Overview

Diagnosis and Debugging is a sub-tool of the Kunpeng Hyper Tuner.

The Diagnosis and Debugging is a performance analysis tool for Kunpeng-powered servers. It provides memory leak diagnosis (including memory release failure and abnormal memory release), memory usage analysis and display, as well as out of memory (OOM) diagnosis capabilities. Use this tool to identify memory usage issues in source code and improve application reliability.

The Diagnosis and Debugging provides the following features:

• Memory leak diagnosis: Analyzes the memory leaks (including memory release failure and abnormal memory release) of applications to obtain the specific leak information and associate the call stacks and source code.
• Memory usage analysis: Traces the memory consumption of the system layer, application layer (invoking memory application functions), allocator layer, and memory map layer in real time when applications are running.
• OOM diagnosis: Analyzes the process memory status, system memory status, and call stack information when OOM occurs.
