stress-ng. This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces.

christmas-obfuscated-C. Obuscated C Christmas programs

powerstat. Powerstat measures the power consumption of a machine using the battery stats or the Intel RAPL interface. The output is like vmstat but also shows power consumption statistics. At the end of a run, powerstat will calculate the average, standard deviation and min/max of the gathered data.

forkstat. Forkstat is a program that logs process fork(), exec() and exit() activity. It is useful for monitoring system behaviour and to track down rogue processes that are spawning off processes and potentially abusing the system.

pagemon. Pagemon is an interactive memory/page monitoring tool allowing one to browse the memory map of an active running process.

health-check. The health-check tool monitors processes in various ways to help identify areas where it is consuming too many resources. One can trace one or more processes (including all their threads and child processes too) for a full story of system activity.

smemstat. Smemstat reports the physical memory usage taking into consideration shared memory. The tool can either report a current snapshot of memory usage or periodically dump out any changes in memory.

fwts. NOT THE UPSTEAM FWTS REPO, see https://github.com/fwts/fwts instead!

faultstat. page fault tracking tool

linux-next. clone of https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next

cpustat. cpustat periodically dumps out the current CPU utilisation statistics of running processes. cpustat has been optimised to have a minimal CPU overhead and typically uses about 35% of the CPU compared to top. cpustat also includes some simple statistical analysis options that can help characterise the way CPUs are being loaded.

fnotifystat. Fnotifystat is a program that dumps the file system activity in a given period of time.

power-calibrate. Power-calibrate calibrates the power consumption of a mobile device that has a battery power source. It will attempt to calculate the power usage of 1% of CPU utiltisation.

eventstat. Eventstat periodically dumps out the current kernel event state. It keeps track of current events and outputs the change in events on each output update. The tool requires sudo to run since it needs to write to /proc/timer_stats to start and stop the event monitoring.
