Troubleshooting data monitoring

[Version 8.6 and later]Use this information to troubleshoot monitoring activities that you complete with the WebSphere® eXtreme Scale web console or other utilities to monitor the performance of your application environment.

Procedure

Problem: You cannot switch between domains with different security settings in the WebSphere eXtreme Scale web console.

You can switch domains between two unsecure domains. You can also switch domains between two secure domains with the same security configured. However, you cannot switch between one unsecure and one secure domain or between two secure domains with different security settings.

Diagnosis: The startOgServer command is used to start two different catalog servers in separate domains. Each catalog server is unaware of the other. However, both catalog servers are started with the same domain name. When you do not specify the domain name, both catalog servers start in different domains with the default name, DefaultDomain. In addition, the monitoring console displays data for only one of the catalog server domains.

Cause: When you switch domains in the monitoring console, you are connected to the second domain. However, no grid data from that domain is displayed, and the first domain grid data is still in view. Therefore, during run time, both catalog servers run in separate domains with the name, DefaultDomain.

Solution: Determine which domain names are used when catalog servers start in the two domains. To identify the domain names, analyze your startOgServer command syntax and investigate what domain is being specified.

Since this problem scenario is not supported, complete the following actions to display the correct catalog service domain statistics:

  1. Shut down your catalog servers, and verify that they are configured to start with unique domain names.
  2. Restart your monitor console.
  3. Optional: If an outage is not possible, consider running a second monitoring console to monitor the second domain.
