Observium is an open source, low-maintenance, auto-discovering network monitoring tool for operating systems and network hardware. It supports Linux and Windows operating systems and network hardware like Cisco, Juniper, Brocade, Foundry, HP.
Observium is based on AMP (Apache, MySQL, and PHP) stack and it collects the monitoring metrics via SNMP protocol. It uses RRDtool to make a graph of metrics collected from SNMP. Observium can also collect data using CDP, FDP, LLDP, OSPF, BGP, and ARP protocols.
Observium comes with a simple yet powerful interface to monitor devices, and it’s alerting system can be highly customized to receive alerts over an email, IRC, slack and more.
This tutorial covers the installation of Observium on CentOS 7 / Ubuntu 16.04 / Debian 9 and collecting usage metrics from Linux machines via SNMP protocol.
