The tree view provides an automatically populated representation of the actual physical hierarchy of blade components. For example, blades within enclosures within racks and is a good place to create and utilize collections of components.
When a collection is selected in the Systems and Events panel or from the system table view page or event table view page, the tree view is displayed in the workspace. The tree view is initially collapsed. Systems might appear in multiple locations, because they can be in multiple collections. Users can view only systems that they are authorized to see. Therefore, if a user is not authorized to view a particular system in the tree, that branch is not displayed. The following sections are available on the tree view page:
Expanding the tree view
Branch nodes can be expanded by clicking the toggling expansion icon. However, the system name is not an expansion control, but a drilldown. When a branch is collapsed, the icon appears as . When clicked, the branch expands to show the child systems, and the icon toggles to . Clicking the icon again collapses the branch and toggles the icon back. A paging mechanism is provided in the branches. When a branch is expanded, the first 100 systems are displayed. To view additional systems, click next...of.... Clicking this link displays the remaining systems, up to 100. If only one system remains in the next page, it is simply added to the page in place of the next link. At the top of each tree view there are two expansion buttons. To expand all branches of the tree, click . To collapse all branches of the tree to first level branches, click . If there are too many systems to load into the expand all page, a popup message appears stating that there are too many systems in the tree and the function cannot be performed.
Selection in the tree view
The selection control for the tree view cycles through four states using the following check icons:
First, initial state, nothing selected.
Second state, both the container and the contents are selected. If the contents were not already expanded, the next level of children are expanded to show the selection.
Third state, all of the contents are recursively selected. The children are expanded (if not already) to show they are selected. Only the next level is expanded.
Fourth state, just the container is selected.
Tree view status
The tree view displays status data for each system. The status icon is located in the left of the tree view next to the selection checkbox. If the status of the systems is Unknown, no status icon appears. If the systems are containers, the status to the left of the container name is shown as the most critical status of the systems in the container, including the container status. The status of the container itself is displayed to the right of the system name along with a system type label.
Available drilldowns
The tree view contains hyperlinks for the system name and status icon drilldowns. If a system name is clicked, the System Page for that particular system appears. The status icons drilldown to the status URL for that system, unless the status icon is the status icon to the left of a container. Clicking on the roll-up status of a branch loads a table view of all the systems in that branch which match the roll-up status. Thus, you are presented with all the systems that are contributing to the severity of the roll-up status.
Selection states for collections
In the tree view, you cannot select a collection and the members of the same collection simultaneously. When a collection is selected, the members are displayed and their selection boxes are disabled. The selection states for a collection are as follows:
The initial state, nothing is selected
The collection itself is selected and the contents of the collection are disabled
.
The members of collection are selected; the collection itself is unselected
Additionally, there is a checkbox at the top of the tree that enables you to select the collection that is being viewed. When the checkbox is checked, all the checkboxes under the collection are cleared and disabled. When the checkbox is deselected, the checkboxes under the collection become selectable.
Tree view buttonsThree buttons at the bottom of the tree view page are available to users with full configuration rights.
[Save selection as]. When a system or group of systems is selected, this button is used to save the selection with a new name. Changes are saved on a per-user.
[Delete]. This button is used to delete one or more systems from the database. Select the systems to be deleted, and click [Delete]. A dialog box appears. Click [OK] to continue with the deletion or click [Cancel] to cancel the operation. The tree view is refreshed.
[Print]. Click [Print] to display a printable version of the tree. Print the tree from the browser by clicking File Print.
[Print] is available regardless of your rights, however the other options are only enabled if you have appropriate rights.
