In their own words
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.
Sidebar Diagnostics
Sidebar Diagnostics is a free Windows desktop sidebar for viewing hardware diagnostic information. It monitors CPU, RAM, GPU, network, and logical drives, and can graph those measurements. The sidebar can show a clock and supports alerts, hotkeys, and monitors with different DPI settings. The project describes extensive customization, with hardware data supplied by Libre Hardware Monitor. The README lists Windows 7, Windows 8, Windows 8.1, and Windows 10 as supported systems. Releases include an installer and a standalone ZIP; the standalone build does not update automatically. The application must be run as administrator. The GitHub repository identifies it as GPL-3.0 software and provides an issue template for reporting problems. The author says it will always be free on GitHub and invites donations. The Free plan costs nothing. Remote monitoring is not supported.
