Found during testing for
https://github.com/grafana/mimir/issues/9072
Debug printout showed:
KRAJO: seriesName=cortex_request_duration_seconds_bucket,
metricFamily=cortex_request_duration_seconds_bucket,
type=GAUGE,
help=cortex_bucket_index_load_duration_seconds_sum,
unit=
which is nonsense.
I can imagine more cases where this is the case and makes actual sense.
Some targets might miss metadata and if there's a pipeline that loses it.
