Hi,
When connecting Denodo from client application like Power BI and Excel via ODBC, you can store all the requests received by the ODBC DSN by enabling the options 'CommLog (C:\denodoODBC_xxx.log)' and 'MyLog (C:\mylog_xxx.log)' available in the advanced options dialog of the DSN configuration. This only applies to a windows environment, refer to the section [Set Up a DSN on Windows]( https://community.denodo.com/docs/html/browse/7.0/vdp/developer/access_through_odbc/configuration_of_the_odbc_driver_on_windows/configuration_of_the_odbc_driver_on_windows#set-up-a-dsn-on-windows) for more information.
In case of Linux environment, configure *Commlog=1;Debug=1* in the DSN template file, you could refer to the section [Register a Data Source (DSN) on UnixODBC]( https://community.denodo.com/docs/html/browse/7.0/vdp/developer/access_through_odbc/configuration_of_the_odbc_driver_in_linux_and_other_unix/configuration_of_the_odbc_driver_in_linux_and_other_unix#register-a-data-source-dsn-on-unixodbc) for more details on it.
Hope this helps!
