By default all columns of the SNMP table will be collected - it is not required
to add a nested field for each column, only those which you wish to modify. To
*only* collect certain columns, omit the `oid` from the `table` section and only
include `oid` settings in `field` sections. For more complex include/exclude
cases for columns use [metric filtering][].
One [metric][] is created for each row of the SNMP table.
