Node.js tracing.disable()用法及代码示例

tracing.disable()

禁用此 Tracing 对象。

只有其他启用的Tracing 对象未涵盖且未由--trace-event-categories 标志指定的跟踪事件类别将被禁用。

const trace_events = require('node:trace_events');
const t1 = trace_events.createTracing({ categories: ['node', 'v8'] });
const t2 = trace_events.createTracing({ categories: ['node.perf', 'node'] });
t1.enable();
t2.enable();

// Prints 'node,node.perf,v8'
console.log(trace_events.getEnabledCategories());

t2.disable(); // Will only disable emission of the 'node.perf' category

// Prints 'node,v8'
console.log(trace_events.getEnabledCategories());
