KNOB REFINEMENT TECHNIQUES

A system and method for knob refinement. A method includes determining an ordered list of knobs organized with respect to impact on the target metric for a system based on a plurality of historical sets of target metric measurements; determining a second system configuration based on the ordered list of knobs and a first set of target metric measurements recorded for the system when the system is configured according to a first system configuration, the system having a plurality of knobs, wherein the second system configuration includes at least one knob of the plurality of knobs that is reconfigured as compared to the first system configuration; and applying one of the first system configuration and the second system configuration, wherein the applied system configuration is determined based on the first set of target metric measurements and a second set of target metric measurements.
