LibreNMS is a fully featured, community-driven GPL-licensed network monitoring system written in PHP with MySQL and SNMP. It auto-discovers network devices, collects metrics via SNMP pollers, and provides graphs, alerting, and a full API through a mobile-friendly web UI.

Use cases

• monitor bandwidth and health of routers, switches, and servers
• automatically discover all devices on my network via LLDP, CDP, and SNMP
• set up email or Slack alerts when a device goes down
• graph interface traffic and generate bandwidth billing reports
• scale monitoring across a large network with distributed polling
• self-host an open-source alternative to commercial NMS tools

When to choose

• you need auto-discovering SNMP monitoring for heterogeneous network hardware
• you want a self-hosted, GPL-licensed monitoring system with alerting and API access
• you need horizontal scaling via distributed pollers
• you want broad device support including Cisco, Juniper, HP, Linux, and FreeBSD

When to avoid

• you need application-level or APM-style monitoring rather than network/device monitoring
• you cannot run a PHP/MySQL stack or prefer agentless SaaS monitoring
• you need MIB-based dynamic sensor discovery rather than YAML/PHP definitions
• you want a lightweight single-binary monitoring agent
