Hmm, even making 'zfsVFSIOPSEntry' augment 'zfsPoolStatusEntry' still
won't allow me to use 'zfsPoolName' in the sequence:

      zfsVFSIOPSTable                  OBJECT-TYPE
        SYNTAX                         SEQUENCE OF ZFSVFSIOPSEntry
        MAX-ACCESS                     not-accessible
        STATUS                         current
        DESCRIPTION                    "A list of ZFS VFS IOPS status information.
                                        This table contains additional objects for
                                        the zfsPoolStatusTable."
        ::= { zfsStats 8 }

        zfsVFSIOPSEntry                OBJECT-TYPE
          SYNTAX                       ZFSVFSIOPSEntry
          MAX-ACCESS                   not-accessible
          STATUS                       current
          DESCRIPTION                  "An entry containing ZFS ARC status values."
          AUGMENTS                     { zfsPoolStatusEntry }
          ::= { zfsVFSIOPSTable 1 }

          ZFSVFSIOPSEntry             ::= SEQUENCE {
            zfsVFSIOPSIndex           CounterIndex,

            zfsPoolName               DisplayString,
            zfsOperReads              Counter32,
            zfsOperWrites             Counter32
          }


BAYOUR-COM-MIB.txt:2215: SEQUENCE element #2 `zfsPoolName' is not a child node under `zfsVFSIOPSEntry'
BAYOUR-COM-MIB.txt:2215: warning: SEQUENCE element #3 `zfsOperReads' does not match order of columnar objects under `zfsVFSIOPSEntry'


Did I misunderstand something?


Removing the 'zfsPoolName' line, just gives me a broken table:

	$ snmptable localhost zfsVFSIOPSTable
	SNMP table: BAYOUR-COM-MIB::zfsVFSIOPSTable

	 zfsOperReads zfsOperWrites
	            0             0
	            0             0
	            0             0
	            0             0
	            4             ?
	      "test1"             ?
	      "test2"             ?
	      "test3"             ?

I want the pool name 'testX' as the first column, zfsOper* as two and three...


Should I just NOT output the pool name in the script? Will 'everyone' understand
that the first line is related to the first line of the output of the
'zfsPoolStatusTable'?
