How do I get the system UUID information from the MIB ?

Which MIB value points to the UUID info of the machine.

I have seen that its possible to get this details as some software does that.

Need some help on this ?

I am unable to find the MIB related to the UUID. But after searching I was able to get a OID 1.3.6.1.1.16.1
This OID is related for RFC 4122. But I am unable to get the value from this OID.

Command :# snmpget -v 1 -c public <System IP Address> iso.3.6.1.1.16.1
Got an error :- Failed object: SNMPv2-SMI::directory.16.1

I don't know how to get this value?

Need your help on this.

I'm not sure exactly what UUID you are referring to, but you made me curious about getting the UUID from the BIOS of a Linux box via SNMP. I was able to do it, but only by using the "exec" feature, which I defined in my snmpd.conf file. So in my /etc/snmp/snmpd.conf file, I have:

rocommunity public
exec .1.3.6.1.4.1.2021.50 shelltest /bin/sh /tmp/uuid.sh

and in /tmp/uuid.sh I have:

#!/bin/sh
dmidecode|grep UUID

Then on a remote box, I ran:

snmpwalk -v1 -c public <IPADDR_OF_FIRST_PC> .1.3.6.1.4.1.2021.50

And it returned, amongst some other stuff:

UCD-SNMP-MIB::ucdavis.50.100.1 = STRING: "    UUID: 000000000-0001-0002-0003-000400080009"

Probably not what you want, though....

Thanks for your reply atreyu.
This solution will work for a linux system where I can make these changes which you ave mentioned.

I am trying to find a solution which will work for any system.
Like a storage box, a linux system, etc.
Every system does have a UUID which I want to capture. But your solution will be applied on the linux system but not on a storage or other systems.

Please help me in finding this solution which will be a generic solution for all the system in the datacenter.

That may be a tall order. It depends entirely on your SNMP agents, and what they choose to make available via SNMP queries. Have you already walked the entire tree of one of your devices and looked for the UUID and not found it? If so, then I'm afraid I can't be much more help.

When you do the snmpwalk command, try playing with the "-O" flag to modify the output.

E.g., this will print full OIDs on output:

snmpwalk -c public -v2c <DEVICE_IPADDR> -Of|grep -i uuid

Or if you already know a UUID for a given device some other way:

snmpwalk -c public -v2c <DEVICE_IPADDR> -Of|grep -i <KNOWN_UUID>
