I'm trying to get the EC2 UserData script logs and direct them to system logs on Windows.
On Linux, someone already found out the solution (http://alestic.com/2010/12/ec2-user-data-output). Basically you'd tee /var/log/user-data.log to system logs.
I need to know how to do it for Windows instances. I could not find any user-data.log on my windows instance.
For those who find this and are still looking you can try looking in ProgramData. There are a couple log files in there that give you more info about boot.
C:\ProgramData\Amazon\EC2-Windows\Launch\Log\Ec2Launch.log
C:\ProgramData\Amazon\EC2-Windows\Launch\Log\UserdataExecution.log
