LibreNMS
What it is
LibreNMS is a free, self-hosted network monitoring system with support for a range of devices. It can discover networks automatically using CDP, FDP, LLDP, OSPF, BGP, SNMP, and ARP. Users can configure alerts 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 functions include VLAN, ARP and FDB collection, traffic billing, syslog, service monitoring, traffic monitoring, topology maps, 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 assistance is available through Discord and a forum, while commercial SLA-backed support and consultancy are offered through partners.
