What is monitor service port?
Service port monitoring involves monitoring services running on different ports. This can include services running on ports such as Telnet, TCP/IP port, etc.
How do you know which service is running on which port?
Check listening ports with netstat
- Check ports. To list the TCP ports that are being listened on, and the name of each listener’s daemon and its PID, run the following command: sudo netstat -plnt.
- Filter the list. If the list of listening daemons is long, you can use grep to filter it.
- Analyze the results.
How does portmon work to monitor a port?

How to use netstat command in Windows to watch open ports?
Let me explain how to Netstat command in Windows. First, just open a command prompt window and type: netstat -an. The -a parameter lists all the computer’s connections and listening ports, while the -n parameter displays addresses and port numbers in numerical format. A typical (truncated) result from Netstat -an looks like this:
