# Add datetime to rotated filename
    # Note: CentOS 7 logrotate doesn't support %H%M%S, using %s (unix timestamp) for uniqueness

# Don't error if log file is missing

# Don't rotate empty files
    notifempty

# Copy and truncate instead of moving the log file
    # This allows the service to keep writing without restart
    copytruncate

# Compress rotated files with gzip.
    # I would prefer to use zst when it is available,
    # but this requires conditional compression and postrotate
    # script, what makes config more complex.
