That's because the check-httpd script expects a number of command line
arguments that are passed to it and specific values before taking
action. If it doesn't see those, it just exits cleanly. You can read the
script to see what those are.

define command{
	command_name	restart-httpd
	command_line
/usr/local/nagios/libexec/eventhandlers/restart-httpd  $SERVICESTATE$
$SERVICESTATETYPE$ $SERVICEATTEMPT$
	}

Nagios will substitute appropriate information for the $MACROS$ when
calling your script. The end result would be something like --

/usr/local/nagios/libexec/eventhandlers/restart-httpd CRITICAL SOFT 1
Or
/usr/local/nagios/libexec/eventhandlers/restart-httpd CRITICAL HARD 3

Not if you're wanting to see if your event handler, when run with root
permissions, will restart httpd. If you want to test if nagios can run
it then you need to become the nagios user (after setting up sudo and
your event handler as previously noted) then call the event handler
directly.
