What does the double asterisk(**) mean in the path?

There's two meaning of wildcards in paths for file collections.

• * is a simple, non-recursive wildcard representing zero or more characters which you can use for paths and file names.
• ** is a recursive wildcard which can only be used with paths, not file names.

For examples,

• /var/log/** will match all files in /var/log and all files in all child directories, recursively.
• /var/log/**/*.log will match all files whose names end in .log in /var/log and all files in all child directories, recursively.
• /home/*/.bashrc will match all .bashrc files in all user's home directories.
• /home/*/.ssh/**/*.key will match all files ending in .key in all user's .ssh directories in all user's home directories.

Oh, I see. It doesn't seem to be supported by sumologic.
(I'll also fix the text. Thank you for your correction.)

As you said in the above case, I think we should consider reducing the dynamic depth on the structure level or distributing the collector to the per dynamic depth.
This way could also reduces the searching load, so I think it would be better to consider it as an alternative.
