In this section, we are going to learn how we can monitor an AD environment using OMS. Before we start, we need the following:

• Valid OMS subscription: OMS has different levels of subscription. It depends on the OMS services you use and amount of data uploaded daily. It does have a free version which provides 500 MB daily upload and 7-day data retention.
• Direct connection to OMS: In this demo, I am going to use direct OMS integration via Microsoft Monitoring Agent.
• Domain administrator account: In order to install the agent on the domain controllers, we need to have domain administrator privileges.
