SQL Diagnostic Manager vs. Sifflet

IDERA SQL Diagnostic Manager (SQL DM) is a leading SQL Server performance monitoring, diagnostics, and optimization platform for database administrators managing on-premises, cloud, and hybrid environments. Now in version 14, SQL Diagnostic Manager delivers enterprise-grade visibility into SQL Server health, availability, query performance, and resource utilization — with built-in AI-powered query and workload index optimization introduced in the latest release.

Sifflet is the control plane for Data and AI. Data teams spend too much time firefighting — bad data reaches the business before anyone catches it, root cause takes days, and the fix is invisible to the stakeholders who were burned. The result is a slow erosion of trust in every dashboard, report, and AI output the company relies on. We give data teams one layer that catches issues across the full stack, explains exactly where they came from, and shows how to resolve them — before the CFO sees the wrong number.
