The Critical Nodes panel displays nodes that are in a critical state. If there are no critical nodes, this panel does not appear.
A node is critical if one or more resources associated with the node are critical. Only nodes that have at least one resource in a critical state are displayed. For example, if a file system associated with the node is critical, the node is displayed in the panel.
To view all nodes regardless of the state, click View All Nodes.
For each node, you can click View to view the node dashboard. For information about the dashboard, see Monitoring node performance.
