Pokesensor vs Prometheus Node Exporter

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.

Prometheus Node Exporter exposes hardware and operating-system metrics from *NIX kernels for Prometheus. Written in Go, it uses pluggable collectors, with default coverage for CPU, disk I/O, filesystem, memory, and network metrics where the operating system supports them. Command-line flags enable or disable collectors, and some collectors accept include or exclude filters. The exporter listens on HTTP port 9100 by default. Documentation covers Linux distribution packages, an Ansible community role, and container deployment. Containerized monitoring requires host namespace access and suitable mounts; some systems also need an extra capability for the timex collector. Certain collectors are off by default because they can have high cardinality, take longer, or consume host resources. The project is Apache 2 licensed and free, with no paid plans listed. Windows users are directed to Windows Exporter.
