sanic multi worker metrics are not populated

[alexterman]

I am trying to add metrics to sanic application.
When running 1 worker everything looks fine, but when configuring more workers no metrics being sent to carbon.

import random
import time

from sanic import Sanic
from sanic.response import json

from pyformance import MetricsRegistry
from pyformance.reporters.carbon_reporter import CarbonReporter

registry = MetricsRegistry()
__reporter__ = CarbonReporter(registry=registry,
                              reporting_interval=10,
                              prefix='sanic',
                              server='localhost',
                              port=2003)
__reporter__.start()
app = Sanic()

@app.route("/api/v1/foo", methods=["POST"])
def foo(request):

    timer = registry.timer(".foo")
    with timer.time():
        time.sleep(random.randint(1, 2))
        return json({"status": True})

if __name__ == "__main__":
    app.run(host='0.0.0.0', port=20100, workers=1, access_log=False, debug=False)

Sorry, no idea what Sanic is. Could this be because of threading or forking?

@omergertel thanks for the answer, is pyformance should be used in a single-threaded environment?
