Click the “threshold value setting” icon to set the warning threshold value for SGA state.
When it meets the level 1 threshold value warning condition, the yellow light displays; when it
meets the level 2 threshold value warning condition, the red light displays. You can use the
custom threshold or global threshold to set the threshold value. Pay more attention that the
higher the hit ratio index is, the performance is better, so the threshold condition ought to be
set to “Less than or equal to.”
