LibreNMS is a fully featured network monitoring system that discovers and monitors network devices, interfaces, and services.

  • Monitoring & Logging
  • Network Services
  • Productivity
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.

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

First-install notes

  • Check SSO login settings If you set up single sign-on (SAML/OAuth), run `lnms config:get auth.socialite` to see the saved login settings. This helps you catch a wrong provider or token before users cannot log in. source
  • Start Varnish if you added caching If you added the Varnish page-cache option, use the service tool (systemctl) to start it: `systemctl start varnish`. If it is not running, the cache settings will not work and LibreNMS pages may load slower. source
  • Unraid first-use settings Create the database with CHARACTER SET utf8 COLLATE utf8_unicode_ci, and follow the Unraid forum thread in the app links for Poller setup. source

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.
