Otel-collector Monitoring

[cmergenthaler]

My otel-collector instances do not provide the two metrics otelcol_processor_dropped_spans and otelcol_processor_dropped_metric_points for critical monitoring as described in docs.
Do they need to be enabled somehow? I am using prometheusremotewrite, otlp and instana exporters. Following is an example of the metrics being exported:

Hi guys, is there anything manually we have to do to enable emitting these metrics?
In my case, i cannot see otelcol_exporter_send_failed_metric_points
