TTFB in USQL

[chris_palmer]

It would be useful to have TTFB available as an option for USQL. All other Core Web Vitals are available but not this one.

@chris_palmer,

In a user action you have multiple TTFB, one for each request.

There is a variable serverTime that gives you that information though.

Thank you for the reply. I'm looking to run a query like this only with TTFB rather than LCP:

I spoke to customer support regarding this and they suggested Response Time as an alternative but we didn't feel this was an accurate reflection of TTFB. They also suggested asking regarding TTFB here.

select serverTime from useraction

will get you what you want. Just adapt it to your query.
