Hi @timansky,

Thank you for the issue. We do not support label_format at this time. It is on the roadmap as a lower priority (not much used) feature.

What is your use case?

For example we have different label name, but with same values. Unfortunately we can not convert label name because of nested level of log capturing. For example nginx logs inside kubernetes log (writing different exporter for each pod is to complicated)

|~ (?i)"level(_name)?":"(error|warn|warning|notice|critical|alert|emergency|panic|fatal)"
