+> This parameter only works when running the helm chart locally. When installing the helm chart using the remote repository it is not possible to include "external" scrape config files into the helm structure. This is also true when the chart is used as a subchart, and the scrape config files exists in the parent chart. Ref. [helm docs](https://helm.sh/docs/chart_template_guide/accessing_files/)
 
 By default, the daemonset collector will load in the daemon_scrape_configs.yaml file which collects prometheus metrics from applications on the same node that have the prometheus.io/scrape=true annotation, kubernetes node metrics, and cadvisor metrics. Users can disable this by settings collectors.daemon.scrape_configs_file: "" OR they can provide their own promethues scrape config file for the daemonset by supplying collectors.daemon.scrape_configs_file: "<your-file>.yaml"
