H.8 Restart
When you start Nagios, it rechecks the configuration each time for errors and dependencies. Depending on the specific environment, this can be very quick, or it may last a long time, during which Nagios will not operate. In Nagios 3.0 there is an option to disconnect this test from the restart and instead save the result in a separate temporary file. When Nagios starts, it will read this file, and the otherwise usual processing of objects is left out at this point. Whether this is worthwhile or not is revealed by nagios -s:
