  • Hi,

     

    'Preferred' is referring to the preferred load balancing method used in the pool which the bigip tries first and the value (100) is how many times this method has been selected. Global 'Picks' value (100) is how many times that pool member has been selected.

     

    Kind regards

    Ben
