Expanding the Navigator in increments

More indicators in the Navigator keep the tree compact. Click the indicator to open that branch of the tree. You can specify how many items to expand at one time.

About this task

When clicking expand Expand on a Navigator branch of more than, by default, 25 child items, you are prompted to enter the number to expand at one time.

Procedure

  1. Set the number of items to expand:
    1. If the Expand child items window is not open, right-click the Navigator item whose child items you want to expand incrementally and click expandExpand.
    2. Enter the number to expand and click OK to open that number of child items.
    3. Click More Navigator itemsMore when you want to open the next group of child items.
  2. Expand child items.
    You can expand all the child items of a Navigator item. The entire branch does not expand, just the children of the selected item. If the Expand child items window is not open, right-click the Navigator item whose child items you want to expand and click expand Expand Child Items.

Example

In large managed environments the expand feature helps you control the Navigator display and its performance. In this example, the expansion limit of 4 was chosen for the Windows Server child items:
  • collapse Enterprise Navigator item Enterprise
  •     collapse system platform Windows Systems
  •       collapse computer Computer1
  •         collapse agent Windows Server
  •           node Disk
  •           node Enterprise Services
  •           node Memory
  •           node Network
  •           More Navigator items More... 4 : 8

This example illustrates the result of selecting expand Expand Child Items at the platform level of the Navigator. The site is monitoring 500 Windows-based systems. The user can quickly see which systems have situation events and at what severity.

Logical and custom Navigator views

A custom Navigator view can be designed to show the same managed system more than once. If you have a managed system repeated somewhere else in the Navigator view, when you use the expand feature on one Navigator item for that managed system, any other items for that managed system will expand at the same time.
