logrotate hints

compress

compresscmd xz

compressoptions -9

---------------

compress manually:

--verbose show progress

To reduce system load:

/etc/cron.daily/logrotate from:

    /usr/sbin/logrotate /etc/logrotate.conf

to:

    nice -n 19 ionice -c3 /usr/sbin/logrotate /etc/logrotate.conf

-M xz option sets memory limit, please check man, for example 32M is required for -3 compression option, for example :

compressoptions -3 -M 128M

also cpulimit may be useful:

cpulimit -l 20

sets cpu usage to 20%

for example:

cpulimit -l 20 nice -n 19 ionice -c3 /usr/sbin/logrotate /etc/logrotate.conf
