List a component's effective metrics

GET

/components/{name}/metrics

const url = 'https://example.com/api/v1/components/example/metrics';
const options = {method: 'GET'};

try {
  const response = await fetch(url, options);
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error(error);
}

curl --request GET \
  --url https://example.com/api/v1/components/example/metrics

Every metric the component’s product declares, resolved to the series’ latest observed or calculated sample or the contract default until one arrives (is_sampled marks a live series), plus any metric sampled directly on the component (from_contract false). Gated by component:read; an out-of-scope component is a non-disclosing 404.
