Hi! For the past few days I have noticed that all of my site’s web vitals are not showing anymore, i.e., Largest Contentful Paint (LCP); Interaction to Next Paint (INP); and Cumulative Layout Shift (CLS). Please help.
Hi Erick!
It seems like you’re current date period is set to Today
. We calculate all of the metrics with a 1 day delay so there won’t be any data. This is something we need to address in the UI.
In the meantime, you can click on that button and select Last 7 days
or Last 30 days
, both of which should work fine
Cheers!
To be precise, I need help to display the usual things I report to my client about LCP, INP and CLS. Prior to May 10, I have these pieces of info displayed in the area I have highlighted with red. LCP in seconds (s), INP in milliseconds (ms) and CLS in decimal value. I want to keep it that way not P75.
Does anyone know how I can revert to this? Thanks in advance.
Oh yes, my bad. I toggled for today instead of 7 days or 30 days. Please see my latest reply. As I need to display these values like before, i.e., not in P75.
Ah alright. We’ve always been showing the 75th percentile values (or P75 for short) on this screen. You can also click on each one of them to get more details. They may be a bit different since last week though.
We released new web performance reports which replaced the old ones. They are now way more powerful and allow inspecting metrics for specific: page types, URLs, target elements, and more.
This involves a lot of data, so we had to introduce a 10% sampling in the initial version. This is where the differences may be coming from from the previous view. Still, the source for those calculations are the same real user measurements as before.
We are also working on optimising the data pipeline to get rid of the sampling entirely.
Hmm… Okay… Yeah I know what P75 means — it’s the third quartile.
Were these changes included in https://changelog.shopify.com/ ?
It’s just that these changes caught me off guard.
Yeah, percentiles are quite commonly used in the site speed realm but I wanted other people that may find this thread to understand what we mean as well
Sorry for this surprise, this feature will be officially announced as a part of Summer Editions.
