Wrong statistic of total request count

[liming-gd]

Description of issue / feature request

Locust told me 249 requests had been made, but I got 327 records from service access log.

Expected behavior

I think locust should report that the completed requests is 327, but not 249.

Environment settings (for bug reports)

• OS: Ubuntu 14.04.5 LTS
• Python version: Python 2.7.6
• Locust version: 0.8.1

Steps to reproduce (for bug reports)

Just run the following command in shell:

locust -H http://10.44.147.237:8024 -f locustfile.py --no-web -c 50 -r 10 -n 200

lucustfile.py

# -*- coding: utf-8 -*-

from __future__ import absolute_import

import locust


class PerformanceTaskSet(locust.TaskSet):

    @locust.task(weight=1)
    def apply_resources(self):
        self.client.put(
            '/accounts/xxxx/projects/integration-test/resource_apply/',
            json={'cpu': 8, 'memory': 16}
        )


class PerformanceLocust(locust.HttpLocust):

    task_set = PerformanceTaskSet

    min_wait = 100
    max_wait = 1000

Without setting not to reset stats, Locust will make requests while scaling up the users and then reset stats.

In 0.8.1 that is --no-reset-stats but will change in 0.9.0 #674

[gwshawsh]

I have the same problem... It doesn't work with 0.9.0.

[cgoldberg]

@gwshawsh what doesn't work?

[gwshawsh]

@cgoldberg Locust shows 6283 requests , but I got 6329 records from access log. V0.9.0 without '--reset-stats' like this 'locust -f ./sale_test.py --no-web -c 800 -r 100 -t 60s' .

[cgoldberg]

are you actually seeing stats refresh after hatch, or do you just see a discrepancy in results and are guessing that is the cause?

could you be running an older version older than 0.9.0?

I'm running 0.11.0 version and I have the exact same problem.
