Prometheus - Convert cpu_user_seconds to CPU Usage %?

Question

I\'m monitoring docker containers via Prometheus.io. My problem is that I\'m just getting cpu_user_seconds_total or cpu_system_seconds_total.

Answer 1

For Windows Users - wmi_exporter

100 - (avg by (instance) (irate(wmi_cpu_time_total{mode="idle"}[2m])) * 100)

Answer 2

Rate returns a per second value, so multiplying by 100 will give a percentage:

rate(container_cpu_user_seconds_total[30s]) * 100

Answer 3

I also found this way to get CPU Usage to be accurate:

100 - (avg by (instance) (irate(node_cpu_seconds_total{job="node",mode="idle"}[5m])) * 100)
