elastic 의 timelion 이라는 도구에서는 위와 같이 line 그래프에 커서를 올리면 동일한 시간대에 다른 그래프에도 세로 줄이 생깁니다.
어떤 이슈가 발생했을 때 동일 시점에 다른 항목들이 어떤 상태인지를 쉽게 볼 수 있는 방법인 듯 해요.

기능 추가 검토 요청 드립니다. ^^;

I'm seeing more metrics than documented at https://github.com/axemclion/browser-perf/wiki/Metrics. I'm guessing some of them are newer additions in timeline. It would be great to document more of them.

Here's an example output of my script that compares 2 versions of a page:

AnalyzeTask 7.276   7.947
AnalyzeTask_avg 0.01144025157   0.01028072445
AnalyzeTask_count   636 773
AnalyzeTask_max 0.

'http-outbound'/'https-outbound' events return undefined response statusCode if client uses request, request-promise or any other http libraries that do not use callback when making http.request. You mention this in the code comment (https://github.com/RuntimeTools/appmetrics/blob/master/probes/http-outbound-probe.js#L91), but there is no explanation on work-around for popular http libraries

Is your feature request related to a problem? Please describe.

I am unable to add instrumentation for Global Objects in the agent in a way that is described here. There are few methods that I needed to instrument like eval(), setTimeout() etc.
(PS: I don't know if I am approaching this right)

**Describe the solution you'd li

前端性能指标的监控,采集以及上报。用于测量第一个dom生成的时间(FP/FCP/LCP)、用户最早可操作时间(fid|tti)和组件的生命周期性能,,网络状况以及资源大小等等。向监控后台报告实际用户测量值。
