Help Needed for metric type summary

I have two questions

1. Is there a way to store average latency time based on the histogram flask_http_request_duration_seconds_sum and flask_http_request_duration_seconds_count as another metric?

2. What is the best way to pass r.status_code if you do not use @app.route to instantiate? I am using BluePrint and Flask_restful to register and instantiate separately as in

Following your example on creating a summary

@app.route('/status/<int:status>')
@metrics.summary('requests_by_status', 'Request latencies by status', labels={'status': lambda r: r.status_code})
        def echo_status(status):
            return 'Status: %s' % status, status

from flask import Blueprint
from flask_restful import  Resource

api_v1 = Blueprint('api_v1', __name__, url_prefix='/api/v1')
rest_api_v1 = Api(api_v1, errors=errors)


def add_resource(resource, route, endpoint=None, defaults=None):
    """Add a resource for both trailing slash and no trailing slash to prevent redirects."""
    slashless = route.rstrip('/')
    endpoint = endpoint or resource.__name__.lower()
    defaults = defaults or {}

    # resources without slashes
    rest_api_v1.add_resource(resource,
                             slashless,
                             endpoint=endpoint + '__slashless',
                             defaults=defaults)

class Test(Resource):
    status = 200

    @staticmethod
    @metrics.summary('dummy_test', 'Test Request latencies by status',
                     labels={'dummy_test': lambda r: ???})
    def get():
        try:
            time.sleep(random.randint(0, 5))
            if random.choice([True, False]):
                return 'OK', 200
            else:
                return 'Not OK', 400
        except Exception as e:
            logger.error('%r' % e)

add_resource(Test, '/test', endpoint='test')

Thank you. I will give it a try on 0.8.2

I think I managed to get it working for your use case. It’s running through Travis now, and should be available in 0.8.2 very soon. Thanks again for the report!
