Currently I have like 3.5GB of atop log files at
/var/log/atop/
I do not need that much log data.
Files there are as old as 28 days ago.
I cannot find a way to configure atop
log limit/quota/age.
How to lower that disk space usage?

Using this tip, I edited
/etc/init.d/atop
As the manual page says "four weeks", it was clearly there this command:
find $LOGPATH -name 'atop_*' -mtime +28 -exec rm {} \;
So, 28 days old files will be kept...
I changed it to
find $LOGPATH -name 'atop_*' -mtime +1 -exec rm {} \;
And ran this command:
sudo service atop _cron
Now the logs are only at most for yesterday, that is what I need.
Adding an answer for my version (also found in the man pages):
Ubuntu: 17.04
$ atop -V
Version: 2.2.6
The script is located: /usr/share/atop/atop.daily
I've dropped mine down to 7 days of logs.
38c38
< ( (sleep 3; find $LOGPATH -name 'atop_*' -mtime +28 -exec rm {} \;)& )
---
> ( (sleep 3; find $LOGPATH -name 'atop_*' -mtime +7 -exec rm {} \;)& )
Always read the man
page. Always.
Do so by running
man atop
If you would have done so, you would have seen this:
When atop is installed, the script atop.daily is stored in the /etc/atop directory.
This scripts takes care that atop is activated every day at midnight to
write compressed binary data to the file /var/log/atop/atop_YYYYMMDD
with an interval of 10 minutes. Furthermore the script removes all raw
files which are older than four weeks. The script is activated via the cron
daemon using the file /etc/cron.d/atop with the contents
0 0 * * * root /etc/atop/atop.daily
When the RPM `psacct` is installed, the process accounting is automatically
restarted via the logrotate mechanism. The file
/etc/logrotate.d/psaccs_atop takes care that atop is finished just before
the rotation of the process accounting file and the file
/etc/logrotate.d/psaccu_atop takes care that atop is restarted again after
the rotation. When the RPM `psacct' is not installed, these logrotate-files
have no effect.
This solution works for Ubuntu and perhaps other systems as well:
Open the config file /etc/default/atop
It will look something like this
# /etc/default/atop
# see man atoprc for more possibilities to configure atop execution
LOGOPTS="-R"
LOGINTERVAL=10
LOGGENERATIONS=28
LOGPATH=/var/log/atop
LOGGENERATIONS
is the number of days of history that will be stored (the config value is read by /usr/share/atop/atop.daily which will delete older log files)
You can change LOGGENERATIONS
to a smaller number of days.
All of the given answers were true at some point, although atop
seems to have changed the location of the config file multiple times. As @EEAA suggests, check man atop
for the config location of your specific version.
For me on atop v2.7.1, the config is located under /etc/default/atop
and provides all necessary info.
