obdiag-multi-cluster

Switch between multiple OceanBase clusters in a single obdiag session by discovering available cluster profiles under ~/.obdiag/ and using the /use command to direct subsequent diagnostic operations to a specific target cluster.

Check the currently active OceanBase cluster for obdiag by using the show_current_cluster command, which displays the active config_path and its resolved cluster configuration details for your ongoing session.

List all available OceanBase cluster configurations for obdiag by running the list_obdiag_clusters command, which scans the ~/.obdiag/ directory and displays cluster configuration files alongside their short names.

Yes, you can direct obdiag operations to a specific cluster by setting the cluster_config_path variable with the full path to the target cluster profile, ensuring all following diagnostic tools execute with cluster awareness.

You do not need to specify the full cluster_config_path every time; once you switch to a target cluster using its short name, the active session configuration automatically applies to all subsequent obdiag operations.

Limitations of obdiag multi-cluster session management include relying on predefined cluster configuration files located in the ~/.obdiag/ directory, meaning any cluster not registered there cannot be discovered or targeted for switching.
