Column Groups Dialogs

Column groups allow you to format the events list to include only the relevant meta keys in the Events view and Legacy Events view (see Use Columns and Column Groups in the Events List). When the events list in Investigate is populated with events, each column lists the values returned for a meta key. Changing the meta keys displayed in the events list is a useful method of narrowing the focus of your investigation. For example, the default column group includes columns for Collection Time, Type, Theme, Size, and Summary. These are just the basic information, not specialized in any way. The NetWitness Email Analysis list has only that contain information useful when investigating email.

The column group definition includes the meta keys to use as column titles, the position of the column in the list, and the default width of the column. You can add, delete, import, export, and edit column groups. At fresh installation, built-in column groups are available. The built-in column groups are prefixed with NetWitness and can be duplicated but cannot be edited or deleted. You can also create custom column groups.

  • The Create Column Group dialog is for the 11.4 and later Events view. To access this dialog, select Column Group > New Column Group in the Events view toolbar.
  • The Column Group Details dialog is for the 11.4 and later Events view. To access this dialog, select Column Group in the Events view toolbar, then click the edit icon (netwitness_cgediticon.png) next to a custom column group name.
  • The Manage Column Groups dialog is for the Legacy Events view (Version 11.4) , and the Events view (Version 11.4 and earlier). The Manage Column Groups dialog has these features that are not yet available in the Create Column Group dialog: set column width, import, and export. To access this dialog, go to Investigate > Legacy Events and in the View drop-down list select Manage Column Groups. The View option is named for the current value, for example, Detail View, List View, Log View, or the currently selected column group.

After column groups are defined, you can use them in other Investigate views. In the Navigate view, Query Profiles allow you to select a column group to use when the profile is applied. In the Events view and the Legacy Events view, you can select a column group to apply to the Events panel.

This section introduces the Column Group Menu, Create Column dialog, and the Column Group Details dialog. The following figure is example of the Column Group menu. The table describes the options.


Feature Description
Visibility Options (Version 11.5 and later) Control the types of column groups that are visible in the list, using any combination of the visibility options (blue = selected, black = not selected):
Private = display private groups that only you can manage
Shared = display shared groups that anyone in your organization can manage
RSA = display built-in groups that only RSA can manage
The visibility options work together with the Filter Column Groups field. If the visibility option is hiding built-in groups (which include "RSA" in the group name) and you search for a name that contains "RSA," the list is empty.
Filter Column Groups Filters the list of column groups as you type text so that only group names that contain that text are displayed.
Column Group List The list of column groups consists of custom and built-in groups, which are distinguished by the icons that precede the name. In Version 11.5 and later, custom groups can be shared or private. The RSA column groups are built-in column groups. The icons distinguish the private custom groups, shared custom groups, and built-in groups.
New Column Group Displays the Create Column Group dialog, where you can create a custom column group.

The Create Column Group dialog, shown in the figure on the left, allows you to define a custom column group. The figure on the right illustrates the Column Group Details dialog, in which you can edit a custom column group. The table describes the fields and options in the dialogs.
