如何检测某个进程占用多少CPU
如题！现在是某个进程经常占用CPU50% 我想做个程序检测他 发现超过50% 就杀
没超过就潜伏着 你先考虑考虑au3做实时监控要费多少再说吧 好像有个UDF可以做到，找找吧 ;====================================================================================
; Function Name: _ProcessListProperties()
; Description: Get various properties of a process, or all processes
; Call With: _ProcessListProperties([$Process[, $sComputer]])
; Parameter(s): (optional) $Process - PID or name of a process, default is "" (all)
; (optional) $sComputer - remote computer to get list from, default is local
; Requirement(s): AutoIt v3.2.4.9+
; Return Value(s):On Success - Returns a 2D array of processes, as in ProcessList()
; with additional columns added:
; - Number of processes listed (can be 0 if no matches found)
; - 1st process name
; - 1st process PID
; - 1st process Parent PID
; - 1st process owner
; - 1st process priority (0 = low, 31 = high)
; - 1st process executable path
; - 1st process CPU usage
; - 1st process memory usage
; - 1st process creation date/time = "MM/DD/YYY hh:mm:ss" (hh = 00 to 23)
; - 1st process command line string
; ...
; thru - last process properties
; On Failure: Returns array with = 0 and sets @Error to non-zero (see code below)
; Author(s): PsaltyDS at http://www.autoitscript.com/forum
; Date/Version: 09/17/2008--v2.0.3
; Notes: If an integer PID or string process name is provided and no match is found,
; then = 0 and @error = 0 (not treated as an error, same as ProcessList)
; This function requires admin permissions to the target computer.
; All properties come from the Win32_Process class in WMI.
; To get time-base properties (CPU and Memory usage), a 100ms SWbemRefresher is used.
