I have an app.r running on a Shiny Server.

I've added this code to write to the log file, as answered at https://stackoverflow.com/a/54778579/10276092

cat(file=stderr(), paste0("\nStarting application: ", Sys.time(), "\n"))

This code is placed at the top of the UI code (for initialization), as well as in the middle of the UI display code.

However, the code only writes to the log file in /var/log/shiny-server/[appname]-shiny-[date]-[time]-[stamp].log when the R Shiny server re-initializes the app, like after editing app.r.

Is there a way to log every time the Shiny Page is opened by different users?

Try placing that code in your `server()` function rather than as a global statement. – MrFlick Jun 17 '21 at 18:06
Thank you! This is what I needed to do. – M.Viking Jun 17 '21 at 18:16
