Issue
In the Transaction Summary page, I found that there are many events in sampled events, but there are only a few events listed in Web Vitals page. What is the relationship between the two, and why are there so few events listed in Web Vitals?
Applies To
- Sentry Customers using Performance and Web Vitals
Symptoms
- Web Vitals view lists less transactions than Transaction Summary page.
Resolution
Web vitals are only collected on pageload transactions, but the full sampled event list also includes navigation transactions, which are much more frequent.
You can filter the samples list on the Transaction Summary page to remove the navigation transactions by adding transaction.op:pageload to the search bar.
