Deprecate SCREEN_LOGDIR in favor of LOGDIR
This is the first step in the log file cleanup. If SCREEN_LOGDIR is still set, symlinks will be created in the old screen log directory so things like the devstack-gate log collector continues to work. bp:logging-and-service-names Change-Id: I3ac796e322a18dbd0b8b2310a08310ca159d7613

Logging the Screen Output

Logging the Service Output
|
||||
--------------------------
|
||||
|
||||
| *Default: ``SCREEN_LOGDIR=""``*
|
||||
| By default DevStack runs the OpenStack services using ``screen``
|
||||
which is useful for watching log and debug output. However, in
|
||||
automated testing the interactive ``screen`` sessions may not be
|
||||
available after the fact; setting ``SCREEN_LOGDIR`` enables logging
|
||||
of the ``screen`` sessions in the specified directory. There will be
|
||||
one file per ``screen`` session named for the session name and a
|
||||
timestamp.
|
||||
| *Default: ``LOGDIR=""``*
|
||||
| DevStack will log the stdout output of the services it starts.
|
||||
When using ``screen`` this logs the output in the screen windows
|
||||
to a file. Without ``screen`` this simply redirects stdout of
|
||||
the service process to a file in ``LOGDIR``.

||||
*Note the use of ``DEST`` to locate the main install directory; this
|
||||
is why we suggest setting it in ``local.conf``.*
