About Extended Dimensions
The Insight Server (InsightServer64.exe) enables you to define custom dimensions from event data or lookup data.
Any custom dimensions that you define are referred to as extended dimensions. You can use them to create visualizations, build extended metrics, or perform analysis to understand the operations and issues associated with your business channel. You can define several types of extended dimensions in the Transformation.cfg file or in Transformation Dataset Include files.
An extended dimension represents a relationship between log field values and a parent dimension. A parent dimension can be any user-defined countable dimension. See Countable Dimensions . You specify the parent when defining the dimension in the Transformation.cfg file or a Transformation Dataset Include file. A dimension's parent is the same as its level. For example, if you define a dimension with a parent of Session, then that dimension is a session-level dimension.
The log field values can come from the inherent values available in the log ( .vsl) files or other event data sources or from extended log fields created through the use of transformations.
To add an extended dimension to a visualization, you access it from the Extended list within the Select Dimension menu. For example, to add an extended dimension to a graph visualization, you would right-click within the workspace and click Add Visualization > Graph > Extended > < dimension name > . If you would like to organize the list of your extended dimensions within the data workbench interface, you can move the extended dimensions into subfolders that you create. See the Administrative Interfaces chapter of the Data Workbench User Guide . If you do this, the subfolders' names also appear in the menu, as in Add Visualization > Graph > Extended > < subfolder name > > < dimension name >.
To see all the dimensions that have been defined for your dataset profile and the buffer size for each, open the Detailed Status interface in data workbench and click Performance , then Dimensions to expand the nodes. The buffer size, which controls query times, is expressed in MB. For more information about the Detailed Status interface, see the Server Administration and Installation guide.
