btmp logs failed logins and grows forever on internet-facing servers. Set up logrotate to keep it under control before your disk fills up.

Your logs are in journald, not /var/log. journalctl queries that work, awk patterns that hold up, and five popular one-liners that quietly return nothing.

Service restart not showing logs? systemd hides stdout. Learn journalctl, systemctl status, and debugging workflows for silent systemd failures.

logrotate keeps your /var/log from eating the disk, configure rotation schedules, compression, and retention for any service log.
