Which command is used to display the current tuning profile?

The command that correctly displays the current tuning profile is tuned-adm profile_info. This command specifically provides information about the currently applied tuning profile in the system, showing how the system’s performance settings are configured based on the selected profile.

This is beneficial for users who need to verify their active tuning settings and ensure that the system's performance is optimized for its current workload. Understanding the active profile helps in troubleshooting and performance monitoring, enabling administrators to make informed decisions about any necessary adjustments to the system’s configuration.

Other commands listed do not directly provide this specific information about the current tuning profile. For example, tuned-adm status delivers an overview of the tuning daemon's operational state, while systemctl status tuned is used for checking the status of the tuned service itself, rather than the profile in use. The tuned-adm list command shows all available tuning profiles but does not indicate which one is currently active.
