The primary method to diagnose a failed OpsWorks recipe execution is to log in to the failed instances and check the local logs. By accessing the local logs, you can gain valuable insights into what went wrong during the execution of the recipe. These logs typically contain error messages, stack traces, and other diagnostic information that can help pinpoint the source of the failure. This method allows for a detailed examination of the execution environment and the specific commands that may have failed, making it the most effective approach for troubleshooting.

Additionally, while examining the OpsWorks dashboard can provide an overview of the deployment and may highlight areas of concern, it often does not provide the level of detail found in the local logs of the instances where the execution failed. Network settings might affect connectivity, and restarting instances might temporarily resolve issues but does not address the underlying problem. Therefore, accessing the logs on the instances directly ensures a thorough investigation into the failure.
