如何在事件日志中查找应用程序池回收

我已经在 IIS 7.5中配置了一个应用程序池，以便在内存使用超过一定水平时进行回收。我还将其配置为记录此信息。

我应该在事件日志的哪个地方找到这个？

我尝试过基于所有 IIS 项目的源进行过滤，例如‘ IIS-W3SVC-WP’、‘ IIS-IISManager’等等，但是什么都没有。

我可以看到，它正在添加的项目从’IIS-配置’的日志太，我启用。但还是什么都没有。

It seemed quite hard to find this information, but eventually, I came across this question
You have to look at the 'System' event log, and filter by the WAS source.
Here is more info about the WAS (Windows Process Activation Service)

As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:

Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}

From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.

This along with @BlackHawkDesign comment should help you find what you need.

I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00

As link-only answers are not preferred, I will just copy and paste the content of the link of the accepted answer

It is definitely System Log.

Which Log file? Well -- you can check the physical path by right-clicking on the System Log (e.g. Server Manager | Diagnostics | Event Viewer | Windows Logs). The default physical path is %SystemRoot%\System32\Winevt\Logs\System.evtx.

You can create a Custom Filter and filter by "Source: WAS" to quickly see only entries generated by IIS.

You may need first to enable logging of such even for a specific App Pool -- by default App Pool has only 3 recycle events out of 8 enabled. To change it using GUI: II S Manager | Application Pools | Select App Pool -> Advanced Settings | Generate Recycle Event Log Entry.
