field names. like interface, cpu utilization, memory free, memory used, etc, instead of OID

If you want to trim iso.org.dod.internet.mgmt.mib-2.ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.10101 down to just ifName you could use something similar to [this](https://discuss.elastic.co/t/rename-snmp-dynamic-fields/208236/4). Obviously you would have to change the if and add a second gsub to strip the leading elements of the name.
