ELX-HealthMonitor vs NEAITECH DiskHealth

ELX-HealthMonitor is a free web tool for viewing current Linux server activity and historical readings. It reads data directly from /proc, /sys and smartctl, without a separate collector or time-series database. Metrics cover processor, memory, disks, filesystems, network, temperature and processes. SMART details include drive health, temperature, power-on hours, reallocated and pending sectors, SSD wear and lifetime writes. RAID views show array state, members, failed disks, resync progress, mirror consistency and the last check's mismatch count. For systemd units, the interface reports processor, memory, disk I/O, task count and restarts, and lets users start or stop units or change boot behavior. Alert rules support hold-down periods and email through SMTPS, STARTTLS or plain SMTP. History retains three days of raw readings by default, then five-minute average, minimum and maximum buckets; data is deleted after a month by default. Supported systems are Debian and Ubuntu with systemd on amd64, arm64 and armhf. The web interface uses port 8555 by default. smartmontools is recommended and required for SMART data. Settings and history stay local, with no analytics or crash reporting.

NEAITECH DiskHealth shows disk and volume capacity, free space, health signals, and SMART information when available. It lists support for HDD, SSD, and NVMe drives, and is described as an observation tool that does not modify disks. Users can review drive and volume status, available space, and SMART notes; the maker recommends backup or cloning if status is FAILED or space is low. SMART availability and results depend on the operating system and smartctl. The free edition is described as local and offline, with no content telemetry; logs and reports are saved only where the user chooses. Downloads include Windows and macOS installers with Python and full or lightweight Linux setup options. DiskHealth is available for Windows, macOS, and Linux. The Free plan costs nothing. Pro for one OS costs €49, paid once, with updates for one year; Suite Utility costs €129, paid once, and Enterprise costs €249, paid once. Remote monitoring is not available.
