    Custom UDP port in IP Monitor 10


      I wish to monitor a custom UDP port, but I can't find out how to do this on IPmontor.

      Please tell me that "IP"monitor can monitor custom UDP ports!?

      If so, how?

          This is not possible with any Network Monitoring Software.  As UDP is a sessionless protocol where blind requests are sent and hope is used to get a response, the only way to test if something is responding on a specific UDP port is to know how to communicate with it.

          For example, in order to test if SNMP is available on a system, ipMontior does not "connect" to UDP port 161.  It sends an SNMP GET request and waits for a response.  If it receives a response, it knows the port is available.  If it receives no response, it assumes that a port is closed or SNMP is not listening on that system.

          Having all that said, in order to test a UDP port, you would need to write a script that sends a command to that port and expect a response.  Once that script is written, simply use the External Process Monitor to run it.  Some example scripts that can be used with ipMonitor are found here:


          Hope this all makes sense.
