Duplicated timeseries in CollectorRegistry

[Barry Al-Jawari]

Im currently facing an issue where I do get an error that is saying:

   ` ValueError: Duplicated timeseries in CollectorRegistry: {'scraper_request_count_created', 'scraper_request_count_total', 'scraper_request_count'}`

I have two scripts which we can call file1.py and file2.py

**file1.py**:

```py

import time

import requests

from lib.prometheus import REQUEST_COUNT

    

def from_page(url):

   while True:

     with requests.get(url) as rep:

         REQUEST_COUNT().labels(store="stackoverflow", http_status=rep.status_code).inc()

         print("Response: ", rep.status_code)

         time.sleep(60)

if __name__ == '__main__':

   from_page("https://stackoverflow.com")

```

**file2.py**

```py

import time

import requests

from lib.prometheus import REQUEST_COUNT

    

def from_page(url):

   while True:

     with requests.get(url) as rep:

         REQUEST_COUNT().labels(store="google", http_status=rep.status_code).inc()

         print("Response: ", rep.status_code)

         time.sleep(60)

if __name__ == '__main__':

   from_page("https://google.com")

```

As you can see they both call the `lib.prometheus import REQUEST_COUNT` which is:

```py

    from prometheus_client import Counter, CollectorRegistry

    

    registery = CollectorRegistry()

    

    def REQUEST_COUNT():

        return Counter(

            namespace="scraper",

            name="request_count",

            documentation="Count the total requests",

            labelnames=['store', 'http_status'],

            registry=registery

        )

```

The problem is that if I run this script simultaneously then I will get the error `ValueError: Duplicated timeseries in CollectorRegistry: {'scraper_request_count_created', 'scraper_request_count_total', 'scraper_request_count'}` and I wonder what can I do be able to push the data even if its in duplicated timeseries?

Hey Barry,

I'm no expert, but I would think you are somehow implicitly using a global CollectorRegistry object in that code? 

Anyway, I would recommend raising this issue with prometheus/client_python repo who are the experts.

Best,

Ian
