Librenms
LibreNMS is an SNMP network monitoring system and IT infrastructure management suite. It serves as an automated network discovery tool and infrastructure dashboard, enabling the identification and monitoring of network hardware and operating systems.
The system differentiates itself through a rule-based alerting engine and a comprehensive IT incident workflow integration. It supports complex alert routing, including escalation sequences and direct ticket generation for project management and service desk platforms.
Its observability capabilities cover multi-vendor hardware oversight, application performance tracking, and security monitoring. The platform gathers metrics via poll-based collection, remote agents, and a script-based extension system to visualize performance data across distributed networks.
The project provides programmatic interfaces and external system integrations for automating network hardware management.
