Fields and codes in Apache FTP log

Where can I find information about the fields and codes in Apache's FTP logs?

I am curious about what the "189" here means and the "a _ o r" also.

Sun Jul 04 14:29:37 2010 0 xx.xxx.xx.xxx 189 /foo/bar/baz.php a _ o r foo@foo.c开发者_Go百科om ftp 1 * c

My google-foo failed me in locating this info.

Where can I read up on these codes?

Found it for you, seemed eerily familiar to wu-ftpd format: http://wu-ftpd.therockgarden.ca/man/xferlog.html

189 = filesize
a = ascii transfer
_ = no special action
0 = outgoing
r = authenticated user

Still don't believe it's Apache, but hey :P

I looked and failed too. But I can make an educated guess:

• the 189 looks like a file size, as seen in a directory.
• the a _ o looks like a set of Unix file permissions: All, Group, Other . That the Group permission is an underscore may mean that the file has no group permissions.
• the r? It could mean "read only". But I'm really guessing there.
