Log Rotation

Plesk rotates logs using the logrotate utility. This is located in
the $PRODUCT_ROOT_D/logrotate/sbin/logrotate directory, where the
$PRODUCT_ROOT_D is /usr/local/psa for RPM-based systems or
/opt/psa on DEB-based systems.

You can set the following parameters of logs rotation:

• Log rotation condition. This may be one of the following:
  • Size - Plesk rotates logs when their size exceeds a particular
    limit.
  • Time - daily, weekly, or monthly logs rotation.
• Maximum number of log files.
• Log compression. Enable this, if you want Plesk to compress log files
  to gzip archives.
• Email to which Plesk should send processed log files.

Log Rotation Settings of Plesk Services

You can define log rotation parameters for Plesk services in general and
for each domain separately.

Log rotation parameters for Plesk services are defined in the
$PRODUCT_ROOT_D/etc/logrotate.conf configuration file. Part of this
file is shown below.

# less /usr/local/psa/etc/logrotate.conf
include /usr/local/psa/etc/logrotate.d
/usr/local/psa/var/log/xferlog.processed {
    missingok
    rotate 3
    size    10M
    compress
    nocreate
}

Log Rotation Settings of Hosted Domains

In turn, log rotation parameters for domains hosted on the Plesk server
are stored in configuration files in the
$PRODUCT_ROOT_D/etc/logrotate.d/ directory.

You can configure log rotation for a particular domain through the Plesk
GUI. To do this:

1. Log in to Plesk and go to the subscription.
2. In Website & Domains, click Logs under the domain for which
   you want to change log rotation settings.
3. Click the icon on the top right and click Manage
   Log Files.
4. Click Log Rotation.
5. Change the log rotation configuration if needed.

When you click OK, the configuration is saved in the domain
logrotate configuration file
$PRODUCT_ROOT_D/etc/logrotate.d/< domain_name >. A
fragment of this file is provided below. Configuration changes are
applied equally for all log files of this domain.

/var/www/vhosts/domain.tst/statistics/logs/*.processed {
    monthly
    rotate    10
    compress
    missingok
}

Adding Creation Date to Rotated Log File Names

To make working with log files more convenient, you can include the file
creation date into the names of rotated log files. If you do this, the
names of rotated log files will have the following format
<log_name> .processed-YYYYMMDD.gz, where <log_name> is the
name of the log file before rotation, like error_log or
httpsd_access_log, and YYYYMMDD is the date of the log rotation.
For example, error_log.processed-20130101.gz.

To include the creation date into the names of rotated log files, open
the desired log rotation configuration file and add the line dateext
to the corresponding sections.
