Navigation tree overview

The navigation tree shows an at-a-glance synopsis of the events and views. Event and component folders are displayed in a hierarchical manner in the navigation tree.
The folders displayed in the navigation tree are divided into the following categories:

  • Global: When you create a folder under this node, all Infrastructure Management users can view and access that folder.
  • My Folders: When you create a folder under this node, only you can view and access that folder.


Folder and Component views are used as containers for groups, devices, and services. They are access control aware. Folders that contain monitor groups and devices are filtered based on the access control list in the CIs that the monitors and devices are associated with.

To further organize your display, you can add event and component folders, including folders for configuration items (CIs) associated with a service model, beneath these top-level folders, depending on your permissions.

The following table lists the icons for the objects in the navigation tree and provides a description for each object.



Navigation tree top-level node (Global). The Global node contains the following default collectors:

  • Event Collectors–displays the entire event collector hierarchy
  • Abnormalities–displays all the abnormality events
  • Services–displays all the services
  • Groups–displays all the groups
  • Devices–displays all the devices
    Based on permissions, users can create event and component folders under this node to organize the event view.
  • Monitors–displays a list of events for monitors created on the devices monitored by Infrastructure Management

Navigation tree top-level node (Mine). Based on permissions, users can create event and component folders under this node to organize the event view.

Event group collector; an event group subnode of the navigation tree top-level node or another event group node.

A CI is any component that needs to be managed in order to deliver an IT service. CIs are under the control of change management. CIs typically include hardware, software, buildings, people, and formal documentation, such as process documentation and SLAs. For more information about CIs, see Administering service models

Also, you can drag components from one folder that you create to another folder that you create within the navigation tree, and you can drag tiles from the Tile or Canvas view to an existing folder that contains the same type of component; for example, if the tile represents a device, then that tile can be moved to another device folder by using drag and drop. 

Users traversing the navigation tree can see and perform actions and operations on only those collectors to which they are granted access, based on different roles in the .mrl file of the collectors.
However, the collector-based permissions on events do not apply when you view an event list from the following locations:

  • Drill-downs from Groups, Services, Devices, or Monitors (Grid view and Tree view)
  • Abnormalities, Groups, Services,Devices, or Monitors nodes in the navigation tree
  • Parent event and component folders (not individual collectors within or outside the parent folders) 

In the navigation tree, the severity icons for a collector dynamically change depending on the severity level of the events for that collector. For example, if there is a Critical event on one of the devices, then the green icon changes to a red icon, indicating a Critical event. This allows you to see the status of devices on your system immediately.

By default, when you open the navigation tree, all nodes and subnodes are loaded even if a node is not expanded. If this causes performance issues, you can change how the navigation tree is loaded. For information, see Improving performance when the navigation tree is loaded in the operator console.
