ServerInternals is licensed corporate-wide or on a per computer basis.
There are three licence types available; corporate-wide, full and agent-only.
A single corporate licence allows unlimited usage across all servers and workstations owned or operated by a single legal entity.
The full licence, which is intended for workstations, allows the entire ServerInternals suite to be installed. The agent-only licence, which is intended for servers, only allows the collection agent to be installed.
No additional licence is required for the systems to which ServerInternals connects via WMI or WinRM and which are not running the collection agent - a licence is only required for each computer running the ServerInternals software itself.
Typically an organisation that does not choose the corporate-wide licence will require one full licence for each individual who is using the software to understand system behaviour and diagnose issues, and one agent licence for each server on the network.
For per computer licences, when you purchase your licences, you’ll recieve one serial number for each licence purchased, and each serial number is used to activate the software on a single computer.
Once activated, ServerInternals can then be used to connect to an unlimited number of servers to display diagnostic information.
