    To specify a value, in percentage, to represent the estimated monthly growth on CPU Utilization Growth, Memory Utilization Growth and Storage Utilization Growth in the next 12 months, do one of the following:

    • Click Use default growth to use the default value as specified in the Reservations Settings page. This option is selected by default.
    • Click Specify custom growth to use a custom value. Type a value in the % / month box, or to use the measured trend value, click . That value is copied in the % / month box.

  5. Click Save.
    After you specify thresholds at the Capacity Pool level, the threshold for all Reservation Targets associated to the Capacity Pool are updated to use the same value. If a Reservation Target belongs to different Capacity Pools, the most recently updated threshold is applicable. If you explicitly set thresholds at the Reservation Target level, the value, if specified, at the Capacity Pool level is overridden.

    If a Reservation Target belongs to different Capacity Pools, the latest trend value is applicable. You cannot override this value for a single Reservation Target. It is recommended that you do not share a Reservation Target between multiple capacity pools.
