Insightd is pretty simple and can run on any Windows or Linux server behind your firewall that:

• Has significant uptime;
• Has outbound connectivity to the Metric Insights server;
• Has network connectivity to your internal data sources.

If you'd like to connect to Microsoft SQLServer, for example, you could install Insightd on the SQLServer machine itself, or any other machine in your network that can already query your SQLServer database.
