我正在尝试使用Log Parser Studio查看IIS日志，以确定某些IP地址最近访问过一个网站的时间。我使用以下查询至少可以让我对日志的使用寿命有所了解：
select c-ip, count(c-ip) as requestcount from '[LogFilePath]' group by c-ip order by count(c-ip) desc
我在修改它以获取具有“最后访问”日期的IP地址信息时遇到麻烦。这样的事情可能吗？还是有更好的方法去实现我想要的？
理想情况下，我想利用此查询来审核日志，并在IP地址经过X天的闲置时间后....基于IP地址撤消访问权限（在防火墙处删除访问权限，IP地址位于白名单）。
由于网站/应用程序的性质，有时候IP在90-120天内无法访问，因此使用简单的“点击计数”是行不通的。错误地删除仍然有效的IP地址的访问可能很容易，重启防火墙后，命中计数将被重置。
谢谢。

在查询中添加MAX（DATE）。
