PromQL Compatibility Testing - Verifying Vendor Claims for End User Benefit - Julius Volz, PromLabs

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Prometheus' query language PromQL is one of the most important interfaces in the Prometheus ecosystem. Organizations rely on it to build their dashboards, critical alerting, and automation. With Prometheus becoming more popular, we are seeing more and more PromQL implementations outside of Prometheus itself, both in open-source projects and in hosted monitoring providers. While this is great, not all implementations that claim to be PromQL-compatible actually implement PromQL correctly. To avoid user confusion, ecosystem fragmentation, and vendor lock-in, we want to encourage fully compatible implementations and at the same time increase transparency around the actual compatibility of different solutions.

In this talk, Prometheus co-founder Julius Volz will present an open-source PromQL compliance testing suite that can shine a light on the compatibility situation. He will also outline test results of actual vendor PromQL implementations, dive into some of the encountered behavioral differences, and give recommendations for anyone wanting to implement PromQL in their own product or service.
