Subnet Status shows the current status of switches and HFIs. It tells a user that in the past time window (defined in setup wizard), how many switches/HFIs are under critical, error, warning, or normal status and are measured based on notices from the Fabric Manager. If one node has multiple notices within a time window, it is counted by the notice with the highest severity level. The map between notice and severity is customizable with the setup wizard. Choose either pie chart or bar chart with the icon on the right side of the title bar.
