package OProfile is obsoleted https://src.fedoraproject.org/rpms/oprofile/blob/rawhide/f/dead.package but https://docs.fedoraproject.org/en-US/fedora/f33/system-administrators-guide/monitoring-and-automation/OProfile/ is alive.
Thanks for the info, I'll remove that chapter.
OProfile was apparently replaced by perf, and RHEL docs have a pretty thorough documentation on that (chapters 16 to 23 here: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/monitoring_and_managing_system_status_and_performance/getting-started-with-perf_monitoring-and-managing-system-status-and-performance), so I'll keep this issue open in case someone shows up and wants to convert it for Fedora.
