  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.
