Using prometheus client python

[vjanar...@gmail.com]

How often metrics will be cleaned for example if we running the flask framework in docker. I already implemented metrics in the path /metrics and it's running more than 24hrs and still /metrics is not cleared in docker. Is is it storing it some location and am afraid that it will take more memory. Thanks in advance

 https://www.robustperception.io/memory-usage-of-prometheus-client-libraries explains the memory usage, you shouldn't need to worry about it.

Thanks for the response. I think its storing the value each time. Here is the sample. check the dark line in below response. That request is health check is make request for every 60s it will take 2 request . so now there is 1600 request
