Metrics for Pull Request Reviews
The PR Review Trends page shows you metrics for GitHub Pull Request Reviews over time.
Review Trend Metrics
The following charts are available:
- Number of reviews submitted
- Time to respond to review requests
You can filter the “Number of reviews submitted” chart by review result
- Approved
- Commented
- Changes requested
- All
Results can be grouped by any combination of Repo, Team, User or Time Period.
See the Metrics Explorer section for how to set search and grouping parameters.


Note that the final section of both charts is shaded. This is because the query was run
part way through June, so the final time bucket only has partial data.
Click on any node in the chart to see exactly which PR Reviews contributed to that node.
