Replacements

Listings that take over the same core job as NetXMS.

  • Zabbix

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

    FreeOpen sourceLinuxWebSelf-hosted

    Zabbix is free under AGPL-3.0 and scales to tens of thousands of devices with proxies, but its configuration is extensive and the learning curve is real.

  • LibreNMS

    Discover and monitor network equipment from a central server.

    FreeOpen sourceSelf-hosted

    LibreNMS is free under GPL-3.0 and focuses on discovering network equipment with alerting and historical graphs, though visibility depends on supported protocols and credentials.

  • OpenNMS

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

    FreemiumOpen sourceSelf-hosted

    OpenNMS is an open-source carrier-grade platform with event correlation and Grafana integration, but its complexity may be overkill for small networks and paid tiers cover enterprise support.

  • Checkmk

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

    FreemiumOpen sourceSelf-hosted

    Checkmk adds agent-based and SNMP auto-discovery to reduce manual setup, while advanced features and scaling sit behind its paid commercial editions.

  • PRTG Network Monitor

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

    FreemiumProprietaryWindowsWebSelf-hosted

    PRTG is closed source and runs on a Windows server, with 100 free sensors and autodiscovery, maps and alerting in one interface, but per-sensor licensing gets expensive.

  • Observium

    Autodiscovering network monitoring platform with a clean interface.

    FreemiumProprietaryLinuxWebSelf-hosted

    Observium is not open source; devices appear automatically through autodiscovery, but alerting sits in the subscription edition and the community edition gets fewer releases.

  • Icinga 2

    Monitor infrastructure availability with a configurable checking and alerting system.

    FreeOpen sourceSelf-hosted

    Icinga 2 is free under GPL-3.0 and focuses on availability checks and notifications with distributed setups, though a full deployment needs configuration and optional web components.

  • Nagios Core

    Monitor hosts and services with a configurable alerting engine.

    FreeOpen sourceSelf-hosted

    Nagios Core is free under GPL-2.0 and runs plugin-based host and service checks, but configuration and many checks need manual setup or extra plugins.
