  • Metric Identify defines the title of the metric used to judge these standards.
  • Time Grain Statistics defines the metric sampling kind.
  • The operator defines the comparability operator.
  • The edge defines the goal worth to set off this scaling criterion.
  • Period defines the period of time the dimensions standards will look again.

Motion

 

Right here we outline the motion that might be executed when the factors are met:

  • Operation defines which kind of operation we wish to execute, like rising or lowering the occasion depend.
