function monitorEventLoopDelay
Usage in Deno
```typescript import { monitorEventLoopDelay } from "node:node__perf_hooks.d.ts"; ```
monitorEventLoopDelay(options?: EventLoopMonitorOptions): IntervalHistogram

Creates an `IntervalHistogram` object that samples and reports the event loop
delay over time. The delays will be reported in nanoseconds.
Using a timer to detect approximate event loop delay works because the
execution of timers is tied specifically to the lifecycle of the libuv
event loop. That is, a delay in the loop will cause a delay in the execution
of the timer, and those delays are specifically what this API is intended to
detect.
```js
import { monitorEventLoopDelay } from 'node:perf_hooks';
const h = monitorEventLoopDelay({ resolution: 20 });
h.enable();
// Do something.
h.disable();
console.log(h.min);
console.log(h.max);
console.log(h.mean);
console.log(h.stddev);
console.log(h.percentiles);
console.log(h.percentile(50));
console.log(h.percentile(99));
```
