Quickstart: Set up a Log Analytics workspace

Note

The Basic, Standard, and Enterprise plans will be deprecated starting from mid-March, 2025, with a 3 year retirement period. We recommend transitioning to Azure Container Apps. For more information, see the Azure Spring Apps retirement announcement.

The Standard consumption and dedicated plan will be deprecated starting September 30, 2024, with a complete shutdown after six months. We recommend transitioning to Azure Container Apps. For more information, see Migrate Azure Spring Apps Standard consumption and dedicated plan to Azure Container Apps.

This quickstart explains how to set up a Log Analytics workspace in Azure Spring Apps for application development.

Log Analytics is a tool in the Azure portal that's used to edit and run log queries with data in Azure Monitor Logs. You can write a query that returns a set of records and then use features of Log Analytics to sort, filter, and analyze those records. You can also write a more advanced query to do statistical analysis and visualize the results in a chart to identify particular trends. Whether you work with the results of your queries interactively or use them with other Azure Monitor features, Log Analytics is the tool that you use to write and test queries.

You can set up Azure Monitor Logs for your application in Azure Spring Apps to collect logs and run log queries via Log Analytics.

Prerequisites

Complete the previous quickstart in this series: Provision an Azure Spring Apps service instance.

Portal

Create a Log Analytics workspace

To create a workspace, follow the steps in Create a Log Analytics workspace.

Set up Log Analytics for a new service

In the wizard for creating an Azure Spring Apps service instance, you can configure the Log Analytics workspace field with an existing workspace or create one.

Set up Log Analytics for an existing service

1. In the Azure portal, go to the Diagnostic settings section under Monitoring.

   

2. If no settings exist, select Add diagnostic setting. You can also select Edit setting to update existing settings.

3. Fill out the form on the Diagnostic setting page:

   • Diagnostic setting name: Set a unique name for the configuration.
   • Logs > Categories: Select ApplicationConsole and SystemLogs. For more information on log categories and contents, see Diagnostic settings in Azure Monitor.
   • Destination details: Select Send to Log Analytics workspace and specify the Log Analytics workspace that you created previously.

   

4. Select Save.

CLI

Create a Log Analytics workspace

Use the following commands to create a Log Analytics workspace and get the workspace ID:

az monitor log-analytics workspace create \
    --workspace-name <new-workspace-name> \
    --resource-group <your-resource-group> \
    --location <your-service-region> \
    --query id --output tsv

If you have an existing workspace, you can get the workspace ID by using the following commands:

az monitor log-analytics workspace show \
     --resource-group <your-resource-group> \
     --workspace-name <workspace-name> \
     --query id --output tsv

Set up Log Analytics for a new service

Setting up for a new service isn't applicable when you're using the Azure CLI.

Set up Log Analytics for an existing service

1. Get the instance ID for the Azure Spring Apps service:

   az spring show \
       --name <spring-cloud-service-name> \
       --resource-group <your-resource-group> \
       --query id --output tsv
   

2. Configure the diagnostic settings. For more information on log categories and contents, see Diagnostic settings in Azure Monitor.

   az monitor diagnostic-settings create \
       --name "<new-name-for-settings>" \
       --resource "<service-instance-id>" \
       --workspace "<workspace-id>" \
       --logs '[
            {
                "category": "ApplicationConsole",
                "enabled": true,
                "retentionPolicy": {
                    "enabled": false,
                    "days": 0
                }
            },
            {
                "category": "SystemLogs",
                "enabled": true,
                "retentionPolicy": {
                    "enabled": false,
                    "days": 0
                }
            }
        ]'
   

Clean up resources

If you plan to continue working with subsequent quickstarts and tutorials, you might want to leave these resources in place. When no longer needed, delete the resource group, which deletes the resources in the resource group. To delete the resource group by using Azure CLI, use the following commands:

echo "Enter the Resource Group name:" &&
read resourceGroupName &&
az group delete --name $resourceGroupName &&
echo "Press [ENTER] to continue ..."
