This article shows you how to create a Log Analytics workspace. When you collect logs and data, the information is stored in a workspace. A workspace has a unique workspace ID and resource ID. The workspace name must be unique for a given resource group. After you've created a workspace, configure data sources and solutions to store their data there.
You need a Log Analytics workspace if you collect data from:
Azure resources in your subscription.
On-premises computers monitored by System Center Operations Manager.
Device collections from Configuration Manager.
Diagnostics or log data from Azure Storage.
Prerequisites
To create a Log Analytics workspace, you need an Azure account with an active subscription. You can create an account for free.
You need Microsoft.OperationalInsights/workspaces/write permissions to the resource group where you want to create the Log Analytics workspace, as provided by the Log Analytics Contributor built-in role, for example.
Create a workspace
Portal
PowerShell
Azure CLI
Resource Manager template
Use the Log Analytics workspaces menu to create a workspace.
In the Azure portal, enter Log Analytics in the search box. As you begin typing, the list filters based on your input. Select Log Analytics workspaces.
Use an existing Resource Group or create a new one.
Provide a name for the new Log Analytics workspace, such as DefaultLAWorkspace. This name must be unique per resource group.
Select an available Region. For more information, see which regions Log Analytics is available in. Search for Azure Monitor in the Search for a product box.
Select Review + Create to review the settings. Then select Create to create the workspace. A default pricing tier of pay-as-you-go is applied. No charges will be incurred until you start collecting enough data. For more information about other pricing tiers, see Log Analytics pricing details.
Troubleshooting
When you create a workspace that was deleted in the last 14 days and in soft-delete state, the operation could have a different outcome depending on your workspace configuration:
If you provide the same workspace name, resource group, subscription, and region as in the deleted workspace, your workspace will be recovered including its data, configuration, and connected agents.
Workspace names must be unique for a resource group. If you use a workspace name that already exists, or is soft deleted, an error is returned. To permanently delete your soft-deleted name and create a new workspace with the same name, follow these steps:
Create a new workspace by using the same workspace name.
Next steps
Now that you have a workspace available, you can configure collection of monitoring telemetry, run log searches to analyze that data, and add a management solution to provide more data and analytic insights. To learn more:
Log Analytics is a tool in the Azure portal that's used to edit and run log queries against data in the Azure Monitor Logs store. You might write a simple query that returns a set of records and then use features of Log Analytics to sort, filter, and analyze them.

Go to the Log Analytics workspaces menu in the Azure portal and select Tables. The tables in the workspace will appear. Select Create > New custom log (DCR based).
Your design should always start with a single workspace to reduce the complexity of managing multiple workspaces and in querying data from them. There are no performance limitations from the amount of data in your workspace. Multiple services and data sources can send data to the same workspace.
Azure Monitor Metrics can only store numeric data in a particular structure, whereas Azure Monitor Logs can store a variety of data types that have their own structures. You can also perform complex analysis on Azure Monitor Logs data by using log queries, which can't be used for analysis of Azure Monitor Metrics data.
The default pricing for Log Analytics is a pay-as-you-go model that's based on ingested data volume and data retention. Each Log Analytics workspace is charged as a separate service and contributes to the bill for your Azure subscription.
Application Insights provides real-time monitoring and user-centric insights, while Log Analytics offers a comprehensive log management and analysis solution. Together, they enable you to identify bottlenecks, troubleshoot issues, and optimize your application for better user experience.
To access Azure Log Analytics, you need to sign in to the Azure portal with your Azure account.Once you're signed in, you can access Log Analytics by selecting it from the list of services in the portal. To use Log Analytics, you need to create a Log Analytics workspace in your Azure subscription.
As you might have guessed, the data is stored in datacenters of the cloud (in the same region you have set up your LA workspace). Data is stored in the OMS repository as records.
To send customized JSON data to the Log Analytics Workspace, you can use a custom app to deliver it over the Data Ingestion API. Create a new data collection endpoint and a data collection rule by selecting the custom text logs type with some random file pattern such as '/' .
To edit the target region where the Log Analytics workspace will be deployed, change the location property under resources in the online editor. To get region location codes, see Data residency in Azure. The code for a region is the region name with no spaces. For example, Central US should be centralus .
First, you'll need to import the necessary packages from Pulumi and set up the Azure provider. Then, you'll create a LinkedStorageAccount resource, specifying the workspace name, resource group, data source type, and storage account IDs you want to associate.
