 In Application Insights, you can enable enhanced telemetry collection for your Standard logic app resource and then view the collected data after your workflow finishes a run. This capability gives you a simplified experience to discover insights about your workflows and more control over filtering events at the data source, which helps you reduce storage costs. These improvements focus on real-time performance metrics that provide insights into your system's health and behavior. This can help you with proactively detecting and resolving issues earlier.

+You can also set up your Standard logic app resource to export log and trace data in [OpenTelemetry format](https://opentelemetry.io/). By default, this telemetry data is sent to Application Insights using the Application Insights SDK. However, you can choose to export this data using OpenTelemetry semantics. While you can still use an OpenTelemetry format to send your data to Application Insights, you can also export the same data to any other OpenTelemetry-compliant endpoint. OpenTelemetry provides the following benefits for your logic app:
+
+- Correlation across traces and logs generated at the host and in your application code.
+- Consistent, standards-based generation for exportable telemetry data.
+- Integration with other providers that can consume OpenTelemetry-compliant data.
+- Enable OpenTelemetry at the logic app resource level, both in host configuration (host.json) and in your logic app project.

+## Set up OpenTelemetry through Visual Studio Code
+
+You can configure your Standard logic app so that the Azure Logic Apps (Standard) runtime emits telemetry in [OpenTelemetry format](https://opentelemetry.io/). However, before you set up OpenTelemetry, consider the following limitations in the current release:
+
+- Only the following triggers currently support OpenTelemetry outputs: HTTP, Service Bus, and Event Hubs
+
+- Metrics export is currently unsupported.
+
+To set up OpenTelemetry capability, follow these steps:
+
+1. In your Standard logic app project, open the **host.json** file at the project root level.
+
+1. In the **host.json** file, at the root level, add the following **telemetryMode** setting with the **OpenTelemetry** value, for example:
+
+   ```json
+   {
+       "version": "2.0",
+       "extensionBundle": {
+           "id": "Microsoft.Azure.Functions.ExtensionBundle.Workflows",
+           "version": "[1.*, 2.0.0)"
+       },
+       "telemetryMode": "OpenTelemetry"
+   }
+   ```
+
+   When you enable OpenTelemetry in the **host.json** file, your logic app exports telemetry based on the OpenTelemetry-supported app settings that you define in the environment.
+
+1. Open the **local.settings.json** file at the project root level, add the following app settings:
+
+   | App setting | Description |
+   |-------------|-------------|
+   | **OTEL_EXPORTER_OTLP_ENDPOINT** | The online transaction processing (OTLP) exporter endpoint URL for where to send the telemetry data. |
+   | **OTEL_EXPORTER_OTLP_HEADERS** (optional) | A list of headers to apply to all outgoing data. Commonly used to pass authentication keys or tokens to your observability backend. |
+
+1. If your OpenTelemetry endpoint requires other OpenTelemetry-related settings, include these settings in the app settings too.
+
+For more information, see the following documentation:
