Our verdict on Xymon
Xymon is an open-source, self-hosted monitoring system for servers, applications, and networks. It is designed primarily for Unix-like environments, including Linux, FreeBSD, OpenBSD, Solaris, macOS, and other Unix-like systems. Its monitoring model combines network-service tests with client-reported host data, making it a fit for teams that want classic service and status monitoring across infrastructure they operate themselves.
The project is available free of charge under the GPL license, with no paid plan structure described. That keeps the software suitable for organizations that prefer open-source deployment and direct control over monitoring infrastructure. Self-hosted operation also places responsibility for deployment, configuration, maintenance, alert setup, and dashboard availability with the team running Xymon. Configuration can be customized across hosts, services, alerts, graphs, and tasks, supporting environments where monitoring rules need to match local operating practices.
Its feature set covers HTTP, FTP, SSH, SMTP, LDAP, ping, and other network services, alongside CPU, disk, memory, process, and log monitoring. Process-count checks can match configurable command-line patterns, while log monitoring can change status based on patterns. Web-based status dashboards, configurable service-failure alerts, historical status tracking, and RRD trend graphs add operational visibility over time. Xymon is a strong choice for Unix-focused teams seeking configurable, self-hosted monitoring without a subscription. Teams needing broader platform coverage, a hosted service, or a wider ecosystem fit should consider alternatives with those priorities.
