 ### Minimal ingestion for default OFF targets
 The following are metrics that are allow-listed with `minimalingestionprofile=true` for default OFF targets. These metrics are not collected by default as these targets are not scraped by default (due to being OFF by default). You can turn ON scraping for these targets using `default-scrape-settings-enabled.<target-name>=true`' using [ama-metrics-settings-configmap](https://aka.ms/azureprometheus-addon-settings-configmap) under `default-scrape-settings-enabled` section.
