/**
 * ### Deriving SLIs and other metrics from a trace
 *
 * ℹ️ It is our recommendation that the primary way of creating duration metrics would be to derive them from data in the trace.
 *
 * Instead of the traditional approach of capturing isolated metrics imperatively in the code,
 * the **trace** model allows us the flexibility to define and compute any number of metrics from the **trace recording**.
 *
 * We can distinguish the following types of metrics:
 *
 * 1. **Duration of a Computed Span** — the time between any two **spans** that appeared in the **trace**. For example:
 *    1. _time between the user’s click on a ticket_ and _everything in the ticket page has fully rendered with content_ (duration of the entire operation)
 *    2. _time between the user’s click on a ticket_ and _the moment the first piece of the ticket UI was displayed_ (duration of a segment of the operation)
 *
 * 2. **Computed Values** — any numerical value derived from the **spans** or their attributes. For example:
 *    1. _The total number of times the log component re-rendered while loading the ticket_
 *    2. _The total number of requests made while loading the ticket_
 *    3. _The total number of iframe apps were initialized while loading the ticket_
