Get summed CPU usage via Prometheus API

I have a prometheus query like below. Screenshot
(100 * avg by (instance) (rate(node_cpu_seconds_total{mode!="idle"}[1m])))

It give a sumarized CPU usage of an instance via the GUI

You have access to a prometheus demo instance here

And I want to have the same result via the prometheus API
curl 'http://localhost:9090/api/v1/query?query=MYQUERY

I tried & searched...
curl -g 'http://localhost:9090/api/v1/query?query=node_cpu_seconds_total'

Give me the CPU usage for all CPU individually...

curl -g 'http://localhost:9090/api/v1/query?query=(100 * avg by (instance) (rate(node_cpu_seconds_total{mode!="idle"}[1m])))'

Give me 400 Bad Request

Can someone give me a clue or help me to transform my request?
Thanks in advance

Solution

  • Use the following query:

    curl -g 'http://localhost:9090/api/v1/query?query=(100*avg%20by%20(instance)(rate(node_cpu_seconds_total{mode!=\"idle\"}[1m])))'
