Hello,

I’m facing an issue where I can’t properly save a metric;  
Inside a k8s cluster I have a rule inside a `servicemonitor.yaml` file that drops any metric coming from namespaces that match a specific regex, something like:

```auto
    - sourceLabels: [namespace]
      regex: z{3,6}
      action: drop

```

this works, but now I have to implement a way to save a single metric, specifically `kube_namespace_created` before dropping all the others, only for those namespace that match the regex.

Can someone give me an heads up? Thanks
