Как решить проблему ImportError: cannot import name 'start_http_server' from 'prometheus_client'?

Question

[Николай Бараненко]

Здравствуйте.

Попробовал написать клиент для prometheus

#!/usr/local/bin/python
# coding: utf-8
# import sys
# from pprint import pprint as p
# p(sys.path)

from prometheus_client import start_http_server, Summary
import random
import time

# Create a metric to track time spent and requests made.
REQUEST_TIME = Summary('request_processing_seconds', 'Time spent processing request')

# Decorate function with metric.
@REQUEST_TIME.time()
def process_request(t):
    """A dummy function that takes some time."""
    time.sleep(t)

if __name__ == '__main__':

    # Start up the server to expose the metrics.
    start_http_server(8000)
    # Generate some requests.
    while True:
        process_request(random.random())
