trace-cmd
Trace-cmd is a powerful command line tool used for tracing and analyzing Linux system events. It is designed to capture system calls, signals, and other events occurring in the Linux kernel.
This tool utilizes the Linux kernel's tracing infrastructure and provides a flexible and efficient way to trace system activities. It offers various features like taking precise timing measurements, recording system call arguments, and capturing process information.
Trace-cmd provides different output formats such as text, CSV, and JSON, making it easy to analyze and process the generated trace data. The captured traces can be visualized using graphical tools like KernelShark, which is a complementary tool for Trace-cmd.
One key advantage of using Trace-cmd is its low overhead impact on the system, allowing tracing to be enabled for extended periods without significant performance degradation. It can be used for performance analysis, debugging, and profiling various aspects of the Linux kernel and user-space applications.
The tool is typically integrated with other performance analysis tools like perf, ftrace, and eBPF to get a more comprehensive understanding of system behaviors. It is widely used by system administrators, developers, and performance engineers to diagnose and optimize Linux-based systems.
Trace-cmd has comprehensive documentation, command examples, and support from the Linux community, making it a valuable tool for anyone working with Linux system tracing and performance analysis.
