Observium

Observium is an autodiscovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and many more. Observium has grown out of a lack of easy to configure network monitoring platforms. It is intended to provide a more navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, being completely autodiscovered with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.
