Also, from CloudWatch how can analyze the FSx for lustre access / file management logs also.

Answer

You can check the metadata of files within the directory where your **Amazon FSx file system** is mounted using the ```stat /mnt/fsx/filename``` command. This command will provide detailed information about the file, including:

```
  File: example.txt
  Size: 1420            Blocks: 8          IO Block: 4096   regular file
Device: ca01h/51713d    Inode: 1087894     Links: 1
