the server could not find the metric <metrics-name> for services for HPA

[balajir24]

Hi, we want to create hpa based on custom metrics for azure storage queue count. I have configured Prometheus adapter and getting below response

 kubectl get --raw "/apis/custom.metrics.k8s.io/v1beta1"
{"kind":"APIResourceList","apiVersion":"v1","groupVersion":"custom.metrics.k8s.io/v1beta1","resources":[{"name":"jobs.batch/azure_queue_count","singularName":"","namespaced":true,"kind":"MetricValueList","verbs":["get"]}]}

Prometheus adapter Configuration:

prometheus:
  url: http://prom.monitoring.svc.cluster.local
  port: 80


rules:
  default: false
  custom:
  - seriesQuery: '{__name__=~"^messages_total$"}'
    resources:
      template: <<.Resource>>
    name:
            #matches: ^(.*)
      matches: ^(.*)
      as: "azure_queue_count"
    metricsQuery: messages_total{account_name="test",job="azure-svc-pushgateway",queue_name="test-jobs",resource_group="test-staging"}

and configured HPA. But HPA is not working and below is the error.

unable to fetch metrics from custom metrics API: the server could not find the metric azure_queue_count for pods

HPA configuration

apiVersion: autoscaling/v2beta1
kind: HorizontalPodAutoscaler
metadata:
  name: test-hpa
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: test-executor
  minReplicas: 1
  maxReplicas: 2
  metrics:
  - type: Object
    object:
      target:
        kind: Service
        name: test-executor
      metricName: azure_queue_count
      targetValue: "2"

please suggest on this.

Thanks in advance.

Hi, @balajir24 - support is not available in this repo, but you may want to look at https://github.com/kubernetes-sigs/prometheus-adapter#configuration and ask in that repo if that doesn't answer your question.
