Where are SNMP OID's defined

Is there a way to look up an OID and see what value it is supposed to return?  I don't see how a MIB file maps a friendly name to an OID without any reference to the OID in the MIB file.  I am properly misunderstanding how this all works.

Example:
JVM-MANAGEMENT-MIB::jvmMemoryHeapUsed <maps-to> 1.3.6.1.4.1.42.2.145.3.163.1.1.2, but how would one know this??

If someone could please explain, that would be great!

Excellent, thank you very much.

Where does this come from?
3.163.1.1.2

Also, how would I access the value jvmOSName? Would it be like this... MANAGEMENT-MIB::jvmOSGroup::jvmOSName ??

jvmOSGroup OBJECT-GROUP
    OBJECTS {
             jvmOSName,
           jvmOSArch,
           jvmOSVersion,
           jvmOSProcessorCount

VALUE standard [UNIVERSAL 6] OBJECT IDENTIFIER
    ::= 1.3.6.1.4.1.42.2.145.3 from MIB Browser http://www.mibble.org/

you can peruse the source if you want more.. also if you open the mib in a text editor you can find what you can use and the values returned.

Hi,

I understand where 1.3.6.1.4.1.42.2.145 come from as you explained that very clearly. Am I misunderstanding an important concept here? I am assuming that the MIB: JVM would define the 3.163.1.1.2 section which must point to a specific piece of information.

How would I know what the OID 3.163.1.1.2 is referencing?

After looking at this site: IPMonitor I can see what I was expecting, a mapping between OID and the name.

So I see where I can see the mapping, but it's only possible using a MIB browser?

Thanks!
