first contentful paint (FCP), Time to first byte (TTFB)

[fstekelenburg]

Allthough it's mentioned in RFE : CrUX metrics, and visible in details of the Contributors breakdown graph ((K) in below image), I can not pull the first contentful paint (FCP),  metric with the USQL, not use it in a custom chart. 
The Time to first byte (TTFB) can be used in a custom chart, but is not found in the USQL either?

If this is by design, are there plans to make this available or are there reason not to?

Hi @fstekelenburg ,

You are right, it seems that those two metrics do not appear on the structure for the user action table over USQL:
https://www.dynatrace.com/support/help/dynatrace-api/environment-api/user-sessions/user-session-stru...

It may be that both are not yet metrics exposed on the Metrics API v2, as I could not locate them there either.

I recommend opening a product suggestion with this request.

Hi Team,

You can find Time to First Byte on USQL as Response Start (useraction.responseStart)
