This is example of output from the different tables in the ZFS SNMP module.
It is from my test/development machine, which have a basically empty pool
used only for testing so the values isn't very exiting...
* Number of pools, datasets, volumes and snapshots
# snmpget -uro -v2c -cpublic localhost zfsTotalPools
BAYOUR-COM-MIB::zfsTotalPools.0 = INTEGER: 2
# snmpget -uro -v2c -cpublic localhost zfsTotalDatasets
BAYOUR-COM-MIB::zfsTotalDatasets.0 = INTEGER: 2
# snmpget -uro -v2c -cpublic localhost zfsTotalVolumes
BAYOUR-COM-MIB::zfsTotalVolumes.0 = INTEGER: 0
# snmpget -uro -v2c -cpublic localhost zfsTotalSnapshots
BAYOUR-COM-MIB::zfsTotalSnapshots.0 = INTEGER: 0
* The basic pool status table
# snmptable -uro -v2c -cpublic localhost zfsPoolStatusTable
SNMP table: BAYOUR-COM-MIB::zfsPoolStatusTable
zfsPoolName zfsPoolSize zfsPoolAlloc zfsPoolFree zfsPoolCap zfsPoolDedup zfsPoolHealth zfsPoolAltRoot zfsPoolUsedBySnaps zfsPoolUsed

to the same lines (pools)
