CloudSQL for MySQL gives you CPU graphs and connection counts. When something goes wrong you need to know which exact query ran for 3 seconds at 14:07:43, which user triggered it, and which threads were competing for locks. Threads Monitoring captures every query from performance_schema as it executes, with no agents and no schema changes, and produces two self-contained HTML reports for immediate investigation.

Taming JVM Memory on JDK 25 — Part 2: OOMs While the Heap Is Flat
Part 1 fixed the collector and sized the heap. This part covers what happens next — native memory leaks from glibc arenas, RSS vs heap diagnosis, and the fixes that actually work.
engineeringContext as Infrastructure: How We Stopped Burying Business Logic in System Prompts
We were building AI agents for real marketing workflows when we noticed a pattern: every production failure traced back to a system prompt, not the model.
