I think this is more of a missing Kubernetes feature than a prometheus-operator related one. StatefulSets don't yet fully support expanding volumes. Related enhancement proposal: https://github.com/kubernetes/enhancements/pull/660

Hi @ecojan, thanks for your work on this very useful feature. Do you think that you'll have the opportunity to come back to this PR in the future?

I think this is more about that plugins.inputs.events.in is not an existing metric in the pipeline stats, only plugins.inputs.events.out: https://www.elastic.co/guide/en/logstash/current/node-stats-api.html#pipeline-stats So having this metric populated doesn't make sense: https://github.com/BonnierNews/logstash_exporter/blob/d0391964df9c3ba49a605c0c7d98399b0e54e586/collector/nodestats_collector.go#L539-L547
