CLARIN-D monitoring requirements

The monitoring requirements of CLARIN-D are pretty modest - a simple icinga or nagios installation would be sufficient to fullfill all the needs:

• regular checks if hosts are up and reachable (ping)
• regular checks if certain network services are working (e.g. http)
• Each center can provide ​nagios plugins to assess the state of that center's services.
• Each center can register one or more contact persons. They will get an email with a warning if a host or service is not working correctly.
• The server running the monitoring software is also monitored itself.
• Users (not only the center administrators) should be able to see the status of each center and its service(s) on a website.
• For access to the web interface of icinga/nagios authentication & authorization via shibboleth would be nice.

Visualisation for Clarin-D: map of germany under ​http://de.clarin.eu/status with traffic light alarm indication (?) maybe ​like this (?)

Open questions: Do we need graphs to see how long or how often services have been unavailable in the past? Perhaps via link to nagios?
