We've compiled a list of 7 free and paid alternatives to ktrace. The primary competitors include ftrace, ltrace. In addition to these, users also draw comparisons between ktrace and strace, DTrace, ktap. Also you can look at other similar options here: Development Tools.

Kernel process trace logging for the individual processes.
Kernel process trace logging for the individual processes.
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.
Once tracing is enabled on a process, trace data will be logged until either the process exits or the trace point is cleared. A traced process can generate enormous amounts of log data quickly; It is strongly suggested that users memorize how to disable tracing before attempting to trace a process. The following command is sufficient to disable tracing on all user-owned processes, and, if executed by root, all processes:
$ ktrace -C
The trace file is not human readable; use kdump(1) to decode it.
The utility may be used only with a kernel that has been built with the "KTRACE" option in the kernel configuration file.
