 This change will configure otel-agent pods to send span data to coralogix-opentelemetry-gateway deployment using [loadbalancing exporter](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/exporter/loadbalancingexporter). Make sure to configure enough replicas and resource requests and limits to handle the load. Next, you will need to configure [tail sampling processor](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/tailsamplingprocessor)  policies with your custom tail sampling policies.
 
+When running in Openshift make sure to set `distribution: "openshift"` in your `values.yaml`.

 ### Enabling scraping of Prometheus custom resources (`ServiceMonitor` and `PodMonitor`)
 
 If you're leveraging the Prometheus Operator custom resources (`ServiceMonitor` and `PodMonitor`) and you would like to keep using them with the OpenTelemetry collector, you can enable the scraping of these resources by a special, optional component called target allocator. This feature is disabled by default and can be enabled by setting the `opentelemetry-agent.targetAllocator.enabled` value to `true` in the `values.yaml` file.
