PromQL Basics

In this lesson, you will learn the basics of Prometheus' query language—PromQL. This includes queries using the metric name and then filtering it using labels.

Return all time series with the metric node_cpu_seconds_total:

node_cpu_seconds_total

Return all time series with the metric node_cpu_seconds_total and the given job and mode labels:

node_cpu_seconds_total{job="node-exporter", mode="idle"}

Return a whole range of time (in this case 5 minutes) for the same vector, making it a range vector:

node_cpu_seconds_total{job="node-exporter", mode="idle"}[5m]

Query job that end with -exporter:

node_cpu_seconds_total{job=~".*-exporter"}

Query job that begins with kube:

container_cpu_load_average_10s{job=~"^kube.*"}
