Comparing Releases to Track Regressions
Use release comparison to identify regressions and improvements between deployments.
Release Comparison
From the release detail page, click Compare to see a side-by-side analysis against any previous release.
What's Compared
| Metric | What It Shows |
|---|---|
| Total logs | Volume change between releases |
| Error events | Whether errors increased or decreased |
| New issues | Error types that didn't exist in the previous release |
| Error rate | Percentage of logs that are errors |
| Warnings | Warning count change |
Reading the Comparison
- Green metrics = improvements (fewer errors, lower error rate)
- Red metrics = regressions (more errors, new issues introduced)
- Errors resolved = error groups that stopped occurring in the new release
- Errors introduced = new error groups first seen in this release
