We are trying to monitoring the Dell PowerEdge server via iDrac 5. The OS currently running is Red Hat Linux. From my research and study. if I want to monitoring the server H/W health using SNMP through iDrac. The server has to install the OMSA software and the OMSA services have to be started. I believe the document mention that iDrac 7 has full snmp package, therefore the OMSA won't need to be installed.
Here is my questions, I hope anyone could help me to clear out the question.
1. Do I need to install the OMSA on the RedHat in order to monitoring H/W if i am using the SNMP protocol through iDrac port ? Someone told me it won't need to be installed which I don't think it is correct.
2.Do I must enable SNMP pass through on OMSA configuration in order to get the data through iDrac port?
3. Do you have to use different OID if you query SNMP through Ethernet port or iDrac ?
4. One of my server has only two services running
dsm_sa_datamgr32d is running
dsm_sa_eventmgr32d is running
and without dsm_sa_snmp32d (not sure why it is not showing up when starting dataeng serveice), will that be the reason that I can't get any snmp data response ?
