[Orca-users] Re: Updating Orca graphs at longer intervals

[Blair Zajac]

If rsync is touching the files on the Orca server, then it's possible
that Orca is rereading old files.  Orca will compare the file's inode,
device the file's on, the files' size and mtime.  If any of these
have changed, then Orca will reread it.

Blair
