Cloud Profiler adalah profiler statistik dengan overhead rendah yang terus mengumpulkan informasi penggunaan CPU dan alokasi memori dari aplikasi produksi Anda. Cloud Profiler mengatribusikan informasi tersebut ke kode sumber yang menghasilkannya, membantu Anda mengidentifikasi bagian aplikasi yang paling banyak menggunakan resource, dan menunjukkan karakteristik performa aplikasi Anda. Untuk ringkasan mendetail, lihat
Konsep profiling dalam dokumentasi
Cloud Profiler.
Untuk merekam data pembuatan profil untuk runtime Java terbaru yang didukung, lihat
Membuat profil aplikasi Java.

It attributes that information to the source code\nthat generated it, helping you identify the parts of your application that are\nconsuming the most resources, and otherwise illuminating your applications\nperformance characteristics. For a detailed overview, see\n[Profiling concepts](/profiler/docs/concepts-profiling) in the Cloud Profiler\ndocumentation.\n\nTo capture profiling data for the latest supported Java runtime, see\n[Profiling Java applications](/profiler/docs/profiling-java)."]]
