Title   How to find the Sentry-go listen port number
Applies To   Sentry-go Monitor

Question:
 
How can I determine which port my Sentry-go monitor is listening for requests on ?
 

Answer:
 
The Sentry-go integrated web server & Console request handler both use a TCP/IP port to listen for inbound requests from clients. Clients (e.g. the web browser, Client Console) must know this number in order to communicate with the monitor.

To find the TCP/IP Listen Port for a monitor registered with the Client Console ...
  • Start the Client Console.
  • Configure the appropriate server from the list (right click over the server name and click "Configure Monitor" or "Configure Local Monitor".
  • From the resulting window, select the "Settings" tab.
  • The defined port number is shown against the "The web server listens for requests on port" entry.

    The port number is fixed on remote machines & cannot be changed. To update the number to a new value you must configure the monitor locally (on the server itself). Bear in mind that changing the port number will invalidate any Client Consoles accessing the server on the old port. The port must be edited on each client in order to restore connectivity from them.
To find the TCP/IP Listen Port for a monitor that ias not already registered with the Client Console ...
  • Logon to the server running the Sentry-go service.
  • Locate the monitor's configuration location.
     
    This is a writeable location configured originally by the Setup Wizard. Depending on the version of Windows, it will be something like C:\ProgramData\Sentry-go
     
  • Within this directory locate the Sentry-go.cfg file & open it in Notepad.
     
    This is the configuration file for the monitor & is normally conifgured through the Console. Do not edit this file directly unless you are sure you know the change to make.
  • Locate the "[General]" section.
  • Within this section, locate the HTTPListenPort=X line, where X is a number.
  • The number indicated here is the listen port being used by the monitor.

Additional Information:
  

  • The default listen port for versions prior to v2.0 is 80 or above. or above.

  • The default listen port for versions prior to v2.0 is 1000 or above.
