What metrics can be collected in CI/CD?

In CI/CD, the following metrics can be collected to assess the quality and efficiency of processes:

• Percentage of successful builds and deployments — indicates pipeline stability.
• Build and test execution time — helps optimize delivery speed.
• Test coverage — percentage of code tested.
• Number of bugs found during testing — code quality before release.
• Frequency and reasons for build failures — to identify problematic changes.
• Response time and performance after deployment (if integrated with monitoring).
• Rollback time — how quickly a stable version can be restored.
• Statistics on test types (unit, integration, e2e) — testing balance.

Collecting such metrics allows for informed decision-making to improve software development and delivery processes.
