Forecasting THP pools utilization

XP Performance Advisor enables you to forecast percentage of THP pool utilization for the next one

week or one month. It also allows you to determine when a THP pool utilization can cross the next

threshold level, and when an alarm be generated. For more information, see “Forecasting THP's

performance” on page 371.

IMPORTANT:

• You can forecast percentage of utilization only for THP pools.

• The Forecast list is displayed on the Alarm History screen only when you select the Utilization

metric for a THP pool.

To forecast percentage of utilization for a THP pool:

1. Click Alarms in the left pane and select the Alarms History tab on the Alarms screen.

The Alarms History screen appears.

2. Select Forecast Week or Forecast Month from the Forecast list. By default, No Forecast is selected.

Based on your selection and the percentage of utilization of a THP pool, XP Performance Advisor

appends the forecast information to the email notification that is sent when an alarm is generated.

This forecast information provides the time when the THP pool utilization cross the next threshold

level. Following is a sample email notification that has the forecast information appended to the

email notification text:
