IO error reading /etc/rstudio/rserver.conf: unrecognised option 'audit-r-console'



I am trying to add auditing and logging of rstudio console commands in my rstudio server that is installed on an Ubuntu machine. But whatever I add in the /etc/rstudio/rserver.conf file (I tried two different settings) and then restart the server by sudo rstudio-server restart the following error is thrown,

IO error reading /etc/rstudio/rserver.conf: unrecognised option 'audit-r-console'

Finding out my rstudio server version on my ubuntu

R console auditing is a feature of RStudio Server Pro, and is not available in the open-source version of RStudio Server. Do you have the professional version of RStudio Server installed?


It's not the professional version.
I find this confusing, because all your documentation paragraphs are common for pro and normal versions but some apply to just pro. How do we find that this is for pro only while that applies for both?
