Restart smartd on Check Interval change

Configure smart service

Set critical to 20

Set a timer for 2 minutes

Refresh UI nothing happens

Get the process ID using ps -auwx | grep smartd

Kill the smartd process by issuing kill -9 and the PID

Relaunch smartd with /usr/local/sbin/smartd -n -i 1800 -c /usr/local/etc/smartd.conf -p /var/run/smartd-daemon.pid &

Imeddiatiley temperature alerts will appear in console messages or by cat /var/log/messages

Wait 2 minutes

Refresh UI if necessary and alerts will appear

After talking with William Grzybowski this seems like a bug because the service should not require a restart to apply this setting.  If this is incorrect we just need to know to rewrite our SMART test case for alerts services, and it may make sense to warn in the UI somehow.
