Configuring TCP Ports for Discovery

Discovery of components in a specific IP range is typically based on the port number(s) on which the components are listening. Each component type supported by eG Enterprise is mapped to a set of port numbers. You can, if need be, change the default port preferences mapped to each component type. For instance, the default port mapped to an Apache Tomcat server is 8080. If your environment comprises of a few Tomcat servers that listen on port 8080 and a few others that listen on port 8088, the discovery process will by default discover only those Tomcat servers that run on port 8080. To ensure that the discovery process automatically discovers the Tomcat servers that listen on 8080 and the ones that listen on 8088, do the following:

  1. Login to the eG admin interface.

  2. Follow the Infrastructure -> Discovery menu sequence.

  3. Click the TCP Ports option under the Settings sub-node of the Discovery node in the DISCOVERY tree in the left panel.

  4. The COMMON SETTINGS - TCP PORTS FOR APPLICATION DISCOVERY page will then appear in the right panel.

  5. The TCP ports for application discovery section in the page will reveal the default ports for all component types that eG Enterprise monitors out-of-the-box.

  6. If you want to view the ports configured for all those component types that have been explicitly chosen for auto-discovery, then select the Show component types for discovery check box. The component types and port configurations displayed in the TCP ports for application discovery section will display the chosen component types and corresponding ports.

  7. For instance, if you wish to edit the port(s) at which the Tomcat server listens, scroll down the TCP ports for application discovery section until you can see the Tomcat entry. Then, click on the ports displayed against Tomcat. The ports will become editable. To make sure that the Tomcat servers listening on 443 are also discovered, append that port number of the existing list of Tomcat ports, using the comma as a separator.

  8. Finally, click the Update button to save the changes.
