SQL Sentry

Breakthrough SQL Server Performance Monitoring

SQL Sentry is the leading solution for SQL Server performance monitoring

Stay out of the weeds, save time, and escape the tyranny of the urgent. Collect and present the most actionable performance metrics and alerts, see essential events and cross-reference them using an Outlook-style calendar. Quickly resolve issues by doing detailed analysis in the same tool you use for SQL monitoring and alerting.

Our performance dashboard, which includes a patented view of storage performance, gives you a detailed analysis of high-impact queries as well as query plans presented through our popular Plan Explorer functionality.
