Observe live SQL queries in Go with DTrace

Read Original

This technical article explains a method for observing live SQL queries in Go programs using DTrace. It details how to hook into the `database/sql` package's `QueryContext` function to print the raw query string and then progressively decode variadic arguments (strings and arrays) by inspecting Go runtime memory and registers, all without restarting the application.
