Overview ¶
Package threshold provides CEL-based evaluation of performance thresholds. Threshold expressions use a single `value` variable (float64) and must return a boolean. Example: "value >= 900".

var Registry = []Definition{
{Key: "busBandwidthGBps", Unit: "GB/s", Description: "Bus bandwidth (from BandwidthMeasurement)"},
{Key: "algBandwidthGBps", Unit: "GB/s", Description: "Algorithm bandwidth (from BandwidthMeasurement)"},
{Key: "goodputRatio", Unit: "ratio (0-1)", Description: "Goodput ratio (from GoodputMeasurement)"},
{Key: "avgTFLOPsPerGPU", Unit: "TFLOPS", Description: "Average TFLOPS per GPU (from GoodputMeasurement)"},
{Key: "avgStepTimeSec", Unit: "seconds", Description: "Average step time (from GoodputMeasurement)"},
}
Registry lists all known threshold keys. Unknown keys are rejected by ValidateKeys.
Functions ¶
func Evaluate ¶
Evaluate compiles and evaluates a CEL expression with the measured value. Returns true if the threshold is satisfied (expression returns true), false if violated (expression returns false). Returns an error if the expression fails to compile or evaluate.
func ValidateKeys ¶
ValidateKeys returns any keys in thresholds that are not in the Registry.
Types ¶
type Definition ¶
