Package Logging
***************

Description
===========

Logging use the module **log.py** of the logging package **ut_log**.
The module supports two Logging types:

#. **Standard Logging** (std) or 
#. **User Logging** (usr).

The Logging type can be defined by one of the values 'std' or 'usr' of the parameter log_type; 'std' is the default.
The different Logging types are configured by one of the following configuration files:

#. **log.std.yml** or 
#. **log.usr.yml** 
  
The configuration files can be stored in different configuration directories (ordered by increased priority):

#. <package directory of the log package **ut_log**>/**cfg**,
#. <package directory of the application package **ui_eviq_srr**>/**cfg**,
#. <application directory of the application **eviq**>/**cfg**,

Log message types
=================

Logging defines log file path names for the following log message types: .

#. *debug*
#. *info*
#. *warning*
#. *error*
#. *critical*

Log types and Log directories
-----------------------------

Single or multiple Application log directories can be used for each message type:
