What about this [1]?

> system.filesystem.free\_files  
> The number of free file nodes in the file system.

Looking at the code, it calls syscall STATFS, about which tutorialspoint [2] says:

> long f\_ffree; /\* total file nodes in file system \*/

In my understanding, on filesystems like EXT2/3/4 and XFS every file node consumes a single inode. And vice-versa, every inode represents a file node.
