Our own tools for SQL Server.
For more than ten years we have been developing our own software for working on SQL Server workloads, and we keep revising it. Our engineers use it in troubleshooting, analysis and ongoing support.
Evidence instead of gut feeling.
Each tool answers its own question. What they share is the aim of backing every statement with evidence.
PSG QX
The execution history as a dataset: from the time course through plans and statistics to the line in the code. Local and deterministic.
Beneath the curve → EvidenceQX Recorder
Captures the evidence of sporadic problems. If the problem occurs at night, the data is there in the morning.
In performance analysis → ContinuousMX AIOps
Data collection and analysis for environments under ongoing support, with traceable rules and statistical methods. The foundation for PSG MX.
To PSG MX → For software vendorsQX Fleet
Detect patterns across all installations of a piece of software and assess releases in production, as a guided program with our engineers.
For software vendors → Open sourceT-Lift
Our precompiler for T-SQL: catch-all procedures become parameterized dynamic SQL with stable plans. Apache 2.0.

Led by engineers
Our tools are the working equipment of our engineers in troubleshooting, analysis and ongoing support. People are accountable for the finding.
Local and traceable
The analyses run locally, without cloud or AI services. We define which data goes where for each engagement.
Grown from practice
From PSG MX, then written in C#, to PSG QX: every generation grew out of real cases. On its origins →
Let's talk about your environment.
In the first conversation we clarify which question you want answered and which tool helps with it.
