openssh unix dev - Dec 2013 - To see fullpath instead of realitive path in chrooted sftp

Hi
In a chrooted sftp syatem i'm trying to log (user file transaction log) 
full path instead of relative path. (like /home/user1/file/a.txt instead of
/file/a.txt). Without chroot sftp it works fine, but in chrooted
system i do not get full path, which i need badly. Goggled for it for so long,
but no luck. Is there any way? any hint from you will be
appreciated.

Thnaks
