's some OpenManage configuration which is missing.

Solution

Here's a setup which now works

1. Install the repository

   wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash

2. Install the required software

   yum install net-snmp OpenIPMI srvadmin-all

3. Configure SNMP:

Here how our current snmpd.conf file look like

\# DELL Stuff
\# sec.name source community
com2sec notConfigUser default public

\# groupName securityModel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser

\# Make at least snmpwalk -v 1 localhost -c public system fast again.
\# name incl/excl subtree mask(optional)
view all included .1
view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1.25.1.1

\# group context sec.model sec.level prefix read write notif
access notConfigGroup "" any noauth exact all none none

\# Added for support of bcm5820 cards.
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat

\# Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX
smuxpeer .1.3.6.1.4.1.674.10892.1

Could you explain what happens when all that is present in the snmp.conbf file is that single line. Does the text ":StorageManagement-MIB" restrict part of the "SNMP-tree" which is exposed? I see that the following mib files got copied into the /usr/share/snmp/mibs directory: 10892.mib, dcs3fru.mib, dcs3rmt.mib, dcstorag.mib
