Presenting collected Nagios data has been cumbersome. But now with op5 added funtionality, storing the data in a database makes it much easier. Morten Bekkelund has created a nice dashboard typically used in NOCs. The dashboard has been modified and improved by the community and an example can be seen at op5 sandbox dashboard and [...]

Markus Almroth, describes Sysnagios which did the opposite of most monitoring projects. Sysnagios decentralized the configuration of systems and network monitoring in a controlled way. [...]
