`mc support inspect` allows collecting files based on *path* from all backend drives. Matching files will be collected in a zip file with their respective host+drive+path. A MinIO host from October 2021 or later is required for full functionality. Syntax is `mc support inspect ALIAS/path/to/files`. This can for example be used to collect `xl.meta` from objects that are misbehaving. To collect `xl.meta` from a specific object, for example placed at `ALIAS/bucket/path/to/file.txt` append `/xl.meta`,...
