We recently added a sample_tags column. If the integration is providing tags by default , please add them in this column. See https://docs.datadoghq.com/developers/integrations/check_references/#metrics-metadata-file.

@dd-dominic I don't know offhand if the integration is providing these tags. Since it's listed as an optional attribute in the documentation, could we add that info in a followup PR? I'd love to get these storage metrics documented and then do more of the metadata/housekeeping stuff separately if that's possible. Please let me know what you think!
