    en.wikipedia.org/wiki/Strace

    Linux has ltrace that can trace library and system calls, xtrace that can trace X Window System programs, [69] SystemTap, perf, and trace-cmd and KernelShark that extend ftrace. AIX provides the truss command; HP-UX offers the Tusc command; Solaris / Illumos has truss and DTrace; UnixWare provides the truss command; FreeBSD provides the truss ...

  3. Linux Trace Toolkit - Wikipedia

    en.wikipedia.org/wiki/Linux_Trace_Toolkit

    The Linux Trace Toolkit (LTT) is a set of tools that is designed to log program execution details from a patched Linux kernel and then perform various analyses on them, using console-based and graphical tools. LTT has been mostly superseded by its successor LTTng (Linux Trace Toolkit Next Generation).

  4. traceroute - Wikipedia

    en.wikipedia.org/wiki/Traceroute

    A command is available in many modern operating systems, generally named traceroute in Unix-like systems such as FreeBSD, macOS, and Linux and named tracert in Windows and ReactOS. The functionality was available graphically in macOS, but has been deprecated since the release of macOS Big Sur .

  5. LTTng - Wikipedia

    en.wikipedia.org/wiki/LTTng

    LTTng (Linux Trace Toolkit: next generation) is a system software package for correlated tracing of the Linux kernel, applications and libraries. The project was originated by Mathieu Desnoyers with an initial release in 2005. Its predecessor is the Linux Trace Toolkit.

  6. ptrace - Wikipedia

    en.wikipedia.org/wiki/Ptrace

    ptrace is a system call found in Unix and several Unix-like operating systems.By using ptrace (an abbreviation of "process trace") one process can control another, enabling the controller to inspect and manipulate the internal state of its target. ptrace is used by debuggers and other code-analysis tools, mostly as aids to software development.

  7. DTrace - Wikipedia

    en.wikipedia.org/wiki/DTrace

    eBPF – Linux kernel tracing backend providing a set of features similar to DTrace [30] since kernel version 4.9 ftrace – a tracing framework for the Linux kernel, capable of tracing scheduling events, interrupts, memory-mapped I/O, CPU power state transitions, etc.

  8. MTR (software) - Wikipedia

    en.wikipedia.org/wiki/MTR_(software)

    MTR also has a User Datagram Protocol (UDP) mode (invoked with "-u" on the command line or pressing the "u" key in the curses interface) that sends UDP packets, with the time to live (TTL) field in the IP header increasing by one for each probe sent, toward the destination host. When the UDP mode is used, MTR relies on ICMP port unreachable ...

  9. perf (Linux) - Wikipedia

    en.wikipedia.org/wiki/Perf_(Linux)

    The perf subsystem of Linux kernels from 2.6.37 up to 3.8.8 and RHEL6 kernel 2.6.32 contained a security vulnerability (CVE-2013-2094), which was exploited to gain root privileges by a local user. [ 17 ] [ 18 ] The problem was due to an incorrect type being used (32-bit int instead of 64-bit) in the event_id verification code path.
