Configure the Log Analytics agent for Windows computers in a hybrid environment

Azure Log Analytics can collect data directly from your physical or virtual Windows computers into a single repository for detailed analysis and correlation. Log Analytics can collect data from a datacenter or other cloud environment. This quickstart shows you how to configure and collect data from your Windows computer with a few easy steps. For information about Azure Windows VMs, see Collect data about Azure virtual machines.

To understand the supported configuration, see Supported Windows operating systems and Network firewall configuration.

If you don't have an Azure subscription, create a free account before you begin.

  2. Select Create, and then provide these details:

    • Enter a name for the new Log Analytics Workspace. Something like DefaultLAWorkspace.

    • Select a Subscription to link to. If the default isn't the one you want to use, select another one from the list.

    • For the Resource Group, select an existing resource group that contains one or more Azure virtual machines.

    • Select the Location your VMs are deployed to. Here's a list of regions in which Log Analytics is available.

    • If you're creating a workspace in a subscription that you created after April 2, 2018, the workspace will automatically use the Per GB pricing plan. You won't be able to select a pricing tier. If you're creating a workspace in a subscription that you created before April 2, 2018, or in a subscription that was tied to an existing EA enrollment, select the pricing tier that you want to use. See the Log Analytics pricing details for information about tiers.
