如果开启了登录回收功能，您可以在事件查看器(系统日志)中看到这一点.

If logging on recycles is turned on you can see this in the Event Viewer (System Log).

如果不是，您可以使用 PerfMon 计数器查看 W3WP.exe 上代表您的应用程序池的 Process-Elapsed Time(这将是自上次回收以来的秒数)

If it's not you can use PerfMon counters to see Process-Elapsed Time on the W3WP.exe representing your application pool (which will be the number of seconds since the last recycle)
