You can define a threshold to do this, if you only need a "online"
threshold, that is
only send an alert when host down, you can use a dummy threshold like this:

  <Plugin "load">
     WarningMin 0 # dummy threshold

So, the threshold never raises, because load never will be lower than 0,
but when NaN, a FAILURE alert will be dispatched.

You can combine this with notify_email plugin to send emails.
