Work in Progress
This page is a work in progress.

Nodes section and various server services sections still need to be written.

The status of the SOWN network is continuously monitored by Icinga. Further details of the status of the servers and Wi-Fi nodes are available. The locations of these nodes are displayed on the SOWN network map.

Servers

These monitored to check that they are online and will be described as either UP or DOWN. Servers are broken down into two main categories Production and Development. This is indicated by their colouring on SOWN's topology.

Services

Services on production servers count towards the Service Status percentage whereas services for development servers do not.

There are numerous services monitored across all servers. Generally these services should show as OK indicating the server is behaving as expected. There are some generic services monitored across most if not all servers:
