What logs and metrics are most useful for Cloud-native buildpacks?

Cloud-native buildpacks enable developers to transform application source code into container images. To ensure optimal performance and traceability, it's crucial to monitor specific logs and metrics associated with buildpacks.

Essential Logs and Metrics

  • Build Logs: Capture detailed logs during the build process to identify issues and understand the build's lifecycle.
  • Dependency Resolution Metrics: Monitor the time taken for dependency resolutions to identify bottlenecks.
  • Container Image Size: Keep track of the final image size to ensure efficient deployments.
  • Build Time: Measure the total time taken to build the application, facilitating optimization.
  • Failure Rates: Track the rate of build failures to quickly address recurring issues.

Example of Log Output

// Sample log entry during build [INFO] 2023-10-01T12:34:56Z Building application... [INFO] 2023-10-01T12:35:00Z Resolved dependencies in 5 seconds. [INFO] 2023-10-01T12:35:10Z Creating container image of size 150MB. [ERROR] 2023-10-01T12:35:20Z Build failed due to missing library XYZ.
