If you need to provide any headers such as authentication details in order to utilise your OTEL collector you can add them into the `OTEL_EXPORTER_OTLP_HEADERS` environment variable. The frequency at which the metrics are exported can be configured by setting `OTEL_METRIC_EXPORT_INTERVAL` to the number of seconds you require between each export interval (`30` by default).

Please note that using `OTEL_EXPORTER_OTLP_PROTOCOL` will alows you to set it up to `grpc` to conect to otel collector. Also `OTEL_EXPORTER_OTLP_ENDPOINT` should be set to the right enpoint (eg: http://opentelemetry-collector.open-telemetry-system:4317)
