metric

const (
	AggregateFunctionAvg = "_agg_avg"
	AggregateFunctionMax = "_agg_max"
	AggregateFunctionMin = "_agg_min"
	AggregateFunctionP99 = "_agg_p99"
	AggregateFunctionP90 = "_agg_p90"
)

aggregated functions that'd supported by katalyst now, and client should add those as suffix in metric-name when referring to kcmas. for instance, `pod_cpu_load_1min_agg_max` means to return a single metric item to represent the max value of all collected items, and we will put the corresponding time-window in response.
