分享一段php获取linux服务器状态的代码
正在做的项目中,需要使用php获取Linux服务器状态,度娘了一下,发现绝大部分都是基于WIN系统的,好吧,自力更生,分享给大家一段Linux的代码
简单的php获取linux服务器状态的代码,不多说-直接上函数:
function get_used_status(){ $fp = popen('top -b -n 2 | grep -E "^(Cpu|Mem|Tasks)"',"r");//获取某一时刻系统cpu和内存使用情况 $rs = ""; while(!feof($fp)){ $rs .= fread($fp,1024); } pclose($fp); $sys_info = explode("\n",$rs);$tast_info = explode(",",$sys_info[3]);//进程 数组 $cpu_info = explode(",",$sys_info[4]); //CPU占有量 数组 $mem_info = explode(",",$sys_info[5]); //内存占有量 数组
//正在运行的进程数 $tast_running = trim(trim($tast_info[1],'running')); //CPU占有量 $cpu_usage = trim(trim($cpu_info[0],'Cpu(s): '),'%us'); //百分比 //内存占有量 $mem_total = trim(trim($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
/*硬盘使用率 begin*/ $fp = popen('df -lh | grep -E "^(/)"',"r"); $rs = fread($fp,1024); pclose($fp); $rs = preg_replace("/\s{2,}/",' ',$rs); //把多个空格换成 “_” $hd = explode(" ",$rs); $hd_avail = trim($hd[3],'G'); //磁盘可用空间大小 单位G $hd_usage = trim($hd[4],'%'); //挂载点 百分比 //print_r($hd); /*硬盘使用率 end*/ //检测时间 $fp = popen("date +\"%Y-%m-%d %H:%M\"","r"); $rs = fread($fp,1024); pclose($fp); $detection_time = trim($rs); /*获取IP地址 begin*/ /* $fp = popen('ifconfig eth0 | grep -E "(inet addr)"','r'); $rs = fread($fp,1024); pclose($fp); $rs = preg_replace("/\s{2,}/",' ',trim($rs)); //把多个空格换成 “_” $rs = explode(" ",$rs); $ip = trim($rs[1],'addr:'); */ /*获取IP地址 end*/ /* $file_name = "/tmp/data.txt"; // 绝对路径: homedata.dat $file_pointer = fopen($file_name, "a+"); // "w"是一种模式,详见后面 fwrite($file_pointer,$ip); // 先把文件剪切为0字节大小, 然后写入 fclose($file_pointer); // 结束 */ return array('cpu_usage'=>$cpu_usage,'mem_usage'=>$mem_usage,'hd_avail'=>$hd_avail,'hd_usage'=>$hd_usage,'tast_running'=>$tast_running,'detection_time'=>$detection_time); }
