How to Find App Pool Recycles in Event Log

Question

I have configured an app pool in IIS 7 5 to recycle when the memory usage goes above a certain level  I have also configured it to log this information   Where in the event log should I look for this   I have tried filtering based on the source being all the IIS items  e g   IIS-W3SVC-WP    IIS-IISManager   and all the rest  but nothing   I can see that it is adding in the items from the  IIS-Configuration  log too which I enabled  But still nothing

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
