Splunk Observability Cloud uses OpenTelemetry to correlate telemetry types. To enable this ability, your telemetry field names or metadata key names must exactly match the metadata key names used by both OpenTelemetry and Splunk Observability Cloud.

Related Content works out-of-the-box when you deploy the Splunk Distribution of the OpenTelemetry Collector with its default configuration to send your telemetry data to Splunk Observability Cloud. With the default configuration the Collector automatically maps your metadata key names correctly. To learn more about the Collector, see :ref:`otel-intro`.

.. caution:: If you don't use the Splunk Distribution of OpenTelemetry Collector, or you use a non-default configuration, your telemetry data might have metadata key names that are not consistent with those used by Splunk Observability Cloud and OpenTelemetry, and Related Content might not work. In that case, you must change your metadata key names.

Configure the Collector to enable APM Related Content
If you're using the Splunk Distribution of OpenTelemetry Collector, another distribution of the Collector, or the :ref:`upstream Collector <using-upstream-otel>` and want to ensure Related Content in Splunk Observability Cloud behaves correctly, verify that the SignalFx exporter is included in your configuration. This exporter aggregates the metrics from the ``hostmetrics`` receiver and must be enabled for the ``metrics`` and ``traces`` pipelines.

The Collector uses the correlation flag of the SignalFx exporter to make relevant API calls to correlate your spans with the infrastructure metrics. This flag is enabled by default. To adjust the correlation option further, see the SignalFx exporter's options at :ref:`signalfx-exporter-settings`.
