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:
<Threshold>
<Plugin "load">
WarningMin 0 # dummy threshold
</Plugin>
</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.

Andrés
