Conﬁguring HP WebQoS

The following sections describe the parameters that can be set using the

HP WebQoS Peak Session Settings administration web page. See “HP

WebQoS Conﬁgurable Parameters” on page 36 for a list of the available

conﬁgurable parameters for the Netscape server and a list of defaults

already conﬁgured in config.ac.

Admission Control

Determine when to admit a session.

The default value is to always admit all sessions.

Parameter Description

Always Admit Disable HP WebQoS and admit all arriving sessions.

If you are permanently disabling HP WebQoS, you should

remove HP WebQoS from your system (see “Removing HP

WebQoS” on page 34 for more information).

Load The maximum CPU utilization or number of jobs in the run

queue allowed by the system. Can be used with response time

to control session admission.

If the average system load is less than the speciﬁed threshold,

all sessions are admitted. If the average system load equals or

is greater than the speciﬁed threshold, no new sessions are

admitted. Only requests that are part of a current session are

processed.

When a new session is not admitted, a corrective action is

taken.

The load threshold is a number greater than zero. If it is in the

range from zero to one, it corresonds to the average CPU

utilization (for example, 0.95 corresponds to a 95% CPU

utilization). If the load is greater than one, then the CPU

utilization is 100% and the value is the average number of jobs

in the run queue.

The average system load is calculated every ﬁve seconds and

uses the following formula:

average_load = (20% * current_load) + (80% * average_load)
