The customer can see these errors in different dashboards in the console:


Danger alert:An error occurred
found duplicate series for the match group {namespace="some-namespace", pod="pod-name-6fdcdb79bb-88zjp"} on the right hand-side of the operation: [{__name__="namespace_workload_pod:kube_pod_owner:relabel", namespace="some-namespace", pod="pod-name-6fdcdb79bb-88zjp", workload="pod-name", workload_type="deployment"}, {__name__="namespace_workload_pod:kube_pod_owner:relabel", namespace="some-namespace", pod="pod-name-6fdcdb79bb-88zjp", prometheus="openshift-monitoring/k8s", workload="pod-name", workload_type="deployment"}];many-to-many matching not allowed: matching labels must be unique on one side

So, what we see is that there are two series one including the label

                prometheus="openshift-monitoring/k8s"

And not the other.

the customer has tried this exact query:

namespace_workload_pod:kube_pod_owner:relabel{namespace="some-namespace", pod="pod-name-6fdcdb79bb-88zjp", workload="pod-name", workload_type="deployment"}

And we see exactly two lines.
