DTrace is described as 'Performance analysd troubleshooting tool that is included by default with various operating systems, including Solaris, Mac OS X and FreeBSD. A Linux port is in development' and is an app in the development category. There are eight alternatives to DTrace for Linux, BSD, FreeBSD and Mac. The best DTrace alternative is SystemTap, which is both free and Open Source. Other great apps like DTrace are lurk, strace, perf and ftrace.
SystemTap provides free software (GPL) infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go through the tedious and disruptive...
Lurk allows the user to trace system calls of a process or of a command. In contrast to strace, lurk focuses on a simple, yet pretty, user experience while implementing the most important use cases of strace.
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.
perf is a 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.
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.
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.
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...
