+### Configuration
+
+To configure this feature for an Azure Function App not on a consumption plan, add environment variables in App settings. To review available configurations, see [Configuration options: Azure Monitor Application Insights for Java](../app/java-standalone-config.md). 
+
+For Azure Functions on a consumption plan, the available configuration options are limited to WEBSITE_SITE_NAME, APPLICATIONINSIGHTS_INSTRUMENTATION_LOGGING_LEVEL, and APPLICATIONINSIGHTS_SELF_DIAGNOSTICS_LEVEL in order to take advantage of the consumption plan warmup pool. For more configurations on a consumption plan Function, deploy your own agent and see [Distributed Tracing for Java Functions](https://github.com/Azure/azure-functions-java-worker/wiki/Distributed-Tracing-for-Java-Azure-Functions#customize-distribute-agent).
+
+Deploying your own agent results in a longer cold start implication for consumption plan Functions.

 ### Troubleshooting
 
 Your Java functions might have slow startup times if you adopted this feature before February 2023. From the function app **Overview** pane, go to **Configuration** in the left-hand side navigation menu. Then select **Application settings** and use the following steps to fix the issue.

 ## Distributed tracing for Python function apps
 
-To collect telemetry from services such as Requests, urllib3, httpx, PsycoPG2, and more, use the [Azure Monitor OpenTelemetry Distro](./opentelemetry-enable.md?tabs=python). Tracked incoming requests coming into your Python application hosted in Azure Functions will not be automatically correlated with telemetry being tracked within it. You can manually achieve trace correlation by extract the TraceContext directly as shown below:
