Here is a quick NETSTAT script that runs every 60 seconds and appends the output to c:\ports\netstat.txt. The script exports the count of connections in a specific state. The output is very similar to what TcpView shows you at the bottom of the GUI with connections in TIME_WAIT, ESTABLISHED, LISTENING, CLOSE_WAIT. You can copy this to a port_count.bat and run it as a scheduled task.
@ECHO OFF
:100
ECHO %date% %time% >> c:\ports\netstat.txt
ECHO Count of all open ports: >> c:\ports\netstat.txt
netstat -an | find /c “:” >> c:\ports\netstat.txt
ECHO Count of all ports in TIME_WAIT state: >> c:\ports\netstat.txt
netstat -an | find /c “TIME_WAIT” >> c:\ports\netstat.txt
ECHO Count of all ports in ESTABLISHED state: >> c:\ports\netstat.txt
netstat -an | find /c “ESTABLISHED” >> c:\ports\netstat.txt
ECHO Count of all connections to port 8085: >> c:\ports\netstat.txt
netstat -an | find /c “:8085” >> c:\ports\netstat.txt
ECHO Count of all ports in LISTENING state: >> c:\ports\netstat.txt
netstat -an | find /c “LISTENING” >> c:\ports\netstat.txt
ECHO Count of all ports in CLOSE_WAIT state: >> c:\ports\netstat.txt
