const (
	// IndicatorLevelLowerBound is usually used to define the lower bound to define
	// service working states. For instance, if rpc-latency is defined as a
	// business indicator, if actual observed value is below IndicatorLevelLowerBound,
	//	it means the workload works perfectly; if observed value is above
	// 	IndicatorLevelLowerBound but below IndicatorLevelUpperBound, it means the workload
	//	works can still work, but may suffer with performance downgrade.
	IndicatorLevelLowerBound = "LowerBound"

	// IndicatorLevelUpperBound is usually used to define the upper bound that
	// the workload be bear with. For instance, if rpc-latency is defined as a
	// business indicator, if actual observed value is above IndicatorLevelUpperBound,
	// it means the workload is broken and can't serve the online traffic anymore.
