Avg. page load time

Which tracking API parameter corresponds to “Avg. page load time”? (see screenshot)
Reading the manual I was under the impression it would be gt_ms but despite sending it, the column stays empty.

Related question, where does the info sent via gt_ms go? I can’t seem to find it anywhere in the analytics back-end.

For context, I’m writing my own tracker from scratch.


I am not sure if Matomo 4 isn’t using the data from the new Page Performance info and the new API parameters for it (https://developer.matomo.org/api-reference/tracking-api) instead.

Maybe @SteveG can confirm?

The Average Page load time was deprecated as of Matomo 4 in favor of the new page performance metrics. It won’t show any number for newer reports, but is still shown in some reports so it’s possible to view numbers for older data.

This is really helpful and meaningful. Here is my site miscof.com also causing this issue.
