I put `piecestore` on FATAL, because it logs the lost races too on ERROR or WARN levels.

```auto
time ERROR piecestore upload failed ....

```

What does `collector` do? It’s the Garbage Collector that we are debugging? Or it’s another walker?  
If I put it on ERROR, does it logs the GC start and finish?

```auto
time INFO collector deleted expired piece {"Process": "storagenode", "Satellite ID": "xxx", "Piece ID": "xxx"}

```

Does this looks OK, after container name?

```auto
--log.level=info \
--log.custom-level=piecestore=FATAL,collector=ERROR \

```
