Monit needs to read the Process ID of SimpleHelp (assuming it is a 
server-program) from a file. A so called pid-file which contains one entry only 
which is the process-id. This file must then be specified in the check process 
statement which could look something like

  check process SimpleHelp with path /opt/SimpleHelp/simplehelp.pid
   start program = "/etc/init.d/simplehelp start"
  stop program = "/etc/init.d/simplehelp stop”

If your script needs to create the pid file, do something like this in bash: 
echo $$ > /opt/SimpleHelp/simplehelp.pid;
$$ is the process-id of the script. Don’t background anything with ‘&’ in which 
case the process-id will be wrong. More info can be found here:
