Empty stats on get aggregated stats

[drgarcia1986]

I'm trying to save the test results to a file, but the result is saved with empty values, am I doing something wrong? I am using the following event:

def on_quitting():
    requests_result = RequestStats().aggregated_stats()
    with open('load_tests.json', 'w') as f:
        f.write(str(requests_result.serialize()))


events.quitting += on_quitting

And I'm execultando the locust as follows:

locust -f locust_script.py --no-web -c 10 -r 5 -n 50 -H http://localhost:5000 --only-summary

The console is being presented the following result:

but in the file:

{'num_reqs_per_sec': {}, 'response_times': {}, 'start_time': 1421713788.737998, 'min_response_time': None, 'num_failures': 0, 'num_requests': 0, 'name': 'Total', 'total_response_time': 0, 'max_response_time': 0, 'total_content_length': 0, 'last_request_timestamp': 1421713788, 'method': None}

Solution:

from locust.stats import global_stats


def on_quitting():
    requests_result = global_stats.aggregated_stats()
    with open('load_tests.json', 'w') as f:
        f.write(str(requests_result.serialize()))

I have this same issue now, but I think my issue is to do with the way I'm quitting my Locusts.

How did you quit the Locust that you ran from the console?
