  2. perf (Linux) - Wikipedia

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

    It supports hardware performance counters, tracepoints, software performance counters (e.g. hrtimer), and dynamic probes (for example, kprobes or uprobes). [4] In 2012, two IBM engineers recognized perf (along with OProfile ) as one of the two most commonly used performance counter profiling tools on Linux.

    en.wikipedia.org/wiki/Lm_sensors

    lm_sensors (Linux-monitoring sensors) is a free open-source software-tool for Linux that provides tools and drivers for monitoring temperatures, voltage, humidity, and fans. It can also detect chassis intrusions. [citation needed]

  4. watch (command) - Wikipedia

    en.wikipedia.org/wiki/Watch_(command)

    watch is a command-line tool, part of the Linux procps and procps-ng packages, that runs the specified command repeatedly and displays the results on standard output so the user can watch it change over time. By default, the command is run every two seconds, although this is adjustable with the -n secs argument.

  5. Hardware performance counter - Wikipedia

    en.wikipedia.org/wiki/Hardware_performance_counter

    In computers, hardware performance counters (HPC), [1] or hardware counters are a set of special-purpose registers built into modern microprocessors to store the counts of hardware-related activities within computer systems. Advanced users often rely on those counters to conduct low-level performance analysis or tuning.

    en.wikipedia.org/wiki/Self-Monitoring,_Analysis...

    Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T. or SMART) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [3] Its primary function is to detect and report various indicators of drive reliability, or how long a drive can function while anticipating imminent hardware failures.

  8. Linux framebuffer - Wikipedia

    en.wikipedia.org/wiki/Linux_framebuffer

    Knoppix booting on the framebuffer. The Linux framebuffer (fbdev) is a linux subsystem used to show graphics on a computer monitor, typically on the system console. [1]It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and ...

  9. traceroute - Wikipedia

    en.wikipedia.org/wiki/Traceroute

    The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
