Enabling and configuring cross-cluster search
Cross-cluster search (CCS) is an important feature provided by the Elastic Stack, enabling users to query multiple clusters simultaneously and obtain an aggregated view from multiple data sources. It can be employed in various scenarios such as data isolation/aggregation, resource efficiency management, combined data analysis, hybrid environments, and more. In this recipe, we will learn how to establish trust relationships and explore how CCS can be beneficial through concrete examples of data isolation and combined data analysis.
Getting ready
Ensure you have a running deployment on Elastic Cloud, which you have previously used to complete the recipes for monitoring the OpenTelemetry demo in Chapter 10. At this point, we need to confirm that the existing cluster is collecting application traces from the OpenTelemetry demo.
In Kibana, under your existing cluster, navigate to Observability | APM and verify that traces are being...
