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;
}
