Unable to see any applications in 'Top Applications' on a FortiGate

We'll go through the quick steps to re-enable Application logging so that this dashboard shows us the correct applications.

How-to: Send email alerts from a FortiGate

With FortiOS version 5, the Alert E-Mail option has been removed from the GUI by default unless a messaging server has been configured.
