API call for file metadata

[richard5]

Hello, Basically what I need is an API call that I can use to:

- given a folder get as much information as possible about the folder and its files statistics, including sizes, how long they have been stored, how long they have been untouched and so on.

I know this is file level metadata that DFM SRM used to collect. Is there anything currently available in any NetApp API/SDK?

Thanks very much!

I'd also love to hear any comments such as "that doesn't exist natively but try this 3rd party tool"

In 7-mode, there is file-list-directory-iter-[start|next|end].  Here is the information that is returned:

Information about a single file.

Name	Range	Type	Description
accessed-timestamp	[0..2^32-1]	integer	Last asscess time of the file.  The value is in seconds since January 1, 1970.
acl-type		string	The type of access control list (acl) on the file. Possible values are: "no_acl", "nt_acl", "nfs_acl", and goddess forbid, "unknown".
bytes-used	[0..2^63-1]	integer optional	returns the number of bytes actually used on disk by this file
changed-timestamp	[0..2^32-1]	integer	Last changed time of the file.  The value is in seconds since January 1, 1970.
creation-timestamp	[0..2^32-1]	integer	Creation time of the file.  The value is in seconds since January 1, 1970.
file-size	[0..2^63-1]	integer	The size of the file in bytes.
file-type		string	Type of the file.  Possible values: file, directory, blockdev, chardev, symlink, socket, fifo, stream, lun. A cluster-mode volume can also return "junction".
group-id	[0..2^32-1]	integer	The integer id of the group owner of the file.
hard-links-count	[0..2^32-1]	integer	The number of hard links to the file.
inode-gen-number	[0..2^32-1]	integer optional	Inode generation number
inode-number	[0..2^32-1]	integer	The file node number.
is-empty		boolean optional	This element tells whether directory is empty or not. Directory is considered     empty if it only contains entries for "." and "..". This element is present if file is directory. In some special error cases like volume goes offline in between or directory is moved in the middle of getting this info, this field might not get set.
modified-timestamp	[0..2^32-1]	integer	Last modification time of the file.  The value is in seconds since January 1, 1970.
name		string	Name of the file.
owner-id	[0..2^32-1]	integer	The integer id of the owner of the file.
perm		string	File permission bits. It's similar to Unix style permission bits: 0755 gives read/write/execute permissions to owner and read/execute to group and other users. It consists of 4 octal digits derived by adding up bits 4, 2 and 1. Omitted digits are assumed to be zeros. First digit selects the set user ID(4), set group ID (2) and sticky (1) attributes. The second digit selects permission for the owner of the file: read (4), write (2) and execute (1); the third selects permissions for other users in the same group; the fourth for other users not in the group.

In clustered ONTAP, there is file-list-directory-iter.  It returns:

nformation about a single file.

creation-timestamp	[0..2^32-1]	integer	Creation time of the file.  The value is in seconds since January 1, 1970.
dsid	[0..2^64-1]	integer optional	Data Set ID
file-size	[0..2^63-1]	integer	The size of the file in bytes.
file-type		string	Type of the file.  Possible values: file, directory, blockdev, chardev, symlink, socket, fifo, stream, lun. A cluster-mode volume can also return "junction".

msid	[0..2^64-1]	integer optional	Mirror Set ID
name		string	Name of the file.
owner-id	[0..2^32-1]	integer	The integer id of the owner of the file.
perm		string	File permission bits. It's similar to Unix style permission bits: 0755 gives read/write/execute permissions to owner and read/execute to group and other users. It consists of 4 octal digits derived by adding up bits 4, 2 and 1. Omitted digits are assumed to be zeros. First digit selects the set user ID(4), set group ID (2) and sticky (1) attributes.
