Change atop log interval from 10 minutes to 1 minute

On recent versions the configuration file used by systemd is /usr/share/atop/atop.daily (see /etc/systemd/system/multi-user.target.wants/atop.service).

Here you can change the variable INTERVAL and restart the atop service.

Add the following line to /etc/atoprc, if the file doesn't exist create it:

interval 60

atop no longer uses the /etc/default/atop file.

Unless you are using an older version of atop. Then you might want to change INTERVAL=600 to INTERVAL=60 in /etc/default/atop.

Try to edit the file /usr/share/atop/atop.daily and change INTERVAL=.

Then:

service atop restart
