Thanks for an excellent job, makes it much easier to monitor zfs using nagios. One question How to print detailed output? We always get result like

OK: ZFS on testsystem - No zfs failures detected

Can we print zpool names, free space etc?

Thanks
Good check, but the script has problems checking zpools with solaris 11, as a new column has been added: DEDUP.

I've made a change into get_zpool_data() and it worked.

next if (/^NAME\s+SIZE\s+USED\s+AVAIL\s+CAP\s+DEDUP\s+HEALTH\s+ALTROOT/);
my ( $pool, $size, $used, $avail, $cap, $dedup, $health, $altroot ) = split( /\s+/, $_ );

#@{$pools{$pool}} = ($pool, $size, $used, $avail, $cap, $health, $altroot);
$zpools{$pool} = {
size => "$size",
used => "$used",
avail => "$avail",
cap => "$cap",
dedup => "$dedup",
health => "$health",
altroot => "$altroot",
};

I expect it could be useful for others.

Yes, We are getting only this output.

"OK: ZFS on testsystem - No zfs failures detected"

can we get more detailed output for ZPOOL and DATASET. No need of hostname in output.

Ex:

OK ZPOOL rpool : ONLINE {Size:149G Used:5.73G Avail:143G Cap:3% Dedup:1.00x}
Hello

thanks for the check, it works locally on my Solaris10 box also for the nagios user without sudo configurations, so I updated my nrpe.cfg with a line like:
command[check_zfs_pools]=/opt/csw/libexec/nagios-plugins/check_zfs.pl -p

but Nagios side when it doesn't work:
[root@t3nagios ~]# /opt/nagios-plugins/lib/nagios/plugins/check_nrpe -H t3fs11 -c check_zfs_pools
NRPE: Unable to read output

please some clues ?

many thanks,
fabio
