~Performance Queries: Defining Comparison Categories~

After performance query activities are selected, definition of the comparison categories (such as location, day of week, CPU speed, etc.) need to be selected. Each comparison category selected appears in a separate column in the Grid view, and in a separate row in the Drill Down Stack in the Chart view.

The group of comparison categories selected is called the Selected Categories List. Once the Selected Categories List is created, it should be sorted according to level of priority.


The Selected Categories List is not relevant to an Influencing Performance Factors performance query, since this type of query automatically utilizes all comparison categories.

Creating a Selected Categories List

Building a Selected Categories List involves composing a selected set of desired comparison categories. Any combination of categories can be included in the list.

Comparison categories that are available for selection vary according to the category group that is currently displayed. The category groups are:

  • Typical: A predefined list of the most commonly selected comparison categories
  • Contextuals: All contextual attributes, including product name, monitor type, server ID, etc.
  • All Attributes: All static attributes, including CPU speed, location, memory, etc.
  • Time: Parameters related to time, such as day of the week

Time is a special attribute that must be selected as the first attribute for time comparison to actually be done.

Originating vs. Frontline Comparison Categories

When defining comparison categories involving Citrix XenApp (ICA) or Remote Desktop (RDP) applications, it is important to specify whether the comparison attributes are related to the Citrix client or the Citrix server. For example, if the selected comparison category is Subnet, the performance query should indicate whether comparison should be according to server or the client Subnet.

The Comparison Categories tab enables you to select the following specifications for the relevant comparison categories:

  • Originating: End Points which are running the applications
  • Frontline: End Points on which End Users are physically using the application, e.g., remote desktops connecting to Citrix XenApp (ICA) servers, or desktops that are physically used and are running the application

Sorting the Selected Categories List

The order in which categories appear in the Selected Categories List reflects the level of priority of the categories. The category that appears first has the highest priority. Level of priority determines the hierarchy in which categories are displayed when drilling down in Chart views.

Drag-and-drop can be used to sort the selected categories into the desired order of priority.
