我有一台主要服务器和4台电脑连接。 我怎么能够学习哪一种计算机如何使用CPU和磁盘。

为此,Qt没有APIC。 你们需要利用本土的土著预报平台。
或许可以帮助你:
#include <QDebug>
#include <QProcess>
int main(void){
setenv("LC_NUMERIC", "C",1);
QProcess process;
process.start("/usr/bin/uptime",{},QIODevice::ReadWrite);
process.waitForFinished();
//Get results
QString output = process.readAllStandardOutput();
QString err = process.readAllStandardError();
//Get load portion
QString loads=output.section("load average: ",1,1);
QString load_lastmin=loads.section(" ",0,0);
load_lastmin.remove(load_lastmin.size()-1,1);
//For debug
qDebug() << "Output:" << output;
qDebug() << "Error:" << err;
qDebug() << "Loads:" << loads;
qDebug() << "Load last min:" << load_lastmin;
return 0;
}
成果实例:
Output: " 10:04:33 up 3 days, 21:39, 1 user, load average: 0.55, 0.71, 0.78
"
Error: ""
Loads: "0.55, 0.71, 0.78
"
Load last min: "0.55"
