Hub connectivity administration

Hub connectivity administration is used to validate that a requested hub Tivoli Enterprise Monitoring Server can be reached through a TCP/IP connection during the operation of the OMEGAMON enhanced 3270 user interface.

Hub connectivity administration provides information about the user interface address space that you are running in, on what LPAR, and, in what Sysplex. If your current profile does not specify a hub monitoring server for your user interface address space, hub connectivity administration assists you in locating all the available hub monitoring servers in your Sysplex. When you locate the available hub monitoring servers, hub connectivity administration then helps you to select and make a good connection to the hub. When you establish a good hub connection, the connection produces useful data on the user interface.

Hub connectivity administration also provides you with the following information:

  • A status overview of every hub monitoring server that is known to the user interface
  • The Managed System Names and Managed System Lists that are known for each hub monitoring server
  • The starting point for access to the IBM Tivoli Monitoring Service Index, Tivoli Monitoring Service Consoles, and Tivoli Monitoring SOAP servers that are known for each hub monitoring server.

Multi-hub support

You can use the multi-hub support feature to select a secondary hub monitoring server connection. When you select a secondary hub connection, you can switch between your primary and secondary hub connections. For example, if your site runs multiple hub monitoring configurations, you can use this feature to quickly switch between configurations. You can switch connections manually, or automatically, for example in the event of an unavailable hub connection.
Secondary Hub Connection
Multi-hub support does not provide a mechanism to make your secondary hub connection a backup or failover of your primary hub connection. Unless you have other mechanisms in place to provide a backup or failover hub monitoring server, it is more likely that your secondary hub connection is monitoring another configuration. For example, your primary hub might be monitoring the production systems configuration, while your secondary hub might be monitoring the test systems configuration.
