Looks to be a bug, garbage_collection_pieces_count and garbage_collection_pieces_skipped are swapped when lazy file walker is used (default).
This should fix the problem:

Until that, you can check the value of ..._skipped
Not: it’s still not very useful metrics, as the value is updated after any execution. If two satellites have totally different values, the first one may not be visible, only by max/min fields.
I am considering to add the satellite as tags to all of these metrics…
