There are no OMEGAMON Enhanced 3270 user interface data retrieval agents registered

Verify that there are registered OMEGAMON Enhanced 3270 user interface data retrieval agents online.

The OMEGAMON Enhanced 3270 user interface startup process discovers WLM-registered data retrieval agents and connects to the data retrieval agents to retrieve hub monitoring server information about OMEGAMON agent data sources. This information is stored in the OMEGAMON Enhanced 3270 user interface local registry. By default, the registry information is refreshed every 5 minutes.

If you verified the existence of a custom profile, in which the hub monitoring server settings are correctly specified, but the no data condition persists, you need to verify that there are registered data retrieval agents.

From the OMEGAMON Enhanced 3270 user interface, you can open a workspace that displays DRA information. Use the following procedure to open the workspace.

Procedure

From the All Known Hubs (KOBHUBS) workspace, place your cursor next to the hub monitoring server name that you are interested in, type A and press Enter.

The Data Retrieval Agents (DRA) workspace is displayed.
Figure 1. Data Retrieval Agents (KOBHBDRA) workspace.
Data Retrieval Agents (DRA) workspace.

The three rows that are shown in the Data Retrieval Agents (DRA) workspace indicate that there are three registered data retrieval agents for the hub monitoring server as RTE1:CMS running in the same Sysplex as the OMEGAMON Enhanced 3270 user interface address space. Assuming that there are no problems with agent data collection, the OMEGAMON Enhanced 3270 user interface is able to connect to any one of these data retrieval agents to retrieve OMEGAMON data from a V5.1.0 or later monitoring agent that is connected to the RTE1:CMS hub monitoring server.

If data retrieval agents are not registered for a specific hub monitoring server, the KOBHBDRA workspace is empty.

If the All Known Hubs (KOBHUBS) workspace list does not contain the hub monitoring server that is specified in the OMEGAMON Enhanced 3270 user interface logon profile, a high probability exists that the OMEGAMON for z/OS agents and or related monitoring server address space are offline.
