try on your machine

The command "atop -d" is used to start the atop utility in daemon mode, which means it runs in the background and continuously monitors system resource utilization.

Here's a breakdown of the command and its options:

"atop": This is the command itself, used to start the atop utility.
"-d": This option stands for "daemon" mode, indicating that atop should run as a background process and regularly collect and report system performance data.

When you execute this command, atop will start monitoring the system resource usage at specific intervals (default is 10 seconds) and keep updating its records. It provides a comprehensive view of system performance, such as CPU usage, memory utilization, disk activity, network usage, and process-level details.

You can exit atop by pressing "q" or terminating the command. By default, atop stores the collected data in log files located in "/var/log/atop". You can use other command options to customize the behavior and output format of atop.
