Linux System software package for correlated tracing of kernel, applications and libraries. GPL/LGPL/MIT OProfile: Linux Profiles everything running on the Linux system, including hard-to-profile programs such as interrupt handlers and the kernel itself. Sampling profiler for Linux that counts cache misses, stalls, memory fetches, etc.
In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.
The program produces an ordered list of running processes selected by user-specified criteria, and updates it periodically. Default ordering is by CPU usage, and only the top CPU consumers are shown. top shows how much processing power and memory are being used, as well as other information about the running processes.
In computing, SystemTap (stap) is a scripting language and tool for dynamically instrumenting running production Linux-based operating systems.System administrators can use SystemTap to extract, filter and summarize data in order to enable diagnosis of complex performance or functional problems.
System Mechanic is an easy solution for optimal PC performance and simple computing. Once downloaded, it helps speed up slow computers by removing unnecessary software and files and fixes problems ...
iostat (input/output statistics) is a computer system monitor tool used to collect and show operating system storage input and output statistics. It is often used to identify performance issues with storage devices, including local disks, or remote disks accessed over network file systems such as NFS.
systemd-analyze may be used to determine system boot-up performance statistics and retrieve other state and tracing information from the system and service manager. systemd tracks processes using the Linux kernel's cgroups subsystem instead of using process identifiers (PIDs); thus, daemons cannot "escape" systemd, not even by double-forking.
