▶ http-perf -h
Usage of http-perf:
  -chartpath string

  -count int
        how many times shoud be measured. If used, time flag will be ignored
  -json
        creates a json file with keys requests, timeTotalNS, timePerRequestMS, errorCount(non 200 http status), statusCounts(object, httpstatuscode as key, count as value)
  -jsonpath string
        filepath for json file (default "perf.json")
  -n int
        amount of goroutines beeing used (default 100)
  -nochart

  -time int

  -url string
