JProfiler merupakan software komersial dengan opsi evaluasi, bukan freeware tanpa batas.

Software Information

What Is EJ Technologies JProfiler?

JProfiler adalah Java profiling tool yang digunakan untuk memeriksa bagaimana aplikasi Java menggunakan sumber daya sistem saat berjalan. Developer dapat melihat metode yang paling banyak menggunakan CPU, objek yang memenuhi heap memory, aktivitas thread, serta operasi database dan jaringan yang membutuhkan waktu lama.

Software ini cocok untuk developer Java, software engineer, tim backend, dan administrator aplikasi yang perlu melakukan troubleshooting performa. JProfiler dapat digunakan untuk profiling aplikasi lokal maupun JVM jarak jauh, termasuk lingkungan berbasis Docker dan Kubernetes yang didukung.

Key Features of EJ Technologies JProfiler

– CPU Profiling: Analisis penggunaan CPU untuk menemukan metode dan bagian kode yang membutuhkan waktu pemrosesan paling besar. Call tree, hot spots, dan flame graphs membantu mempersempit sumber masalah performa.

– Memory Profiling: Pantau alokasi objek, penggunaan heap, dan aktivitas garbage collection. Fitur ini membantu menemukan pola penggunaan memori yang tidak efisien serta potensi memory leak.

– Heap Walker: Periksa objek yang tersimpan di heap dan telusuri hubungan antarobjek. Kamu dapat menganalisis reference chains, jalur menuju GC roots, dominator chains, dan objek berukuran besar.

– Thread Profiling: Pantau aktivitas thread, status thread, dan penggunaan monitor. Fitur ini berguna untuk menyelidiki thread contention, deadlock, serta masalah sinkronisasi.

– Database Profiling: Analisis aktivitas JDBC dan JPA/Hibernate untuk menemukan query database yang lambat atau terlalu sering dijalankan. Data yang ditampilkan membantu developer memahami pengaruh operasi database terhadap performa aplikasi.

– HTTP and Web Profiling: Pantau permintaan HTTP dan aktivitas server yang didukung. Informasi durasi, status, error, serta timeout dapat membantu menemukan masalah pada komunikasi aplikasi.

– AI Application Profiling: AI probe membantu memantau interaksi aplikasi dengan model bahasa besar melalui framework yang didukung, termasuk LangChain4j dan Spring AI.

– MCP Server Integration: JProfiler menyediakan Model Context Protocol server agar AI coding agent dapat mengakses informasi profiling dan membantu menganalisis masalah JVM melalui fitur yang didukung.

– Remote Profiling: Hubungkan JProfiler ke JVM yang berjalan di komputer atau server lain. Dukungan SSH dan remote attach membantu developer melakukan investigasi tanpa harus menjalankan aplikasi secara lokal.

– Docker and Kubernetes Support: Profiling dapat dilakukan pada JVM di lingkungan container yang kompatibel. JProfiler membantu menemukan dan memilih proses yang ingin dianalisis.

– JFR Recording Analysis: Buka dan analisis rekaman Java Flight Recorder untuk memeriksa event JVM serta aktivitas aplikasi dalam periode tertentu.

– IDE Integration: Integrasikan JProfiler dengan lingkungan pengembangan yang didukung agar proses menjalankan dan menganalisis aplikasi Java menjadi lebih praktis.

– Offline Profiling: Atur proses profiling melalui parameter agent atau command-line tools, termasuk konfigurasi perekaman otomatis dan penyimpanan snapshot.

– Performance Snapshots: Simpan hasil profiling untuk dianalisis kemudian atau dibandingkan dengan hasil pengukuran lainnya.

– Cross-Platform Support: Gunakan JProfiler di Windows, macOS, dan Linux dengan paket instalasi yang disediakan untuk masing-masing platform.
