Comprehensive Postgres observability: is your database healthy, and will it stay that way?
A database has to stay durable, available, and fast, and the failures that break those promises rarely page you until it's too late. Here's how comprehensive Postgres observability tells you your database is healthy now and will keep performing.

Reproducing split brain on CloudNativePG
We partitioned the primary of a default CloudNativePG cluster and measured how long it kept accepting writes after a replacement was promoted, what that did to the data, and which settings shrink the window.

It was surprisingly hard to break CloudNativePG replication
I tried to make a Postgres replica fall behind by cutting it off from its primary with Chaos Mesh. It stubbornly refused to lag. Here's the investigation, the logs, and the proof from CloudNativePG's source that a replica has a second, hidden WAL source.

Let's break autovacuum in Postgres: reproducing failures to make it observable
Every Postgres runs autovacuum and almost nobody monitors it properly. Let's reproduce the common ways it fails and see how Coroot turns each one into a clear, actionable finding.

The hard part of AI root cause analysis is no longer the model
We ran one real incident through eleven LLMs. The reasoning turned out to be the easy part; the real challenge is the harness that feeds the model the right context.

Observability on Windows, before eBPF is production-ready
Coroot's agent now runs on Windows. The story of building it on ETW instead of eBPF: what came easy, what was hard, and what we left for later.

Zero-config Go heap profiling
How we added continuous Go heap profiling to coroot-node-agent without requiring any code changes, pprof endpoints, or annotations, by reading runtime.mbuckets directly from process memory.

Profiling Java apps: breaking things to prove it works
We added async-profiler support to Coroot for Java CPU, memory, and lock contention profiling with no code changes—then broke things to prove it works.
