PromQL Instruction?

I’m really struggling learning the PromQL for Prometheus. Can anyone point me to some resources to help me learn it? I want to be able to confidently write queries such as if the value changes by more than 100 in the past hour, send and alert.

Hi @michaelblack - @emiltullstedt did a great Introduction to PromQL blog post that covers the basics and includes some additional resources: https://grafana.com/blog/2020/02/04/introduction-to-promql-the-prometheus-query-language/
