Hi all, I'm not sure if I'm missing something but I'm seeing a behaviour with the python client and multiprocess using gunicorn and flask I'm not sure if I'm missing something or there's a bug there.
When I hit the endpoint producing the prometheus text to be scrapped I'm seeing 2 versions for the same metrics with different help texts. I would expect to see only one metric (the multiprocess one). I thought I had something wrong in my setup so I tried it with e pretty simple project that I found here https://github.com/amitsaha/python-prometheus-demo/tree/master/flask_app_prometheus_multiprocessing (not my code). I hit a random url and then the `/metrics` endpoint You can see in the raw response down here we have 2 entries for each metric, with different `types` and `help` texts. In this example there really wasn't any processes but in the real example in prod we have several processes and we see the prometheus scraper `picks` a different value depending on the order of the response. Am I missing something or is there a bug there? The raw response was: <pre> % curl --location --request GET 'http://localhost:5000/metrics' # HELP request_latency_seconds Multiprocess metric # TYPE request_latency_seconds histogram request_latency_seconds_sum{app_name="webapp",endpoint="/metrics"} 0.00040912628173828125 request_latency_seconds_sum{app_name="webapp",endpoint="/"} 0.0001652240753173828 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.005"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.01"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.025"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.05"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.075"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.1"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.25"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="0.75"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="1.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="2.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="5.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="7.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="10.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/metrics",le="+Inf"} 1.0 request_latency_seconds_count{app_name="webapp",endpoint="/metrics"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.005"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.01"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.025"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.05"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.075"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.1"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.25"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="0.75"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="1.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="2.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="5.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="7.5"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="10.0"} 1.0 request_latency_seconds_bucket{app_name="webapp",endpoint="/",le="+Inf"} 1.0 request_latency_seconds_count{app_name="webapp",endpoint="/"} 1.0 #
