How can I add a custom static label to a Prometheus query\metric?

Question

Ok, so I have this query right here container_cpu_reserved which gives me the following metric:

container_cpu_reserved{datacenter="dev-01", instance="worker-02", job="nomad", node_class="core", node_id="xxxxxxxxxxxxxx", node_scheduling_eligibility="eligible", node_status="ready"}

I want to add 2 labels more to this query which would be cloud="aws" and account_id="0123456789"

How can I do this? (sorry I'm pretty new to Prometheus)

Answer 1

You could add labels directly in Query, Add two label_replace functions arround your PromQL:

label_replace(       
    label_replace( 

        container_cpu_reserved,

    "cloud", "aws", "instance", ".*")           
,"account_id", "0123456789", "instance", ".*")

But it seems to me that you asked the wrong question (that's why you got this answer).

If you wish to add this labels to all PODs of your Deployment, the right way is to add labels to Deployment manifest:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    cloud: aws
    account_id: 0123456789
