Understanding HP WebQoS
How WebQoS Fits Into Your Environment
Chapter 1 17
WebQoS Components
WebQoS comprises a number of components that perform priority-based
resource management and service request handling. (See Table 1-1,
“WebQoS Components.”) In addition, management components allow you
to configure WebQoS for the systems on which it is installed as well as
define the service level objectives (SLOs) and threshold policies that are
important to your business. (For an explanation of SLOs, refer to
“Service Level Objectives for Site” on page 158.)
Note that not all components are required on every WebQoS-enabled
system. Refer to Figure 1-2, "Request and Management Data Flow", to
understand how these components fit into the WebQoS picture.
