Pokesensor vs smartmontools

Pokesensor is a local hardware-monitoring app for Windows, macOS, and Linux. It shows live CPU, GPU, memory, and disk readings, with one-second sensor graphs and an always-on-top mini overlay. Desktop alerts can notify users when readings move outside a configured range, and session logs export to CSV or JSON. The free plan includes live monitoring, the overlay, alerts, and support for all three platforms. Graphs can show a configurable history window up to 24 hours; VIP++ adds 30-day logging, while VIP Super+ includes unlimited logging history. The app runs without cloud services, accounts, telemetry, or sending hardware data. Its default polling interval uses well under 1% CPU, and its install footprint is 18 MB. Monthly plans are VIP at $5.00 USD, VIP+ at $10.00 USD, VIP++ at $20.00 USD, and VIP Super+ at $30.00 USD. Fan control depends on what the motherboard and operating system expose.

smartmontools is a free package containing smartctl and smartd for controlling and monitoring storage devices through SMART. It supports ATA/SATA, SCSI/SAS, and NVMe disks, as well as SCSI/SAS tape devices. smartctl can report SMART health status, show capabilities such as error logging and offline surface scanning, display vendor-specific attributes, start device self-tests, and read their logs. A failing health status can mean a device has failed or predicts failure within 24 hours. smartd periodically monitors SMART status, error and self-test logs, and attribute changes; it can schedule tests and report errors and attribute changes to syslog. It also supports warning emails and executable commands. The project says it should run on modern Linux, BSD variants, macOS, Solaris, Windows, Cygwin, OS/2, eComStation, and QNX systems, and can run from various Live CDs and DVDs. The package uses the GNU GPL Version 2 license and was originally derived from the Linux smartsuite package. Its capabilities focus on SMART health reporting, testing, and ongoing monitoring.
