Inspect experiment exposure logs on the Health tab
GrowthBook 5.2 adds exposure logs to a new Diagnostics section on an experiment's Health tab. You can filter individual exposure records and see who entered the experiment and which variation they saw, without writing a query.
From aggregate counts to individual rows
The Health tab charts experiment traffic and checks variation balance using aggregate counts. When one of those numbers looks wrong, the next question is often about specific records. Exposure logs show the rows behind the experiment's assignment data, so you can trace a data quality question to individual events.
What you can do
- Filter the log to one variation, a user ID, or a dimension value.
- Expand any row to see the full exposure record as JSON.
- Page through the results without leaving the Health tab.
- Check a targeting question directly, such as whether exposures appear under a dimension value the experiment wasn't meant to reach.
Getting started
Open an experiment and select its Health tab. If the Health tab isn't enabled yet, enabling it runs one additional query per experiment analysis and requires permission to run queries. The exposure logs appear below the traffic chart. Filter to one variation, then expand a row to check the full record. Log in to GrowthBook to try it on one of your experiments.
