weighted CPU% = (MonitorCPUWeight% * current CPU) +

[(100 - MonitorCPUWeight)% * previous CPU]

For example, if you set the MonitorCPUWeight to 20, the current

CPU utilization is 60, and the previous CPU utilization is 50, the

weighted CPU utilization is (20% * 60) + [(100 - 20)% * 50] or 52%.

If you want to monitor the current CPU utilization only, set this

parameter to 100.

The MonitorInterval parameter determines how often the weighted

CPU utilization is calculated (default is every 5 seconds).

If you modify MonitorCPUWeight, you must restart the SCA and your

web server.

• MonitorInterval - Default: 5 seconds

How often, in seconds, threshold policies are monitored. The

minimum value is 5 seconds. If you change the value, you must

restart the web server.

• MonitorResponseTimeWeight - Default: 50%

Percentage of the current response time used to calculate the

weighted response time. The weighted response time is based on the

current and previous (last measured) response time:

weighted response = (MonitorResponseTimeWeight% * current

response time) + [(100 - MonitorResponseTimeWeight)% * previous

response time]

For example, if you set the MonitorResponseTimeWeight to 20, the

current response time is 3 seconds, and the previous response time is

2 seconds, the weighted response time is (20% * 3) + [(100 - 20)% * 2]

or 2.2 seconds.

If you want to monitor the current response time only, set this

parameter to 100.

The MonitorInterval parameter determines how often the weighted

response time is calculated (default is every 5 seconds).

• NumOfDeferredSessionsPerMinute - No default

The number of sessions that can be deferred per minute. If the value

is greater than 60, then the parameter

NumOfDeferredSessionsPerSecond automatically increases.

• NumOfDeferredSessionsPerSecond - Default: 1
