<p><strong>Host - first notification delay<br></strong></p>
<p>This directive is used to define the number of "time units" to wait before sending out the first problem notification when this host enters a non-UP state. Unless you've changed the interval_length directive from the default value of 60, this number will mean minutes. If you set this value to 0, Nagios will start sending out notifications immediately.</p>
