performanceNodeTiming.uvMetricsInfo
- 返回值: <Object>
这是 uv_metrics_info 函数的封装。它返回当前的一组事件循环指标。
【This is a wrapper to the uv_metrics_info function.
It returns the current set of event loop metrics.】
建议在使用 setImmediate 安排执行的函数中使用此属性,以避免在完成当前循环迭代期间安排的所有操作之前收集指标。
【It is recommended to use this property inside a function whose execution was
scheduled using setImmediate to avoid collecting metrics before finishing all
operations scheduled during the current loop iteration.】
const { performance } = require('node:perf_hooks');
setImmediate(() => {
console.log(performance.nodeTiming.uvMetricsInfo);
});import { performance } from 'node:perf_hooks';
setImmediate(() => {
console.log(performance.nodeTiming.uvMetricsInfo);
});
