Prefail monitors disk S.M.A.R.T. health across server fleets and sends warnings about problems and possible next steps. Its SENTINEL system weighs more than 25 S.M.A.R.T. attributes to assign each disk a risk score from 0 to 100, with history views showing seven-day changes and whether signals are stable or rising. Alerts include severity, an explanation, and a recommended action, and can be acknowledged, muted, or dismissed in batches. Supported RAID setups include MegaRAID 9260/9361/9460, Adaptec SmartRAID, and Linux mdadm, with visibility into disks behind controllers. Prefail offers Telegram alerts and a Telegram Mini App dashboard, with email as a fallback, plus a weekly PDF fleet report. Its Linux agent is a Bash script that runs smartctl and transmits S.M.A.R.T. output. Prefail says it sends data over TLS and stores it on a dedicated European server. The free tier covers up to two servers; paid plans start at $9/mo. The maker warns that S.M.A.R.T. monitoring cannot catch sudden failures and does not replace backups.
