In their own words
HWMonitor
HWMonitor reads PC system-health sensors, including temperatures, voltages, power, current, fan speed, utilization, and clock speeds. It covers CPUs and GPUs, supported LPCIO chips, memory modules with thermal sensors, S.M.A.R.T. storage devices, and batteries. The listed Windows release is version 1.68 for x86/x64, available as an installer or ZIP download, and CPUID lists a separate Windows ARM64 download. Version 1.68 adds PCI Express error counters for AMD and Intel GPUs, NPU and platform metrics, HDD IOPS and average latency, and saved device and sensor tree state. CSV logging is listed as a feature. The free HWMonitor plan monitors PC hardware sensors on Windows x86/x64. HWMonitor PRO adds remote monitoring over TCP/IP, saved monitoring data, and bitmap logging graphs. Its Android app reports device temperatures and battery details, plus CPU clock and utilization and, on supported devices, GPU clock. Android remote connections require local Wi-Fi, and the app can monitor up to 10 Windows PCs or Android devices.
Nagios XI
Nagios XI monitors servers, network devices, applications and services from a Linux server you manage. It checks configured thresholds, records results and sends notifications. Standard includes more than 90 configuration wizards, auto-discovery, dashboards, performance graphs, an open REST API, automation, configuration rollback and snapshots. Enterprise adds SLA and capacity-planning reports, scheduled reports and pages, business process intelligence, bulk changes and an audit log. Users can be restricted to assigned host and service groups, with authentication options including Active Directory or LDAP over SSL, Microsoft Entra ID single sign-on and Duo two-factor authentication. It is self-hosted on Linux, with virtual machine images for several hypervisors and offline installation on Red Hat and CentOS Stream. A 30-day trial provides unlimited monitoring, Enterprise features and direct support without a credit card. The free plan is limited to 7 nodes or 100 services, whichever comes first. Paid perpetual licenses are priced by monitored nodes: Standard is $2,595.00 once and Enterprise is $4,690.00 once, each shown for 100 nodes.
