Docs:- Exporter metrics scrapped through agentless collector

[praneethreddytekula-amazon]

Hi, in a recent demo to a customer on agentless prometheus collector on EKS with destination as AMP. I found that, default scrape configuration only scrapes few out of the box metrics like cadvisor, kubeproxy etc., metrics.

To push metrics of an exporter like node-exporter, agentless collector needs additional scraper configuration lines as below to the default configuration.

Today, this isn't stated anywhere on our documentation or blog posts. For persona's that aren't experts on EKS or prometheus. It takes time to figure that out, by talking to an expert.

• Launch blog post, shows node exporter metric as a screenshot but doesn't mention anywhere about the additional configuration required:- https://aws.amazon.com/blogs/aws/amazon-managed-service-for-prometheus-collector-provides-agentless-metric-collection-for-amazon-eks/
