For reading the Denodo Server logs, I would use the [Log Custom Wrapper](https://community.denodo.com/docs/html/document/denodoconnects/6.0/Denodo%20Log%20Custom%20Wrapper%20-%20User%20Manual) available under **"Downloads > Denodo Connects"** section of the Support Site because this Custom Wrapper has better performance than the DF wrapper and it can search the entries by date.
Also, each log file includes different information for each tuple so for reading log files other than **vdp.log**, I would change the [patterns](https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html) of the Log Custom Wrapper.
You could refer to [Reading the VDP logs with Denodo Log Custom Wrapper](https://community.denodo.com/kb/view/document/Reading%20the%20VDP%20logs%20with%20Denodo%20Log%20Custom%20Wrapper?category=Custom+Elements) Knowledge Base article for more information.
To compare the configuration of different environments, I would create the ConfigurationParameters.properties file as a [Delimited File](https://community.denodo.com/docs/html/browse/6.0/vdp/administration/creating_views/importing_data_sources_and_creating_base_views/delimited_file_sources) datasource using the tuple pattern that matches the contents of the file like:
Then, I would compare the views(Configuration files) obtained from different environments by performing operations like join or minus in the Virtual DataPort Administration Tool.
Hope this helps!
