perf Alternatives
perf is described as 'Performance analyzing tool in Linux, available from Linux kernel version 2.6.31 under tools/perf, and is frequently updated and enhanced. It is capable of lightweight profiling, supports hardware performance counters, tracepoints, software performance counters (e.g' and is an app in the development category. There are eight alternatives to perf for Linux, BSD, FreeBSD, Mac and Solaris. The best perf alternative is ftrace, which is both free and Open Source. Other great apps like perf are Kcachegrind, strace, DTrace and ltrace.
Ftrace is an internal tracer designed to find what is going on inside the kernel.
- - ftrace is the most popular Linux alternative to perf.
- - ftrace is the most popular Open Source & free alternative to perf.
ftrace Features
KCachegrind is a profile data visualization tool, used to determine the most time consuming parts in the execution of a program.
Kcachegrind Features
strace is a diagnostic, debugging and instructional userspace utility for Linux. It is used to monitor interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state.
strace Features
DTrace is a performance analysis and troubleshooting tool that is included by default with various operating systems, including Solaris, Mac OS X and FreeBSD. A Linux port is in development.
- - DTrace is the most popular Mac alternative to perf.
DTrace Features
ltrace intercepts and records dynamic library calls which are called by an executed process and the signals received by that process. It can also intercept and print the system calls executed by the program. Used for debugging.
ltrace Features
The ktrace utility enables kernel trace logging for the specified processes. Kernel trace data is logged to the file ktrace.out. The kernel operations that are traced include system calls, namei translations, signal processing, and I/O.
ktrace Features
ktap is a script-based dynamic tracing tool for Linux. It uses a scripting language and lets users trace the Linux kernel dynamically. ktap is designed to give operational insights with interoperability that allows users to tune, troubleshoot and extend the kernel and...
