Issue
I have noticed that the span count in my Explore > Traces tab is different compared to the amount of spans I see in my Stats tab. Why is that?
Applies To
All SaaS Customers and Self-Hosted Users
Tracing
Symptoms
Traces sample rate is less than 1 but above 0.
Resolution
Results in the Explore > Traces page are extrapolated based on client side sample rates. The Stats page shows raw usage to track consumption.
This is further explained here. If for example you have a traces sample rate of about 1 in 4M, this would also explain why your estimated count is calculated in increments of 4M too. However, your stats page is the source of truth for how many spans actually make it to Sentry.
