• 内存查看平台化

    针对linux服务器，用平台一键同步时间、查看内存占用、磁盘占用，由于采用用户名，密码登录SSH远程登录拿取数据，所以不需要安装客户端

    查看内存占用

    平台根据远程服务器的登录名，密码，ssh登录远程服务器，执行cat /proc/meminfo获取数据

    public int[] viewMemory(String ip) throws IOException, InterruptedException
	{
		 RemoteShellTool tool = new RemoteShellTool(ip,"utf-8");
		 tool.loginCentos();
		 String returnString = tool.exec("cat /proc/meminfo"); 
		 
		 int  data[];
		 
		 if(returnString.indexOf("MemTotal")<0)
		 {
			 logger.info("viewMemory:"+ip+" return "+returnString);	
			 data=new int[]{0,0};
		 }
		 else {
			 returnString=returnString.replace(" ", "");
			 String result[]=returnString.split("
");
			 
			 int total = (int) ((Integer.parseInt(result[0].substring(9,result[0].length()-2))+0.5)/1024);
			 int free = (int) ((Integer.parseInt(result[1].substring(8,result[1].length()-2))+0.5)/1024);
			 data=new int[]{free,total};
		}
		 return data;
	}
