簡(jiǎn)單的php獲取linux服務(wù)器狀態(tài)的代碼，不多說(shuō)-直接上函數(shù)：
復(fù)制代碼 代碼如下:
function get_used_status(){
$fp = popen('top -b -n 2 | grep -E "^(Cpu|Mem|Tasks)"',"r");//獲取某一時(shí)刻系統(tǒng)cpu和內(nèi)存使用情況
$rs = "";
while(!feof($fp)){
$rs .= fread($fp,1024);
}
pclose($fp);
$sys_info = explode("/n",$rs);
$tast_info = explode(",",$sys_info[3]);//進(jìn)程 數(shù)組
$cpu_info = explode(",",$sys_info[4]); //CPU占有量 數(shù)組
$mem_info = explode(",",$sys_info[5]); //內(nèi)存占有量 數(shù)組
//正在運(yùn)行的進(jìn)程數(shù)
$tast_running = trim(trim($tast_info[1],'running'));
//CPU占有量
$cpu_usage = trim(trim($cpu_info[0],'Cpu(s): '),'%us'); //百分比
//內(nèi)存占有量
$mem_total = trim(trim($mem_info[0],'Mem: '),'k total');
$mem_used = trim($mem_info[1],'k used');
$mem_usage = round(100*intval($mem_used)/intval($mem_total),2); //百分比
/*硬盤使用率 begin*/
$fp = popen('df -lh | grep -E "^(/)"',"r");
$rs = fread($fp,1024);
pclose($fp);
$rs = preg_replace("http://s{2,}/",' ',$rs); //把多個(gè)空格換成 “_”
$hd = explode(" ",$rs);
$hd_avail = trim($hd[3],'G'); //磁盤可用空間大小 單位G
$hd_usage = trim($hd[4],'%'); //掛載點(diǎn) 百分比
//print_r($hd);
/*硬盤使用率 end*/
//檢測(cè)時(shí)間
$fp = popen("date +/"%Y-%m-%d %H:%M/"","r");
$rs = fread($fp,1024);
pclose($fp);
$detection_time = trim($rs);
/*獲取IP地址 begin*/
/*
$fp = popen('ifconfig eth0 | grep -E "(iNET addr)"','r');
$rs = fread($fp,1024);
pclose($fp);
$rs = preg_replace("http://s{2,}/",' ',trim($rs)); //把多個(gè)空格換成 “_”
$rs = explode(" ",$rs);
$ip = trim($rs[1],'addr:');
*/
/*獲取IP地址 end*/
/*
$file_name = "/tmp/data.txt"; // 絕對(duì)路徑: homedata.dat
$file_pointer = fopen($file_name, "a+"); // "w"是一種模式，詳見后面
fwrite($file_pointer,$ip); // 先把文件剪切為0字節(jié)大小， 然后寫入
fclose($file_pointer); // 結(jié)束
*/
return array('cpu_usage'=>$cpu_usage,'mem_usage'=>$mem_usage,'hd_avail'=>$hd_avail,'hd_usage'=>$hd_usage,'tast_running'=>$tast_running,'detection_time'=>$detection_time);
}
