Over time, the Vaultwarden log file can grow to a significant size. Using logrotate, we can periodically rotate logs.

sudo nano /etc/logrotate.d/bitwarden

/var/log/bitwarden/*.log {
    # Perform logrotation as the bitwarden user and group
    su bitwarden bitwarden
    # Rotate daily
    daily
    # Rotate when the size is bigger than 5MB
    size 5M
    # Compress old log files
    compress
    # Keep 4 rotations of log files before removing or mailing to the address specified in a mail directive
    rotate 4
    # Truncate the original log file in place after creating a copy
    copytruncate
    # Don't panic if not found
    missingok
    # Don't rotate log if file is empty
    notifempty
    # Add date instead of number to rotated log file
    dateext
    # Date format of dateext
    dateformat -%Y-%m-%d-%s
}

To view a compressed log file without manually decompressing:

zcat logfile.gz
zless logfile.gz
zgrep -i keyword_search logfile.gz
