stress-ng development
Cur síos
I'm hoping to upgrade by development server so that I can host my 90+ virtual machines I use for regression testing. Currently it takes me 2+ days to regression test stress-ng on my old server as I'm emulating a lot of architectures in QEMU and it's relatively slow.

stress-ng Réaltaí 2700 Nuashonraithe an tseachtain seo
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.

powerstat Réaltaí 183 Nuashonraithe 4 mhí ó shin
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.
pagemon Réaltaí 47 Nuashonraithe 4 mhí ó shin
Pagemon is an interactive memory/page monitoring tool allowing one to browse the memory map of an active running process.
forkstat Réaltaí 115 Nuashonraithe 1 bhliain ó shin
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.
cpustat Réaltaí 20 Nuashonraithe 1 bhliain ó shin
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.
health-check Réaltaí 38 Nuashonraithe 2 bhliain ó shin
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.

x86 cyclic latency sleep test
smemstat Réaltaí 36 Nuashonraithe 2 bhliain ó shin
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.
sluice Réaltaí 9 Nuashonraithe 2 bhliain ó shin
Sluice is a program that reads input on stdin and outputs on stdout at a specified data rate.
readtsc Réaltaí 2 Nuashonraithe 2 bhliain ó shin
X86 TSC reader
power-calibrate Réaltaí 13 Nuashonraithe 2 bhliain ó shin
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.

tool to force pages in
fnotifystat Réaltaí 16 Nuashonraithe 2 bhliain ó shin
Fnotifystat is a program that dumps the file system activity in a given period of time.
faultstat Réaltaí 22 Nuashonraithe 2 bhliain ó shin
page fault tracking tool
eventstat Réaltaí 12 Nuashonraithe 2 bhliain ó shin
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.
