Understanding CPU utilization in the Posit Workbench Admin Dashboard

Question: Why does the admin dashboard show different CPU utilization than what is displayed in the sessions tab?

Answer: The sessions tab in the admin dashboard filters out the child processes of forked R sessions. Whenever a user does parallel processing or forks an R session, it creates a child process. These child processes show up when you execute a grep command or run rstudio-server active-sessions. However, while these child sessions do not show up on the admin dashboard to reduce clutter, the user sessions are real-time.
