how auto-rotate atop logs
In RH/CentOS atop
is not being regulated by logrotate
.
In /usr/share/atop/atop.daily
there is an example script to deal with atop
log file rotation.
The script as a find line deleting logs older than 28 days as in:
# delete logfiles older than four weeks
# start a child shell that activates another child shell in
# the background to avoid a zombie
#
( (sleep 3; find $LOGPATH -name 'atop_*' -mtime +28 -exec rm {} \;)& )
You can copy that script to /etc/cron.daily
and change the number of days to 5.
( (sleep 3; find $LOGPATH -name 'atop_*' -mtime +5 -exec rm {} \;)& )
Dealing with daily files can also be a bit inconvenient. Using the above script, if you do not intend in doing a pure daily rotation, you can also edit /etc/sysconfig/atop
and change the duration, for instance for 10 minutes, as in:
INTERVAL=600
As an alternative, if you do want to keep rotating it daily, you can create a logrotate
file at /etc/logrotate.d/atop
as in:
/var/log/atop/atop_20[0-9][0-9][0-9][0-9][0-9][0-9] {
missingok
daily
nodateext
rotate 5
ifempty
nocreate
postrotate
/usr/bin/find /var/log/atop/ -maxdepth 1 -mount -name atop_20\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\[0-9\]\* -mtime +40 -exec /bin/rm {} \;
endscript
}
If you are doing the logrotate
version, you need to keep the daily files, and do not change the INTERVAL parameter.

we can see that atop logs are created on each day and that take a lot of space
ls -l /var/log/atop/ total 1634632 -rw-r--r-- 1 root root 127992086 Aug 30 01:49 atop_20180829 -rw-r--r-- 1 root root 262277153 Aug 31 00:00 atop_20180830 -rw-r--r-- 1 root root 321592670 Sep 1 00:00 atop_20180831 -rw-r--r-- 1 root root 330041977 Sep 2 00:00 atop_20180901 -rw-r--r-- 1 root root 269040388 Sep 3 00:00 atop_20180902 -rw-r--r-- 1 root root 274807097 Sep 4 00:00 atop_20180903 -rw-r--r-- 1 root root 85426960 Sep 4 06:03 atop_20180904 -rw-r--r-- 1 root root 0 Sep 4 06:03 daily.log
how to limit the atop log for example to only 5 logs ( 5 last days )

yael almost 6 yearsthis isnt logical , wht atop not include conf for this?
-
Ulrich Schwarz almost 6 yearsPlease provide
ls /etc/logrotate.d
. There might be a fileatop
in there which then governs how logrotate treats the log files.

yael almost 6 yearsregrading the second part , sorry but not understand to which value to change the INTERVAL=? , in order to keep the log for 5 days
