New Solaris features: Notif...

The notification framework in Solaris is not only able to notify you of problems with services. As you may know, the fault management architecture monitors the hardware of a Solaris system. With the fmdump command you can retrieve the information. For example you get this informatoin when you unplug an USB stick with an active ZFS filesystem:

root@solaris:/home/jmoekamp# fmdump -v
TIME UUID SUNW-MSG-ID EVENT

Nov 22 12:59:48.7489 22dffa96-bf27-4f41-ab1f-dfedcdfb11e7 ZFS-8000-HC Diagnosed
100% fault.fs.zfs.io_failure_wait

Problem in: zfs://pool=usbstick1
Affects: zfs://pool=usbstick1
FRU: -
Location: -

Wouldn't it be nice to receive this and similar information about the failure of components. It's really simple to configure. However i assume , that you've already installed smtp-notify package with

root@solaris:/# pkg install service/fault-management/smtp-notify

To configure the notification, you just have to configure the target mail adress for the mails.

root@solaris:/# svccfg setnotify problem-diagnosed mailto:root@localhost

To check the configuration you can use the listnotify command:

root@solaris:/# svccfg listnotify problem-diagnosed
    Event: problem-diagnosed (source: svc:/system/fm/notify-params:default)
        Notification Type: smtp
            Active: true
            reply-to: root@localhost
            to: root@localhost

        Notification Type: snmp
            Active: true

        Notification Type: syslog
            Active: true

When you unplug the USB-stick with while the ZFS pool is imported, you will find a mail like this one in your mailbox:

root@solaris:/# mail
