The proxy can read data from SQL Server 2008, 2008R2, 2012, 2014, 2016, 2017 and 2019 versions by default and is customizable to read older SQL Server versions from SQL Server 2000 to 2005. Note that SQL Governor fully supports 64-bit version of SQL Server and partially supports 32-bit.

The proxy uses a comprehensive set of technology standard mechanisms and interfaces to interconnect other MS SQL Servers such as the Performance Monitor interface in .NET and MSSQL Server Data Management Views (DMV). The source server data is queried at a user-set interval and forwarded to the Web API, which then inserts the data into the SQL Governor database.
