You can view patch compliance information, which tells you the detailed results of the patching process. From the AWS Systems Manger console or APIs, you can easily get aggregate compliance details per instance. In addition, you drill in further and for each instance you can determine which patches are installed, missing, not applicable, and which failed to install.
