Steps to reproduce:
- Configure Kubernetes monitoring.
- Wait for collects;
- Create a pod with same name in different namespaces.
Result:
The Kubernetes cluster state by HTTP template, in the "Pod discovery" LLD rule, all preprocessing rules of the Prometheus Pattern type filter only by POD name. If there is a pod with the same name in different namespaces, the filter does not work correctly.
Expected:
Change preprocessing rules, include namespace filters.
