The Agent Dimension
The Agent dimension contains attributes that are derived from the "User Agent" string found in many Web server log files. User agents are typically Web browsers, but other agents such as Web spiders may also access sites.
This chapter contains the following topics:
Agent Dimension Hierarchies
The Agent dimension contains the following hierarchies:
The sections that follow list all levels in each hierarchy, followed by a diagram that provides a graphical representation of the hierarchy.
The Agent Client Software Hierarchy
This hierarchy contains the following levels, listed from top to bottom. For details about the attributes of each level, see Agent Dimension Levels.
- Client Type
- Client
- Client Version
- Agent
The Agent Operating System Hierarchy
This hierarchy contains the following levels, listed from top to bottom. For details about the attributes of each level, see Agent Dimension Levels.
- Platform
- Operating System
- Agent

Agent Dimension Levels
The Agent dimension is comprised of the following levels. For each level, information about each attribute (column name) is provided in the following format:
- Attribute: Description (example value)
levels are presented in descending order. In addition to the pre-defined attributes, each level contains five "generic" attributes that can be defined by the user.
