A common request from smaller shops or private users of Solaris is that they want email notifications when something is wrong with their system. This is most common with ZFS filers, they might not have any surveillance systems implemented but want to be sure to get a notification if something goes wrong with a zpool. A quick fix to this is of course a small script which can dump zpool or FMA errors over email but it is not a standardized or complete solution.
Now there have been a large putback in OpenSolaris that among other things delivers this functionality. FMA faults and SMF events can with these change be configured to deliver notifications over mail or SNMP. It also enables the fault management daemon in local zones so that they can deliver SMF state changes from within the zone. Using this framework you can also configure any of your own SMF services to deliver state change notification over any of these two protocols.
