All the logs are rotated by means of the preinstalled and adjusted logrotate. By default, the previous 10 days of logs are stored, but it is possible to enlarge this period by means of changing the corresponding configuration file in the directory /etc/logrotate.d/ (replace rotate 10 with the value you need). For instance, for Wialon Local logs that is /etc/logrotate.d/wlocal. After you have changed the file, update the configuration using the command logrotate -f -v /etc/logrotate.d/$filename$, where $filename$ is the name of the file you have changed.
