Custom SNMP monitoring

How to setup Dell OMSA SNMP monitoring

Install snmp from Net-SNMP repository, they have an rpm done, it was made thinking in Fedora, but since this is an rpm builded from pure code it will run fine on any rpm distro, like CentOS.

# wget wget http://superb-east.dl.sourceforge.net/sourceforge/net-snmp/net-snmp-5.4.1-1.fc6.i386.rpm
# rpm -Uvh net-snmp-5.4.1-1.fc6.i386.rpm

When rpm is executed in a system that already have installed OMSA, it will return

error: Failed dependencies:
       net-snmp = 5.0.1-6 conflicts with srvadmin-deng-5.3.0-438.i386

But the request command returns

# rpm -q --provides net-snmp
net-snmp
net-snmp-utils
libnetsnmp.so.15
libnetsnmpagent.so.15
libnetsnmphelpers.so.15
libnetsnmpmibs.so.15
libnetsnmptrapd.so.15
net-snmp = 5.4.1-1

Then is safe to run

# rpm -Uvh --nodeps net-snmp-5.4.1-1.fc6.i386.rpm

SNMP configuration for OMSA

• Enable SNMP support

# service dataeng enablesnmp

• Copy Dell mibs to snmp mibs directory

# cp /opt/dell/srvadmin/omsa/*.mib  /usr/share/snmp/mibs

• Add Dell mibs to /etc/snmp/snmp.conf

# mibs +MIB-Dell-10892:StorageManagement-MIB

• Restart SNMP Service

service snmpd restart
