In general, to read the Denodo server logs, you could use the Log Custom Wrapper. In order to extract information from log files(eg. vdp-dmt.log), you could specify sample values for Data pattern, Date extractor pattern, etc provided in the Knowledge Base article [Reading the VDP logs with Denodo Log Custom Wrapper](https://community.denodo.com/kb/en/view/document/Reading%20the%20VDP%20logs%20with%20Denodo%20Log%20Custom%20Wrapper).
Also, you can find and use the vdp-dmt.log file under the directory <DENODO_HOME>\logs\vdp-dmt for Filepath while creating the base view.
Hope this helps!
