Change Failure Rate
Change failure rate gives the percentage of deployments which result in degraded service and subsequently require remediation (hotfix, rollback, patch, etc).
This metric is configurable under app.hatica.io/settings/dora (opens in a new tab) and currently supports either a PR label Regex or a PR title Regex to recognise PRs containing the fix for a recent failure
App inputs to this metric:
