One software license is required per server per year.

The Redgate Monitor License allows you to monitor one of the following per Server License.

• x1 server (Multiple instances)
  You will require one license per server, regardless of how many instances are on that server.
• x5 Azure SQL Databases
  One Redgate Monitor license allows you to monitor up to 5 Azure SQL Databases.
• x1 Cloud (PaaS) instance
  You can monitor 1 x server instance hosted on either Microsoft Azure Managed Instances or Amazon RDS with one Redgate Monitor license.
• x1 Cluster node
  Redgate Monitor supports monitoring Windows failover clusters. You will need one license for each node in a monitored cluster. Other proprietary clustering server systems aren't supported, and might not behave as expected.
• x1 Virtual machine
  You can monitor database instances running on Virtual Machines (VMs). One Redgate Monitor license is required per VM being monitored.

For example, if you have five physical servers you want to monitor, each running a Windows operating system with SQL Server, you will need a five-server license of Redgate Monitor. Licensing for Redgate Monitor depends on the number of servers you wish to monitor. You only need to license each server you wish to monitor, even if you have more than one instance of SQL Server running and even if you have a multi-processor server.
