PerformanceMonitor is a free and open-source tool designed to help you keep an eye on your SQL Server’s health and speed. Whether you run a large server setup or just want to check one database on your computer, PerformanceMonitor gives you clear information about how well your system is doing.
It comes in two versions:
- Full Edition: This version is installed on a server and can check up to 30 different parts (collectors) of your SQL Server's performance.
- Lite Edition: A smaller version you can run by itself on your PC using DuckDB, a simple database engine.
PerformanceMonitor also includes a built-in MCP server that can work with AI for advanced data analysis. But you don't need to know anything about AI to use the basic features.
You don’t need to be a tech expert or understand programming to use PerformanceMonitor. This software is made for people who want to:
- See how their SQL Server is performing.
- Spot problems early before they cause downtime.
- Get simple reports about server health.
- Use a free tool without complicated setup.
If you know how to download software and follow step-by-step instructions, this guide will help you get started.

- Operating System: Windows 10 or later, or any recent Linux version.
- Processor: At least 2 GHz for smooth performance.

In the Full Edition, collectors gather information from different parts of your SQL Server. You can:
- Enable or disable collectors to focus on areas you care about.

- View historic trends for better insight.
Start with the default collectors, and explore more once you get comfortable.

- Make sure your PC and SQL Server are on the same network.
- Check that the SQL Server is turned on.
- Verify your username and password.
- Restart PerformanceMonitor.
