What this PR does / why we need it:
By default, we use the
filenameandhostlabels to determine if a stream is lagging when pushing from Promtail to Loki. This PR introduces the ability to customise this list with a comma-delimited set of labels.We need this because sometimes the
filenamelabel is not available (perhaps it was dropped in a relabel config), and we need to use another label for this purpose.Which issue(s) this PR fixes:
N/A
