 There are two ways to view a stream of log files being generated by your function executions.
 
-* **Live Metrics Stream (recommended)**: when your function app is [connected to Application Insights](configure-monitoring.md#enable-application-insights-integration), you can view log data and other metrics in near real-time in the Azure portal using [Live Metrics Stream](/azure/azure-monitor/app/live-stream). Use this method when monitoring functions running on multiple-instances and supports all plan types. This method uses [sampled data](configure-monitoring.md#configure-sampling).
+## [Live Metrics](#tab/live-metrics)
 
-* **Built-in log streaming**: the App Service platform lets you view a stream of your application log files. This is equivalent to the output seen when you debug your functions during [local development](functions-develop-local.md) and when you use the **Test** tab in the portal. All log-based information is displayed. For more information, see [Stream logs](../app-service/troubleshoot-diagnostic-logs.md#stream-logs). This streaming method supports only a single instance, and can't be used with an app running on Linux in a Consumption plan. When your function is scaled to multiple instances, data from other instances isn't shown using this method.

-Log streams can be viewed both in the portal and in most local development environments. 
+>[!IMPORTANT]
+>By default, the Live Metrics stream includes logs from all apps connected to a given Application Insights instance. When you have more than one app sending log data, you should [filter your log stream data](/azure/azure-monitor/app/live-stream#filter-by-server-instance).

+Log streams can be viewed both in the portal and in most local development environments. The way that you enable and view streaming logs depends on your log streaming method, either Live Metrics or built-in. 
 
-This connects your app to the log streaming service and application logs are displayed in the window. You can toggle between **Application logs** and **Web server logs**.

->[!NOTE] 
->Because built-in log streaming isn't yet enabled for function apps running on Linux in a Consumption plan, you need to instead enable the [Live Metrics Stream](/azure/azure-monitor/app/live-stream) to view the logs in near-real time. 
+This connects your app to the log streaming service and application logs are displayed in the window. You can toggle between **Application logs** and **Web server logs**.
