Spiceworks lets you stay on top of performance so that you’ll detect issues before your users do… all for free! With Spiceworks SQL Server Monitoring, you can monitor SQL Server size, connection, speed & more.
Spiceworks automatically retrieves information about SQL databases on your network (SQL Server 2005 and higher). Health checks are run every minute to ensure info is always accurate and up-to-date. A fully customizable dashboard makes it easy to monitor the SQL info you choose. You can create multiple widgets to monitor SQL server data from each installation or even create an entire dashboard page specifically for monitoring all aspects of your SQL server’s health.
