I see your script is checking if the process is running, using logger to log the status and terminating. This is the reason why you are not seeing it running. You should put this in an infinite while loop with a sleep time of your choice for periodically checking and logging the status.

E.g:-

Code:
#!/bin/bash
PROCESS="httpd" 

while (true)
do
if /etc/init.d/$PROCESS status | grep running.> /dev/null 
then 
      logger -s "$PROCESS is running" 
else 
      logger -s "$PROCESS is not running" 
fi
sleep 300
done

Now you can start your script using nohup and open another terminal to check if it is running:-

Code:
nohup /usr/local/bin/process &

Code:
ps -eaf | grep /usr/local/bin/process | grep -v grep

I hope this helps.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
