Issue with Alertlist panel not filtering correctly

Grafana Alerting
1

I’m using Unified Alerting with Grafana open source v9.1.6 self-deployed in a k8s cluster

I installed kube-prometheus, and as a result I have hundred of rules and alerts, and I would like to visualize them in our Grafana dashboards. This is what the alerting section looks like for a firing alert:

Key point here is the top 3 labels. Those do not appear in the Alertlist panel, which means I’m unable to filter by the cluster tag:

As you can see, “CPUThrottling” alert appears twice because I’m currently monitoring two clusters.

The cluster label is an “externalLabel” defined like this:

apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  labels:
    app.kubernetes.io/component: prometheus
    app.kubernetes.io/instance: k8s
    app.kubernetes.io/name: prometheus
    app.kubernetes.io/part-of: kube-prometheus
    app.kubernetes.io/version: 2.35.0
  name: k8s
  namespace: monitoring
spec:
  replicas: 2
  image: quay.io/prometheus/prometheus:v2.39.1
  thanos:
    baseImage: quay.io/thanos/thanos
    version: v0.28.1
    objectStorageConfig:
      key: thanos.yaml
      name: prometheus-thanos-objstore-config
  additionalScrapeConfigs:
    name: prometheus-additional-scrape-configs
    key: prometheus-additional.yaml
  alerting:
    alertmanagers:
    - apiVersion: v2
      name: alertmanager-main
      namespace: monitoring
      port: web
  enableFeatures: []
  externalLabels:
    cluster: qa-microservices-primary-us-west1

I’m not sure if Grafana Alerting does not support this or if I’m missing something here?
