• Supports configuring sampleRate to limit the number of reported logs when --experimental.otlpLogs=true is enabled.
• Currently, Traefik supports sending access logs to an OTLP backend, but it does not support limiting the volume of logs sent via a sampleRate attribute—unlike the mechanism used for traces. This means that access logs are reported unconditionally for every single request, which is not always the behavior I desire.
