我有 AWStats 在两个应用程序上运行，并且未显示操作系统。 反而仅显示“未知”（100％）。所有其他统计数据均被正确解释，只有操作系统出现问题。
这是我的配置：
- AWStats v. 7.5（与 7.1 相同）
- Perl v.5.16
- IIS 7
这里样本日志，即用作输入使用上面的日志格式。为了看得更清楚，我插入了换行符。
%time2 %other %other %logname
2016-05-11 00:31:51 W3SVC7 <Servername>
%other %method %url %other %other %logname %host %other
<SIP> GET <URL> - 443 - <ClientIP> HTTP/1.1
%ua %other
Mozilla/5.0+(Windows+NT+6.1;+WOW64;+Trident/7.0;+rv:11.0)+like+Gecko -
%referer %other %code %other %other %bytesd %other %other
<cookie> <domain> 200 0 0 55076 371 78
这是为应用程序定义的一行日志格式：
LogFormat="%time2 %other %other %other %method %url %other %other %logname %host %other %ua %other %referer %other %code %other %other %bytesd %other %other"
这是日志条目
2016-05-11 00:31:51 W3SVC7 <Servername> <SIP> GET <URL> - 443 - <ClientIP> HTTP/1.1 Mozilla/5.0+(Windows+NT+6.1;+WOW64;+Trident/7.0;+rv:11.0)+like+Gecko - >cookie> <domain> 200 0 0 55076 371 78
当我将 Windows 更改为 Linux、操作系统版本或其他参数时，情况也是如此。即使对于另一种用空格代替加号并用 " 包围的格式，我也会得到相同的结果。
这是我的一个应用程序的配置文件，另一个几乎相同：
