  - Alerts
    The Alerts page shows all the latest alerts in the system. It lets you view the alerts in different modes, and carry out actions on the alerts.
  - Assets
    The Assets page shows all the physical components and systems in the local network environment and their associated details. It also lets you perform actions on those assets. Depending on the nodes and components involved, assets can range from a simple personal computer to an operational technology (OT) device.
  - Queries
    You can use the Nozomi Networks Query Language (N2QL) syntax to create complex data processes to obtain, filter, and analyze lists of information from the Nozomi Networks software.
  - Smart Polling in Guardian
    The Smart Polling page lets you view and manage Smart Polling.

  - Network
    The Network page gives you access to multiple pages that show nodes, links, sessions in tabular format and graphs and traffic in a graphical format.
  - Graph
    The Graph pages gives a graphical representation of the nodes in the environment.
    - Network
      The Network page displays a live graph of connected assets, links, and filters in your network. You can apply filters, adjust the layout, and select node and link perspectives. Interactive options let you customize the visualization and export reports.
    - Assets
      The Assets page shows linked assets as graph vertices when available, and defaults to node display when no asset is associated. This view provides a contextual representation of asset relationships within the network topology.
    - Physical
      The Physical page displays a real-time interactive map of all physical device connections in the network. Nodes are shown only if a physical link has been detected for them. The graph, shows how devices connect at the cable level. It is a live, visual way to understand your physical network layout down to the port.
    - Graph controls
      A list of the different control options in the graph view.
      - Layout
        The Layout dropdown lets you select a layout for the graph.
      - Magic wand
        The magic wand icon opens a wizard to help filter the graph and view only the desired information to help you reduce visualized data from large graphs.
  - Process
    Process is a set of repeatable functions that a business does to deliver a core value.
  - Reports
    The Reports page lets you manage, generate, schedule and view reports.
  - Assertions
    The Assertions page shows all the assertions and lets you configure them.
  - Time machine
