Discover and monitor network equipment from a central server. The listings below can replace it for an important use case. Each note says what changes if you switch.

Replacements

Listings that take over the same core job as LibreNMS.

  • Observium

    Autodiscovering network monitoring platform with a clean interface.

    FreemiumProprietaryLinuxWebSelf-hosted

    Observium offers autodiscovery with a clean interface, but it is not open source and alerting sits in the paid subscription edition.

  • Zabbix

    Enterprise-scale open-source monitoring for networks and applications.

    FreeOpen sourceLinuxWebSelf-hosted

    Zabbix covers networks and applications at enterprise scale with proxies and templates, licensed AGPL-3.0, though configuration is extensive.

  • Cacti

    RRDtool-based graphing and monitoring for network devices.

    FreeOpen sourceLinuxWebSelf-hosted

    Cacti graphs network devices with RRDtool storage and a mature template ecosystem, but has a dated interface and needs plugins for alerting.

  • OpenNMS

    Carrier-grade open-source network monitoring platform with event correlation.

    FreemiumOpen sourceSelf-hosted

    OpenNMS adds carrier-grade event correlation and Grafana integration, but is complex for small networks and has paid tiers for enterprise support.

  • NetXMS

    Monitor network devices, servers and infrastructure through a central platform.

    FreemiumOpen sourceSelf-hosted

    NetXMS monitors network devices, servers and infrastructure with management interfaces, with enterprise editions under separate terms.

  • PRTG Network Monitor

    Sensor-based network monitoring, free for the first 100 sensors.

    FreemiumProprietaryWindowsWebSelf-hosted

    PRTG offers sensor-based monitoring with autodiscovery and maps, free for 100 sensors, but is closed source, Windows server only and licensed per sensor.

  • Checkmk

    Hybrid open-source and commercial monitoring with agent-based and SNMP auto-discovery.

    FreemiumOpen sourceSelf-hosted

    Checkmk adds agent-based monitoring alongside SNMP auto-discovery, but advanced features and scaling require paid commercial editions.

  • ManageEngine OpManager

    Zoho's network monitoring software for routers, switches and hybrid infrastructure.

    FreemiumProprietarySelf-hosted

    ManageEngine OpManager covers fault, performance and configuration management in one console, but is proprietary and larger networks need paid tiers.

Also worth comparing

These listings name LibreNMS as their own alternative, so the relationship runs both ways.

  • Icinga 2

    Monitor infrastructure availability with a configurable checking and alerting system.

    FreeOpen sourceSelf-hosted

    LibreNMS focuses on discovering and monitoring network equipment with alerting and historical graphs, depending on supported protocols and credentials rather than service checks.

  • Naemon

    Community-run network and host monitoring suite built on the Nagios 4 core.

    FreeOpen sourceLinuxSelf-hosted

    LibreNMS is GPL-3.0 monitoring that discovers network equipment and provides alerting and historical graphs, focused on devices rather than Nagios-style checks.

  • SolarWinds Network Performance Monitor

    Industry-standard self-hosted network performance monitor with intelligent maps.

    PaidProprietarySelf-hosted

    LibreNMS is free and open source under GPL-3.0, discovers network equipment from a central server, and provides alerting and historical graphs without licence costs.
