For users that have access to the ``data/Settings`` model or ``view/DataSettings``,
the global levels of logging can be managed. 

This level will affect the Log block of messages at the
bottom of a selected transaction on the Transaction interface and
does not for example affect the transaction or sub transaction Action and 
Detail information.

Log levels are *cumulative*, in other words, more detailed levels include
all details from less detailed levels. The levels includes messages and
have severity values as follows:

========  ==========================================================  ========
Level     Description                                                 Severity 
========  ==========================================================  ========
Disabled  disables all transaction log messages                       999
Error     only displays error messages                                40
Warning   also adds warning messages to above                         30
Info      also adds informational messages to above                   20
Verbose   also adds messages used for diagnostic purposes to above    15
Debug     also adds advanced diagnostic messages - for future use     10
========  ==========================================================  ========

* The Severity values are referenced (from value - to value) in transaction details
  when the log level is changed on this setting or changed by lower level
  administrators from the **System Settings** menu. See: :ref:`manage-system-settings`.
* If a transaction fails, the Log block will include all entries with severity
  values larger than that of the default or selected level of logging.
* The log levels of data syncs can be set to override these global levels. 

  The transaction log level used for data sync and its immediate sub-transactions is by default
  set to Warning when it is not set.
