I see <https://github.com/SigNoz/signoz/blob/main/deploy/docker/clickhouse-setup/otel-collector-config.yaml#L29|otlp/spanmetrics> as a receiver in the default otel agent setup. Is it expected to collect that info in the application prior to sampling?

I am using Ruby on Rails app now for my testing and I dont think they can do otel metrics as of now.
