title: Stop scraping of default metric in prometheus_client in python
body: <p>I am integrating prometheus to scrape custom metrics from my application. However I am receiving lots of unwanted metric which are enabled by default. Is there a way to disable these metric, so as to collect only the custom metrics I want.</p>
