Action Summary

The Build Process Watcher GitHub Action monitors memory usage of Java/Kotlin build processes (e.g., Gradle Daemon, Kotlin Compile Daemon) during CI workflows. It automates the tracking of heap and RSS memory usage, generates visualizations like charts, and provides real-time dashboards for performance analysis. This action helps developers optimize build performance by identifying memory bottlenecks and analyzing Garbage Collection metrics.

🐛 Fixes

disable_summary_output in local mode (#40)

🗑️ Removed

  • collect_gc input (GC is always enabled)
  • Staging deployment workflows
