PromQL for Mere Mortals

PromQL can feel intimidating at first for those new to the Prometheus ecosystem, but it is an essential skill to learn when starting out monitoring and alerting in the Prometheus ecosystem.

In this beginner-focused, demo-driven talk we will walk through the thought processes, mental models and coping strategies we can use to tame PromQL and effectively query metrics data.

We will demystify instant vector selectors from range vector selectors, understand how aggregate functions work, and, time-permitting, even touch on some PromQL engine internals.
