<section>
<p>Metric instance configuration overrides.
The metric value and the metric type are optional and permit changing the
reported value for an existing metric.
The standard metrics are optimized and reported through a &ldquo;fast-path&rdquo;.
The customizations allow full configurability, at the cost of a &ldquo;slower&rdquo;
path.</p>
