===Serilog existing log event levels===
*Log Levels used in taken from the Serilog doku : https://github.com/serilog/serilog/wiki/Configuration-Basics
{| class="wikitable sortable" | width = "50%"
|-
! LogLevel !! Purpose
|- align="left"
| Verbose || It is the noisiest level, generally used only as a last resort when debugging a difficult problem, and rarely (if ever) enabled for a production app. For example, local variables within an algorithm implementation might be logged at this level.
|- align="left"
| Debug || Debug is used for internal system events that are not necessarily observable from the outside, but useful when determining how something happened. For example, the details of requests and responses made to and from external integration points would often be logged at this level.

===Usage===Used to replace our existing Microsoft.Practices.EnterpriseLibrary.Logging with more up-to-date solution like Serilog.methods used in UBIKKernel===NewFeatures===*We replaced all the code that uses the Microsoft.Practices.EnterpriseLibrrary.Logging library with the Serilog library.

=== How To Configure Logging === *Added a way for the User to configure the default log path, the file count limit, the log event level and rolling policies through Logger.config with changing only the “value”“values”, which are set on their default.**The default Log path is set to the installation directory of UBIK. Its value can be changed to any local path (e.g. value="C:\Users\....logs").**Using OS Environment Variables (e.g.value="%SYSTEMDRIVE%\source\repos\UBIK.Server\Branches\..logs") is possible.**Using Relative path's (e.g.value="..\UBIKlogs" used for moving up in the hierarchy from the current directory) or (e.g.Studio\bin\Debug\Logs and its value can be changed to any local path(value="C:.\logs"represents the current directory itself)is possible.**The default for the event level is set to Debug and its value values can be changed to Verbose, Information, Warning, Error or Fatal.**File default count limit is set to 31 and the value its values can be changed to any positive number.**The default Rolling policies is set to Day and its values can be changed to "Day", "Month" or "Year". <source lang="xml"> <LoggingConfiguration> <add key="LogRootPath" value =""/> <!-- Values can be "Verbose", "Debug", "Information", "Warning", "Error", "Fatal". Normally "Debug" should be fine and you should only change if you know well what you do. --> <add key="LogLevel" value="Debug"/> <!-- The most recent 31 files are retained by default (i.e. one long month). If the value is empty the default will be applied. You must specifically set value="null" to remove this limit and all log files will be kept. You can set any other positive number --> <add key="RetainedFileCountLimit" value="31"/> <!-- Value can be either "Day", "Month" or "Year".Default is "Day"--> <add key="RollingInterval" value="Day"/></LoggingConfiguration> </source> === Since Version 3.6 ===Replace our existing Microsoft.Practices.EnterpriseLibrary.Logging with more up-to-date solution like Serilog.
