__meta_kubernetes_namespace="prometheus-dev"

__meta_kubernetes_pod_container_port_number="9095"

many thanks for help

Hi,

It sounds like you want a relabeling rule like:

relabel_configs:

- action: replace

  source_labels: [__meta_kubernetes_pod_container_name, __meta_kubernetes_namespace, __meta_kubernetes_pod_container_port_number]

  target_label: instance

  regex: (.+);(.+);(\d+)

  replacement: $1.$2:$3

(The source labels are concatenated with a ";" by default for the regex match - you can control this character by setting "separator: ..." explicitly in the relabeling rule)

Be aware that the combination of pod container name, namespace, and port number doesn't necessarily give you a unique instance identifier, as there could be multiple pods with the same attributes. If you have multiple pods of the same type, you probably want some distinguishing label like "__meta_kubernetes_pod_name" or so in there. Most commonly, the labels that identify a type of instance rather than a single specific instance / pod, are put into the "job" label instead (with sometimes some dimensions like namespace etc. broken out into separate labels as well).

hi thanks it works!!!

there is the possibility to mantain other label without using to match the target? only to filter in grafana?

thanks
