The download page requests a first name, last name and work email to access downloads.

Paessler PRTG Database Monitoring tracks database availability, errors, and query performance across Microsoft SQL Server, MySQL, PostgreSQL, Oracle, Azure SQL Database, AWS RDS, and ODBC/ADO-compatible databases. Its sensors measure complete-request time and query execution time separately in milliseconds. You can run custom SQL queries on a schedule and map results to monitoring channels. PRTG can flag connection timeouts, authentication failures, service interruptions, and query-validated errors; threshold alerts can go by email, SMS, push notification, syslog, or webhook.

Azure SQL Database and AWS RDS sensors collect metrics through Azure Monitor and AWS CloudWatch APIs without an agent on the database host. Scan intervals are configurable, with Paessler recommending five minutes for production monitoring. Backup checks use custom queries against backup history tables or file timestamps and require query-level setup. PRTG is offered as a Windows download or cloud-hosted service. Platforms listed include web, Windows, Android, iOS, and self-hosted deployment. A free plan covers up to 100 sensors; paid plans start at $200/mo (annual), and the free trial lasts 30 days.
