Class IntervalTracker

avg

• get avg(): number

  Returns number

elapsed

• get elapsed(): number

  Returns the elapsed time, in milliseconds since the instance was created

  Returns number

initial

• get initial(): undefined | V

  Returns the initial value, or undefined

  Returns undefined | V

last

• get last(): undefined | V

  Returns undefined | V

size

• get size(): number

  Returns number of recorded values (this can include the initial value)

  Returns number

difference

• difference(): undefined | number

  Difference between last value and initial. Eg. if last value was 10 and initial value was 5, 5 is returned (10 - 5) If either of those is missing, undefined is returned

  Returns undefined | number

filterData

• filterData(rawValues: number[]): TimestampedPrimitive<number>[]

  Tracks a value

  Parameters

  • rawValues: number[]

  Returns TimestampedPrimitive<number>[]

getMinMaxAvg

• getMinMaxAvg(): { avg: number; max: number; min: number }

  Returns { avg: number; max: number; min: number }

onReset

• onReset(): void

  Returns void

onTrimmed

• onTrimmed(reason: TrimReason): void

  When trimmed, recomputes to set total/min/max to be based on current values.

  Parameters

  • reason: TrimReason

  Returns void

relativeDifference

• relativeDifference(): undefined | number

  Relative difference between last value and initial. Eg if last value was 10 and initial value was 5, 2 is returned (200%)

  Returns undefined | number

reset

• reset(): void

  Reset tracker

  Returns void

seen

• seen(...p: number[]): NumberTrackerResults

  Adds a value, returning computed result.

  At this point, we check if the buffer is larger than resetAfterSamples. If so, reset() is called. If not, we check sampleLimit. If the buffer is twice as large as sample limit, trimStore() is called to take it down to sample limit, and onTrimmed() is called.

  Parameters

  • ...p: number[]

  Returns NumberTrackerResults

trimStore

• trimStore(limit: number): number

  Reduces size of value store to limit. Returns number of remaining items

  Parameters

  • limit: number

  Returns number
