AWS Diagnostics for Microsoft Windows Server is an easy to use tool that you can run on your EC2 Windows Server instances. It is a very valuable tool not just for collecting log files and troubleshooting issues, but also proactively looking for possible areas of concern.
This tool can, for example, be used to diagnose configuration issues between the Windows Firewall and the Amazon EC2 security groups that may affect your applications. It can even examine EBS boot volumes from other instances and collect relevant logs for troubleshooting Windows Server from the volume.
