Engineered by Sysadmins. Built for Scale.

Built From the User's Perspective

Nagios Core has earned its place as a rock-solid, highly dependable monitoring engine. However, for the sysadmins tasked with running it in production, raw Nagios Core traditionally meant wrestling with complex text configuration files, fragmented web interfaces, and manual command-line scripts.

NEMS Linux was created to solve that exact pain point. Designed directly from a practitioner's perspective, NEMS Linux takes the proven reliability of the Nagios Core engine and wraps it in a complete, unified appliance. We eliminated cryptic config files, integrated modern management tools, and automated the entire workflow so IT teams can focus on running their networks, not managing their monitoring server.

A Complete, Cohesive Monitoring Platform

Over ten years of continuous development, NEMS Linux has evolved far beyond a basic monitoring tool. It is a fully integrated ecosystem designed to give enterprise IT teams an out-of-the-box management experience with:

• Zero Raw Config Files: Intuitive web-based management with automated syntax validation before changes go live.
• NEMS Tactical Overview: Out-of-the-box NOC display for server room TVs or background browser tabs, featuring real-time status monitoring and spoken audible alerts.
• Native APIs & Automation: RESTful API access for programmatic control, host status queries, and workflow integration.
• Multi-Channel Alerting: Out-of-the-box notification hooks for Microsoft Teams, Slack, Discord, Telegram, Email, Pushover, SMS and more with Webhooks without writing custom scripts.
• Built-in Disaster Recovery & Failover: Automated configuration backups via NEMS Migrator and external "monitor the monitor" uptime checks through NEMS CheckIn.

Enterprise Power at a Palatable Price

Enterprise IT departments shouldn't be penalized with skyrocketing software bills every time they deploy a new virtual machine, switch, or cloud resource. While commercial competitors build business models around restrictive host tiers and per-element licensing traps, NEMS Linux offers a predictable, business-friendly structure:

• NEMS Linux Enterprise: A flat annual subscription covering unlimited hosts and services, cloud services, and 3 SLA support incidents, with zero per-device fees or database licensing add-ons.
• NEMS Linux SOHO: 100% free forever for home labs and small-site deployments.

By placing usability, turnkey deployment, and total cost predictability at the center of our vision, NEMS Linux delivers the most refined and complete Nagios Core appliance experience available.
