一种获取pid信息与资源的方式

什么也不说了，上例子看吧。

# -*- coding: utf-8-*-
import psutil

def get_proc_by_id(pid):
    return psutil.Process(pid)

def get_proc_by_name(pname):
    """ get process by name

    return the first process if there are more than one
    """
    for proc in psutil.process_iter():
        try:
            if proc.name().lower() == pname.lower():
                return proc  # return if found one
        except psutil.AccessDenied:
            pass
        except psutil.NoSuchProcess:
            pass
    return None



if '__main__' == __name__:
    print get_proc_by_name("chrome.exe")
    print get_proc_by_id(9604)
    proc = psutil.Process(9604)

    total = psutil.virtual_memory().total
    #rss, vss = proc.memory_info()
    percent = proc.memory_percent()

    #print "rss: %s Byte, vss: %s Byte" % (rss, vss)
    print "total: %.2f(M)" % (float(total)/1024/1024/1024)
    #print "percent: %.2f%%, calc: %.2f%%" % (percent, 100*float(rss)/total)
