Change pricing tier for Log Analytics workspace

Each Log Analytics workspace in Azure Monitor can have a different pricing tier. This article describes how to change the pricing tier for a workspace and how to track these changes.

Note

This article describes how to change the commitment tier for a Log Analytics workspace once you determine which commitment tier you want to use. See Azure Monitor Logs pricing details for details on how commitment tiers work and Azure Monitor cost and usage for recommendations on the most cost effective commitment based on your observed Azure Monitor usage.

Permissions required

To change the pricing tier for a workspace, you must be assigned to one of the following roles:

• Log Analytics Contributor role.
• A custom role with Microsoft.OperationalInsights/workspaces/*/write permissions.

Changing pricing tier

Azure portal

Use the following steps to change the pricing tier of your workspace using the Azure portal.

1. From the Log Analytics workspaces menu, select your workspace, and open Usage and estimated costs. This displays a list of each of the pricing tiers available for this workspace.

2. Review the estimated costs for each pricing tier. This estimate assumes that the last 31 days of your usage is typical. Choose the tier with the lowest estimated cost.

3. Click Select if you decide to change the pricing tier after reviewing the estimated costs.

4. Review the commitment message in the popup that "Commitment Tier pricing has a 31-day commitment period, during which the workspace cannot be moved to a lower Commitment Tier or any Consumption Tier" and click Change pricing tier to confirm.

Azure Resource Manager

To set the pricing tier using an Azure Resource Manager, use the sku object to set the pricing tier and the capacityReservationLevel parameter if the pricing tier is capacityresrvation. For details on this template format, see Microsoft.OperationalInsights workspaces

The following sample template sets a workspace to a 300 GB/day commitment tier. To set the pricing tier to other values such as Pay-As-You-Go (called pergb2018 for the SKU), omit the capacityReservationLevel property.

{
  "$schema": https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#,
  "contentVersion": "1.0.0.0",
  "resources": [
    {
      "name": "YourWorkspaceName",
      "type": "Microsoft.OperationalInsights/workspaces",
      "apiVersion": "2020-08-01",
      "location": "yourWorkspaceRegion",
      "properties": {
                    "sku": {
                      "name": "capacityreservation",
                      "capacityReservationLevel": 300
                    }
      }
    }
  ]
}

See Deploying the sample templates if you're not familiar with using Resource Manager templates.

Tracking pricing tier changes

Changes to a workspace's pricing tier are recorded in the Activity Log. Filter for events with an Operation of Create Workspace. The event's Change history tab will show the old and new pricing tiers in the properties.sku.name row. To monitor changes the pricing tier, create an alert for the Create Workspace operation.
