In agent configuration on the node add this:
[ExternalTable/ZpoolStatus]
Command = zpool status | tr -s ' ' | sed '1,5d' | sed 's/^[ \t]*//;s/[ \t]*$//' | sed 's/ /|/g' | sed 'N;$!P;$!D;$d'
Separator = |
InstanceColumns = Index
Description = ZpoolStatus
PollingInterval = 320
Do a restart agent and then a config poll.
After that you should be able to go to Data Collection Configuration on that node and add a new Table.
thanks
