updating /stats/request responses via a flag

[bijancot]

Hi guys just wondering about /stats/requests url that from https://github.com/locustio/locust/blob/master/locust/stats.py module. can we add more responses in the json responses just using a flag instead of updating this responses

        return {
            "method": escape(self.method or "") if escape_string_values else self.method,
            "name": escape(self.name) if escape_string_values else self.name,
            "safe_name": escape(self.name, quote=False),
            "num_requests": self.num_requests,
            "num_failures": self.num_failures,
            "avg_response_time": self.avg_response_time,
            "min_response_time": 0 if self.min_response_time is None else proper_round(self.min_response_time),
            "max_response_time": proper_round(self.max_response_time),
            "current_rps": self.current_rps,
            "current_fail_per_sec": self.current_fail_per_sec,
            "median_response_time": self.median_response_time,
            **response_time_percentiles,
            "avg_content_length": self.avg_content_length,
        }

since in that module also a dict StatsEntryDict exist?

Thankyou! i also post it in slack please let me know if is it not allowed to make duplicate discussion

Hi! I'm sorry, but I don't really understand your question. What is your end goal, what have you tried, and why is that not working?

Hi @cyberw thank you for the responses. And i'am sorry for the confusion. So it's working indeed but i want to change the responses of /stats/requests from :

{
  "current_response_time_percentiles": {
    "response_time_percentile_0.95": null
  },
  "errors": [],
  "fail_ratio": 0.0,
  "state": "ready",
  "stats": [
    {
      "avg_content_length": 0,
      "avg_response_time": 0.0,
      "current_fail_per_sec": 0,
      "current_rps": 0,
      "max_response_time": 0.0,
      "median_response_time": 0,
      "method": null,
      "min_response_time": 0,
      "name": "Aggregated",
      "num_failures": 0,
      "num_requests": 0,
      "response_time_percentile_0.95": 0,
      "response_time_percentile_0.99": 0,
      "safe_name": "Aggregated"
    }
  ],
  "total_avg_response_time": 0.0,
  "total_fail_per_sec": 0,
  "total_rps": 0,
  "user_count": 0
}

to add more results like

{
  "current_response_time_percentiles": {
    "response_time_percentile_0.95": null
  },
  "errors": [],
  "fail_ratio": 0.0,
  "state": "ready",
  "stats": [
    {
      "avg_content_length": 0,
      "avg_response_time": 0.0,
      "current_fail_per_sec": 0,
      "current_rps": 0,
      "max_response_time": 0.0,
      "median_response_time": 0,
      "method": null,
      "min_response_time": 0,
      "name": "Aggregated",
      "num_failures": 0,
      "num_requests": 0,
      "response_time_percentile_0.95": 0,
      "response_time_percentile_0.99": 0,
      "safe_name": "Aggregated",
      "last_request_timestamp": float, 
      "start_time": float
    }
  ],
  "total_avg_response_time": 0.0,
  "total_fail_per_sec": 0,
  "total_rps": 0,
  "user_count": 0
}

i just want to modify the responses to add start_time and last_request_timestamp to /stats/request responses. So is there any way to modify these response by default by using some flags maybe since it's already mentioned in the struct that mentioned here https://github.com/locustio/locust/blob/master/locust/stats.py#L64-L76 ?

Thank you so much!
Best regards

Hi @bijancot, did you get an answer to your question yet? Perhaps you could provide some more information on your use case? If you want to record the timestamps for when the tests have started / ended, perhaps the event hooks would suit your use case - particularly test_start and test_stop?
