- Sample CPU usage data from kern.cp_times, this makes for a far more accurate and scheduler independent algorithm. - Rip out the process list scraping that is no longer required. - Don't update CPU usage sampling on every request, but every 15s instead. This makes it impossible for an attacker to hide the CPU load by triggering 4 samplings in short succession when the system is idle. - After reaching the steady-state, the system will always report the average CPU load of the last 60 sampled seconds. - Untangling of call graph. PR: kern/130222 Tested by: Julian Dunn <jdunn@aquezada.com> Gustau Pérez <gperez@entel.upc.edu> Jürgen Weiß <weiss@uni-mainz.de> MFC after: 2 weeks I'm unsure if some MIB standard states this must be the load average for, eg. 300s, it looks like net-snmp isn't even bothering to implement the CPU load reporting at all.
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
