I'm running monit with Nginx with no problems. It shows up properly in
the access logs.

check process nginx with pidfile /var/run/nginx.pid
  group webserver # webserver group
  start program = "/etc/init.d/nginx start"
  stop program  = "/etc/init.d/nginx stop"
  ## Test port 80 and request the server status page. Restart if the
  ## server is down.
  if failed port 80 protocol http then restart
  ## If the restarts attempts fail then alert.   
  if 3 restarts within 5 cycles then timeout
  depends on nginxd
  depends on nginx_init
  alert address@hidden only on {timeout}    

## Test the nginx binary.
check file nginxd with path /usr/sbin/nginx
   group webserver
   if failed checksum then unmonitor
   if failed permission 755 then unmonitor
   if failed uid root then unmonitor
   if failed gid root then unmonitor
   alert address@hidden  

## Test the init scripts.
check file nginx_init with path /etc/init.d/nginx
   group webserver
   if failed checksum then unmonitor
   if failed permission 755 then unmonitor
   if failed uid root then unmonitor
   if failed gid root then unmonitor
   alert address@hidden

This assumes that 127.0.0.1:80 has Nginx listening in. What does it
shows in the logs?
