Change pricing tier for Log Analytics workspace

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.

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.
