内存查看平台化
来源：互联网 发布：linux如何退出top 编辑：程序博客网 时间：2024/06/06 15:36
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
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("\n"); 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;}附其他代码：
