The current default index pattern in Elastic Search is set to 'kubernetes_namespace_name', which needs to be updated to 'kubernetes.namespace_name'. This change is required to align with the standard naming conventions and improve query performance.

Acceptance Criteria
The default index pattern in Elastic Search is verified to be 'kubernetes.namespace_name'.
All existing data indexed under 'kubernetes_namespace_name' is accessible with the new index pattern.
Elastic Search queries and dashboards are updated to reflect the new index pattern without any loss in functionality.
A reindexing strategy is outlined and executed if necessary to migrate data from the old index pattern to the new one without data loss.
Comprehensive testing is performed to ensure that the update does not impact the performance and functionality of Elastic Search.
