  these arguments supplied automatically for all external monitors: 
  $1 = IP (nnn.nnn.nnn.nnn notation) 
  $2 = port (decimal, host byte order) 
  
  additional command line arguments ($3 and higher) may be specified in the monitor template 
  This example does not expect any additional command line arguments 
  
  Name/Value pairs may also be specified in the monitor template 
  This example expects the following Name/Vaule pairs: 
   URI  = the URI to request from the server 
   RECV = the expected response (not case sensitive) 
  
  
 PIDFILE="/var/run/`basename ${0}`.${NODE}_${PORT}.pid" 
  kill of the last instance of this monitor if hung and log current pid 
 if [ -f $PIDFILE ] 
 then 
    kill -9 `cat $PIDFILE` > /dev/null 2>&1

  remove IPv6/IPv4 compatibility prefix (LTM passes addresses in IPv6 format) 
 NODE=`echo ${1} | sed 's/::ffff://'` 
 PORT=${2} 
  
  set the value for the Host header based on IP 
  (defaults to IP address if IP doesn't match)

  send request & check for expected response 
 curl --ntlm -v -u 'DOMAIN\username:pswd' http://${NODE}:${PORT}${URI} -H "Host: ${HOST}" | grep -i "${RECV}" 2>&1 > /dev/null 
  
  mark node UP if expected response was received 
 if [ $? -eq 0 ] 
 then 
     echo "UP"
