The Microsoft SQL Server Health and History Tool (SQLH2) allows you to collect information from instances of SQL Server, store this information, and run reports against the data in order to determine how SQL Server is being used.
SQLH2 collects four main types of information:
1. Feature Usage – What services/features are installed, running and level of workload on the service.
2. Configuration Settings – Machine, OS and SQL configuration settings, SQL instance and database metadata.
3. Uptime of the SQL Server service
4. Performance Counters (optional) – Used to determine performance trends
