Custom TCP Monitor

Hi again,

I am actually running into this issue myself now where I'd like to be able to use a null character in the send and/or receive string for a TCP monitor. Do you mind sharing your case number so I can pass it along to F5 Support as a reference for my case? Mine is C569837.

You might want to add the PID checking to ensure only one instance of the monitor per pool member is running at a time. It's more of a best practice than a functional requirement though.

 
   Formulate the PID filename based on the script name, pool member IP and port 
  PIDFILE="/var/run/`basename ${0}`.${NODE}_${PORT}.pid" 
  
   If the PID file already exists, it means the last instance of this monitor  
   is probably hung. 
  if [ -f $PIDFILE ]  
  then  
      Stop the current process 
     kill -9 `cat $PIDFILE` > /dev/null 2>&1  
  fi  
  
   Create a new PID file 
  echo "$$" > $PIDFILE  
 

And then at the end of the script:

 
  Remove the PID file 
 rm -f $PIDFILE 
 

Thanks,

Aaron
