You can use Logic Apps to collect and forward VMware syslogs from your Azure VMware Solution private cloud to any log management service of your choice. This approach allows for centralized log storage, analysis, and monitoring across your preferred tools. In this article, learn how to configure an Azure Logic Apps workflow to capture VMware syslogs and send them to your chosen log management service. :::image type="content" source="media/logs-to-logic-app/logic-app-arch-diagram.png" alt-text="Architecture flow of Azure VMware Solution logs to syslog server via Azure Logic Apps." border="false" lightbox="media/logs-to-logic-app/logic-app-arch-diagram.png"::: ## Prerequisites Verify you have an Azure VMware Solution private cloud set up that's streaming the syslogs to an Azure event hub instance within an Azure Event Hubs namespace. A valid instance of event hub within your Azure Event Hubs namespace is required. For setup guidance, visit [Configure VMware syslogs - Stream to Microsoft Azure Event Hubs](/azure/azure-vmware/configure-vmware-syslogs#stream-to-microsoft-azure-event-hubs). ## Create an Azure Logic Apps instance 1. From your Azure portal, select **Create a resource** > **Get Started**, then search for **Logic App**. Find the one called **Logic App**. From the **Create** drop down menu, select **Logic App**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-1.png" alt-text="Screenshot showing where to procure an instance of Azure Logic Apps." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-1.png"::: 2. Select the Host plan that makes the most sense for your consumption needs. In most cases, the **Workflow Service Plan** should meet your needs. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-2.png" alt-text="Screenshot showing which hosting option of Azure Logic Apps to select." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-2.png"::: 3. In the **Create Logic App (Workflow Service Plan)** > **Basics** tab, fill out the **Project Details**. - Enter the **Subscription** you want to use and the **Resource Group** chosen to house this instance. - Under **Instance Details**, enter the **Logic App name**, **Region**, and **Windows Plan**. > [!NOTE] > If your log management server is hosted in Azure (including within your Azure VMware Solution private cloud), ensure you select the same region as the Azure Virtual Network connected to your log management server. Otherwise, the integration fails. The default **Windows plan** is Workflow Standard WS1 (210 total ACU, 3.5 Gb memory, 1 vCPU) which should be enough to handle log volumes from large workloads. This option can always be adjusted later as needed. - After filling in the Project Details, select **Review + Create**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-3.png" alt-text="Screenshot showing the fields that need to be populated when creating an Azure Logic App." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-3.png"::: 4. Review the details of the Logic App instance, then select **Create**. Selecting **Create** initializes the deployment of the Logic App instance. Once complete, the deployment status reads *Your deployment is complete*. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-4.png" alt-text="Screenshot showing the summary of the Logic App creation." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-4.png"::: ## Set up the Azure Logic App workflow 1. Once deployed, navigate to the Logic App instance. Select **Workflows**, then select **Workflows**. Select **Add**, then select **Add from Template**. This action takes you to the template catalog available in Azure Logic Apps. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-5.png" alt-text="Screenshot showing the Workflows blade of Azure Logic App." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-5.png"::: 2.

The integration ensures the Logic App can communicate with endpoints that are only accessible within the virtual network. For example, if you're deploying your log management server on an Azure VMware Solution private cloud, you need an Azure Virtual Network that can be peered to the private cloud's network. ### Prerequisites - The Azure Virtual Network and the Azure Logic App must be in the same region. **Cross-region integration is not supported and will cause the setup to fail.** - Ensure there's an available subnet in your Azure Virtual Network for integration. For more information, visit [Add, change, or delete a virtual network subnet](../virtual-network/virtual-network-manage-subnet.md). ###Steps to integrate with your Azure Virtual Network 1. In the Azure Logic App, navigate to **Settings > Networking**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-21.png" alt-text="Screenshot showing where the Networking tab is in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-21.png"::: 2. Select the highlighted text that says **Not configured** next to **Virtual Network integration**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-22.png" alt-text="Screenshot showing where the Not Configured text is next to the Virtual Network option in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-22.png"::: 3. On the next screen, you'll see a message stating **No virtual network integration configured**. Select **Add virtual network integration** to integrate with the Azure Virtual Network that is connected to your log management server. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-23.png" alt-text="Screenshot showing where to add virtual network integration in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-23.png"::: 4. In the panel, choose the **Subscription** where your Azure Virtual Network lies, the **Virtual Network** you intend to use, and the **Subnet** you want to associate. Select **Connect** to integrate with your virtual network. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-24.png" alt-text="Screenshot showing where to add virtual network integration details in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-24.png"::: 5. Upon successful integration, the next screen will display the **Virtual Network Integration** details. You can always select **Disconnect** if you need to change the virtual network integration for your Logic App. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-25.png" alt-text="Screenshot showing where to manage virtual network integration in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-25.png"::: ## Adding certificates, updating HTTP headers, and configuring notifications ### Certificates If Azure Logic Apps requires the certificate from the log management server to be trusted, you might need to add the certificate to the Logic Apps instance to enable successful log transmission. Adding the certificate is a necessary step when using tools such as VMware Cloud Foundation Operations for Logs, for example. You can add the certificate to the Azure Logic App instance using the following approach: 1. Export the certificate from the log management server and save it as a .cer file. 2. In the Azure Logic App, navigate to **Settings > Certificates**. Navigate to the tab that says **Public key certificates (.cer)** and select **Add certificate**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-14.png" alt-text="Screenshot showing where to add the Public key certificate in the Azure Logic App instance." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-14.png"::: 3. Upload the certificate from Step 1 to **CER certificate file** and give the certificate a name, then select **Add**. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-15.png" alt-text="Screenshot showing where to add the Public key certificate in the Azure Logic App instance and giving it a name." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-15.png"::: 4. Once saved, copy the **Thumbprint** value. You need that for the environment variable in Step 5. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-16.png" alt-text="Screenshot showing where to copy the thumbprint of the newly added certificate." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-16.png"::: 5. Under **Settings**, select **Environment variables**, then select **Add**. The name of the environment variable to add is **WEBSITE_LOAD_ROOT_CERTIFICATES** and the value is the thumbprint you copied. Select **Apply** at the bottom of the panel to save the changes and **Apply** again at the bottom of the list of environment variables to apply these changes. The new environment variable should take effect. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-17.png" alt-text="Screenshot showing the successfully added environment variable." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-17.png"::: ### HTTP Headers By default, the **HTTP-Trigger-to-Log-Destination** trigger in the workflow you created has the following key-value pairs under Headers: - **Content-Type** : **application/json** The key-value pairs can work for log management tools such as VMware Cloud Foundation Operations for Logs. You might need to verify the log management server's ingestion cURL command to see if there are other headers that need to be added. If you see other headers, add them here and select **Save** so the logs can be ingested properly into your log management server. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-18.png" alt-text="Screenshot showing where headers can be modified inside the workflow." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-18.png"::: ### Run History The Run History section of a workflow in Azure Logic Apps provides a detailed log of workflow executions, which helps you track successful runs, diagnose failures, and troubleshoot issues. By reviewing the timestamps, status codes, and error messages, you can ensure your Azure VMware Solution syslog forwarding process is running smoothly and quickly identify any disruptions. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-20.png" alt-text="Screenshot showing Run History can be accessed." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-20.png"::: ### Configuring Notifications You notice in the last step of the workflow that there's an optional item called **Optional-Notification (README)**. You can replace this item with one of the available actions in Azure Logic Apps (like Outlook emails or Teams messages) to notify you in the event there's a failure that sends your logs to your log management server. :::image type="content" source="media/logs-to-logic-app/logs-to-logic-app-19.png" alt-text="Screenshot showing where notifications can be added inside the workflow." border="false" lightbox="media/logs-to-logic-app/logs-to-logic-app-19.png":::
