Using Windows Event Viewer

Bridge operations are also logged in Windows Event Viewer such as a node joining a bridge or a cache connecting to the bridge. This is particularly useful as you can run custom batch scripts on an event in Windows Event Viewer. So, if you want to perform a specific action like initiating state transfer once a cache connects to the bridge, you can do so by calling the Start-BridgeStateTransfer PowerShell cmdlet in your script against that event ID.
