EC2 Windows troubleshooting utilities

The EC2WinUtil driver provides the following types of troubleshooting support for your Windows instance.

Crash call stacks

EC2WinUtil collects basic crash information from your instance and writes it out to the serial console. The following list includes some of the key details that the utility writes to the console.

  • Identification of the module that generated the fault.

  • The Windows error code associated with the event.

  • A stack trace of the most recent calls.

With these details, you can perform initial root cause analysis and determine if further analysis is needed. Output to the serial console also enables AWS to track crash trends for Amazon EC2 drivers, and diagnose large scale crash events.

Note

EC2WinUtil doesn't collect any customer data in its crash call stacks.

Hibernate/resume stability

EC2WinUtil tracks the virtualization settings of the instance across hibernate/resume cycles. This helps to improve the long-term stability of instances that have enabled hibernation.
