A simple cron script to monitor the health of a ZFS pool and email you if there are any problems. Tested on Ubuntu 12.04: (Taken from http://zfsguru.com/forum/zfsgurudevelopment/269)
#!/bin/bash
EMAIL_ADD=email@address.com
zpool status -x | grep 'all pools are healthy'
if [ $? -ne 0 ]; then
/bin/date > /tmp/zfs.stat
echo >> /tmp/zfs.stat
/bin/hostname >> /tmp/zfs.stat
echo >> /tmp/zfs.stat
/sbin/zpool status -x >> /tmp/zfs.stat
cat /tmp/zfs.stat | /bin/mail -s "Disk failure in server : `hostname`" $EMAIL_ADD
fi

I just wanted to comment that this bit of scripting was useful, thanks!!
I created this as root in /root/scripts/zfs_health.sh
I set it up in crontab to run hourly and redirected output to /dev/null
I had to fully path the /sbin/zpool command on ubuntu 12.04, and mail was in /usr/bin
Thanks!
I updated the paths for Ubuntu 16.04
$ cat zpoolstatuscheckemail.sh
#!/bin/bash
# Version 1.0
# 06/23/2016
EMAIL_ADD=[email goes here]
zpool status -x | grep 'all pools are healthy'
if [ $? -ne 0 ]; then
/bin/date > /tmp/zfs.stat
echo >> /tmp/zfs.stat
/bin/hostname >> /tmp/zfs.stat
echo >> /tmp/zfs.stat
/sbin/zpool status -x >> /tmp/zfs.stat
cat /tmp/zfs.stat | /usr/bin/mail -s "Disk failure in server : `hostname`" $EMAIL_ADD
fi
