What LibreNMS is
LibreNMS is a free, self-hosted network monitoring system with device support. It can discover networks automatically using CDP, FDP, LLDP, OSPF, BGP, SNMP, and ARP. Customizable alerts can be sent through email, IRC, Slack, and other transports, while the API can manage installations, create graphs, and retrieve data. Distributed polling supports horizontal scaling. Documented network tools include VLAN, ARP and FDB collection, traffic billing, syslog, service monitoring, and customizable dashboards. Integrations include Oxidized, RANCID, NfSen, Smokeping, Graylog, and Nagios plugins. Authentication options include MySQL, LDAP, Active Directory, and HTTP, and two-factor authentication is documented. Installation guides cover CentOS and Ubuntu, with Docker images also available. Native iPhone and Android apps provide core functionality, and an online demo is available before installation. Community help is available through Discord and the community forum; commercial SLA-backed support and consultancy are offered through partners. The listed plan costs nothing, with commercial support available through those partners.
