HOWTO :: Enable ATOP logging

You first need to emerge atop if not already installed to enable atop logging. 

/usr/bin/emerge -av atop

Then modify 

nano /usr/share/atop/atop.daily

And configure your interval (default 600). Setting it to 60 will tell atop to run every 1 minute and save the output into /var/log/atop/atop_XXXXXXX

You can then read this file using

atop -r /var/log/atop/atop_XXXXXXXX

Navigate through the time using t (for forward) and T (for back). 

Or you can use b to enter the time. 

Log reader also allows you to modify the output like in atop

a – sort in order of most active resource.

c – revert to sorting by CPU consumption (default).

d – sort in order of disk activity.

m – sort in order of memory usage

n – sort in order of network activity

For the new Artix environment, you need to do the following,

pacman -Sy

pacman -S atop

nano /etc/default/atop

make sure that the file looks like below,

## default options
#LOGOPTS=""
## default interval in seconds
LOGINTERVAL=60
## default number of days
LOGGENERATIONS=28
## log location
LOGPATH="/var/log/atop"
