# LibreNMS LibreNMS is a fully featured network monitoring system that discovers and monitors network devices, interfaces, and services. It is open source and self-hosted, installable on Docker Hub, Proxmox, Kubernetes (Helm) and Unraid. Canonical page: https://ourlocalhost.com/app/67/librenms ## Description LibreNMS is a fully featured network monitoring system that discovers and monitors network devices, interfaces, and services. It collects metrics, applies thresholds, and shows dashboards for uptime, traffic, and device health. It suits home labs and small production networks that need self-hosted Simple Network Management Protocol (SNMP) monitoring. Use it for a free, community-supported alternative to commercial network monitoring tools. ## Platform availability Available on 3 of 9 platforms: Unraid, Proxmox, Helm. ## Health score 76/100 (Good), based on 4 of 4 factors. - Maintained: 100 (last commit 17 days ago) - Popular: 74 (4,939 GitHub stars) - Easy to install: 55 (3 install platforms, install notes, Docker image) - Light to run: 40 (4 GB minimum RAM, runs on ARM) ## Links - Docker Hub: https://hub.docker.com/r/librenms/librenms/ - Proxmox: https://community-scripts.github.io/ProxmoxVE/scripts?id=librenms - Kubernetes (Helm): https://artifacthub.io/packages/helm/midokura-community/librenms - Unraid: https://ca.unraid.net/apps/librenms-0saydqn1tohn4r?q=librenms - Official website: https://www.librenms.org/ - GitHub: https://github.com/librenms/librenms - Documentation: http://docs.librenms.org ## Common questions ### What database settings does the Unraid first-use thread recommend for LibreNMS? Create the database with CHARACTER SET utf8 COLLATE utf8_unicode_ci. Then follow the thread's instructions for Poller setup. ### How can I verify SAML or OAuth settings after configuring single sign-on? Run lnms config:get auth.socialite to inspect the saved login settings. This helps catch a wrong provider or token before users cannot log in. ### Does LibreNMS have native mobile apps? Yes, native iPhone and Android apps are available and provide core functionality. ### Where can I find Docker installation details for LibreNMS? Docker image documentation is located in the LibreNMS/Docker GitHub repository. Images are available on Docker Hub and Quay. ### How can I identify devices causing LibreNMS pollers to run longer than 300 seconds? Open /poll-log/ in the web interface and find the devices with the longest run. Then check Graphs -> Poller -> Poller Modules Performance to find the slow modules. ## Alternatives - Beszel: A lightweight server monitoring hub with historical data, docker stats, and alerts. - Cacti: Cacti is a complete frontend to RRDTool, it stores all of the necessary information to create graphs and populate them with data in a MySQL… - Icinga: Icinga is a fork of Nagios and is backward compatible. - Munin: Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?&q… - Nagios: Nagios is an open-source monitoring system that checks hosts, network services, and IT infrastructure resources so IT administrators can id… - NetAlertX: NetAlertX is a self-hosted network presence scanner and alert framework that monitors Wi-Fi or LAN devices, detects new, disconnected, or c… - Observium: Observium is a free and open-source, autodiscovering network monitoring platform. - OpenNMS Horizon: OpenNMS is an open-source network monitoring platform that helps you visualize and monitor everything on your local and distributed network… - Paessler PRTG Network Monitor: Comprehensive network monitoring includes up/downtime tracking, traffic analysis, and performance metrics using SNMP, WMI, and NetFlow prot… - Spiceworks: Free help desk platform for IT provides ticket management, network monitoring, asset inventory, remote access, task prioritization, and aut… - Zabbix: Zabbix is an enterprise-class, open-source distributed monitoring solution designed to monitor the performance and availability of network… - dash0: Full-Stack Infrastructure Monitoring without Limits. --- Source: Our Local Host (https://ourlocalhost.com/app/67/librenms), the self-hosted and open-source app directory.
