Note: Before installing a gateway, ensure you have installed and configured a Distributed Edition of the server. All other Network Monitor installations sending data to the server should be installed using the Gateway option.
Configuring a Gateway
Create a new entry for the gateway by clicking the Create gateway link from the Distributed settings menu of the KNM server.
Gateway properties page
Name - Name of the gateway.
Description - A longer description of the gateway.
Address/Port - The primary IP address and port the gateway sends data to. If the server is installed behind a NAT firewall, specify the external IP and port of the NAT firewall. The NAT firewall should then be configured to redirect to the internal IP and port specified by the Server IP and Port fields of the Server configuration page. If, for evaluation purposes, a Network Monitor server and gateway are installed on the same subnet, the Address and Port fields on this page should match the Server IP and Port fields on the Server configuration page.
Address/Port - Optional server backup addresses. The gateway tries these addresses if it can't connect to the server using the primary address.
Max buffer time - When the gateway cannot connect to the server, the gateway buffers data for the specified time before suspending its operation.
To save the settings click the Save button.
Gateway configuration files
The deployed configuration file is created when a Gateway configuration is saved on the KNM server.
While installing Network Monitor on the gateway host machine, ensure the Gateway option is selected.
Install the deployed configuration file created by the KNM server on its corresponding gateway.
To retrieve this file, first click the gateway on the Distributed settings page of the KNM server. the Gateway information page displays. Select the Download configuration command.
Save the zip file that is returned to your browser. If you experience problems downloading the zip file you can find the required files in the KNM\gateways folder of the KNM host machine.
Stop the gateway's nmservice.exe service, if it is running.
Extract the zip file into the root KNM directory of the gateway.
Restart the gateway's nmservice.exe service using the service control manager.
The gateway is now ready for use.
Note: If you change the gateway configuration, the configuration file must be updated and the gateway's nmservice.exe service restarted.
