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.
