Thank you for that. Now you mention it, I do vaguely remember having been bitten by that before.
It might be worth a note in the documentation at https://prometheus.io/docs/prometheus/latest/configuration/configuration/#metric_relabel_configs where it says "It has the same configuration format and actions as target relabeling" At https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config it then says: Labels starting with __ will be removed from the label set after target relabeling is completed. which is true, but on first reading I hadn't twigged that this applies only to *target* relabeling.
