How to write locust test result api to file

Question

I call the test through the API,

locust -f locustfile.py --host=http://localhost --no-web  --hatch-rate=20 --clients=10000

and got the result

 Name                                                          # reqs      # fails     Avg     Min     Max  |  Median   req/s
--------------------------------------------------------------------------------------------------------------------------------------------
 POST 8000/queries.json                                           137     0(0.00%)       5       2      23  |       5   11.00

--------------------------------------------------------------------------------------------------------------------------------------------
 Total                                                            708     0(0.00%)    

I would like to write this result to a file. Can anyone help me with this?

Below is the code in python

@task(1)
def test_topview(self):
    post_data_topview = """{ "category": "321",   "num": 20,   "genderCat" : ["23"] }"""
    with self.client.request(method="POST", url="http://192.168.1.107:8001/queries.json", headers= {"Content-Type" : "application/json"}, data = post_data_topview, catch_response = True ) as response:
        if not matched(response.content) :
            response.failure("No content")

Many thanks.

Another option, until the statsfile parameter is available, will redirect stderr to the output file, which, apparently, is where the statistics are recorded:

 locust -f locustfile.py --host=http://example.com --no-web --clients=20  --hatch-rate=20 --num-request=1000  --only-summary  > locust.log   2>&1

UPDATE

Saving the csv file with the option is --csvadded using release . Thus, you can run the following command to save the test result as foo_requests.csvandfoo_distribution.csv

locust -f locustfile.py --host=http://localhost --no-web  --hatch-rate=20 --clients=10000 --only-summary --csv=foo
