簡單的php獲取linux服務(wù)器狀態(tài)的代碼，不多說-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);
 }
