logrotate

[Source]

The logrotate command closes and reopens the log file. This is intended to help with log rotation on Linux file systems.

Most Linux systems come preinstalled with a logrotate program, which is separate from this command. Application specific log rotation scripts are placed in /etc/logrotate.d

The following script is a sample that can be created as /etc/logrotate.d/rippled

/var/log/rippled/*.log {
  daily
  minsize 200M
  rotate 7
  nocreate
  missingok
  notifempty
  compress
  compresscmd /usr/bin/nice
  compressoptions -n19 ionice -c3 gzip
  compressext .gz
  postrotate
    /opt/ripple/bin/rippled --conf /opt/ripple/etc/rippled.cfg logrotate
  endscript
}

You can configure parameters such as minsize and rotate depending on the amount of logs you keep. Use the log_level setting in your rippled.cfg file to configure how verbose your server's logs are. This sample script is based on standard log_level and will store approximately 2 weeks worth of logs in a compressed format.

Note: You should have only one system logrotate script per application. Please ensure that you do not have any other log rotation that handles the same directory.

The logrotate method is an admin method that cannot be run by unprivileged users.
