1. On your Data Synchronizer Server install & configure the product "net-snmp".

• Open the firewall for 161 UDP (just for your monitoring machine)

• Allow access by adding a line like
  

  
  rocommunity public IPAddressOfMonitoringMachine
  

  
  to "/etc/snmp/snmpd.conf"

• Create a script "/root/bin/con.sh" like this:
  

  
  #!/bin/sh
  LINES=$(/bin/netstat -an | /bin/grep  -c ':443'  )
  echo $LINES
  exit $LINES
  

  
   

• Make it executable
  

  chmod  x /root/bin/con.sh

  
  

• Add an "exec" statement to the "/etc/snmp/snmpd.conf" using a free/unused OID (you can use the one in this example).
  

  
  exec 1.3.6.1.4.1.2021.8.1.100 /root/bin/con.sh
  

  
   

• Restart the snmpd
  

  rcsnmpd restart

  
  

snmpwalk -Os -c public -v 1 localhost 1.3.6.1.4.1.2021.8.1.100
