Librenms

App in the BluixApps catalog

What it is

LibreNMS is a network monitoring system — auto-discovers devices via SNMP, tracks port utilization, alerts on bandwidth / availability, supports 200+ device vendors (Cisco, Juniper, MikroTik, Ubiquiti, HP, Aruba, Fortinet). The OSS heir to Observium's legacy.

For network engineers responsible for keeping networks alive, LibreNMS is the established self-hosted monitoring choice.

What it's for

  • Network device monitoring — switches, routers, firewalls, APs, servers
  • Bandwidth tracking — per-port utilization over time
  • Alerting — email / Slack / webhook on threshold breach
  • Topology mapping — auto-generated network diagrams
  • Inventory management — track device firmware, vendors, locations

Who it's for

  • Network engineers managing multi-vendor enterprise networks
  • MSPs monitoring customer networks at scale
  • ISPs tracking network health across infrastructure
  • Sysadmins monitoring server + network in one tool
  • Hosting providers giving customers network visibility

Why teams pick LibreNMS over alternatives

  • GPL-3.0 — fully open, commercial use clear
  • 200+ vendor support — most comprehensive in OSS NMS
  • Auto-discovery — find devices via SNMP without manual config
  • Alerting flexible — extensive transport options
  • Multi-tenancy — separate views per customer (MSP use case)
  • Active development — frequent releases, strong community

Integrations

  • Protocols — SNMP v1/v2c/v3, ICMP, WMI, IPMI for sensors
  • Vendor support — Cisco, Juniper, MikroTik, Ubiquiti, Aruba, HP, Fortinet, Palo Alto, Sophos
  • Alert transports — email, Slack, Discord, PagerDuty, Telegram, MS Teams, webhook, custom
  • Authentication — local + LDAP + Radius + AD
  • API — REST API for programmatic device management
  • Maps — geographic + topology auto-discovery
  • Smokeping integration — ping latency tracking

Notable users & community

  • 4k+ GitHub stars
  • Used by ISPs and MSPs worldwide
  • Active community + IRC channel
  • Long-running OSS project (fork of Observium)
  • Featured in network monitoring tool roundups

Tips & operations

  • Use SNMPv3 in production — SNMPv2c sends credentials in cleartext
  • Poller scaling — single poller fine for <100 devices; distributed pollers for thousands
  • Configure RRD via Cache — RRDCached speeds up RRD writes significantly
  • Persistent storage — MySQL + RRD files + logs all need volumes
  • Mind disk I/O — RRD writes are I/O heavy; SSD recommended
  • Backup MySQL + RRD — both essential for historical data
