Hi,

If you use numeric OIDs then you don't need to load the MIBs.  But, if you
would like to specify the OID symbolically, you need the MIB.  For
example, if you want to find the amount of DRAM in your system you can
specify the OID: .1.3.6.1.2.1.25.2.3.1.6.101. Doing it this way, there is
not need to load the HOST_RESOURCES-MIB.

If you load the MIB, you could specify the variable symbolically:
  hrStorageUsed.101.
