Observium

Observium is a PHP / MySQL-based Network Observation and Monitoring System (NOMS) which collects data from devices using SNMP and presents it via a web interface. It makes heavy use of the RRDtool package. Observium has a number of simple core design goals driving its development: minimum interaction, maximum automation and maximum accessibility of information. These design goals have resulted in a slightly unconventional monitoring system with almost no individually customisable settings per device, and where almost everything that can be monitored is automatically discovered.

  1. I have recently come across Glances, which seems good for individual system monitering. I have not tried it yet though.

  2. Librenms , being using to manage automatic backup of network devices, cisco etc. Very simple to setup.

  3. You spelled Icinga wrong. It’s not “Incinga”, as your screenshot and link to the homepage show.
