Config.yaml - Linux/Docker all parameters

This is related only to a docker setup without redirecting logs to the file. In this case you do not need to search for a container-id and other useless things, just use docker logs instead.
But if you did redirect to the file, then you need to setup a logrotate

In the last case you would use something like

$ zcat /mnt/x/storagenode2/storagenode.log-20240501.gz | grep -E "used-space-filewalker" | tail

to find out when the used-space-filewalker have a last run (as an example).
