NMIS (Network Management Information System) was developed as an Open Source Network Management System to provide information to IT professionals to support decision making, both operational and longer term. The goal was to provide a dashboard of the all the nodes being managed in a single view so that it is possible to rapidly identify where problems are with traffic lights. People see information differently, and while some people see colours and arrows other see data textually, so for some people the details are lost in the colours.
In NMIS 8.5.6G we have returned to this goal and wanted to help people to view the data in different ways. We have done this by providing a new way to see the status of all nodes, this was done by introducing a trinary state, instead of just a node being UP or DOWN, nodes are now reachable, degraded or unreachable.
This page will describe some details on this new feature as well as the concept of the NMIS modes of classes, coarse and fine-grained for viewing status.
