Patch Manager Prerequisites
SSM Agent Version
Version 2.0.834.0 or later of SSM Agent be running on the instances you want to manage with Patch Manager.
Note
SSM Agent is updated whenever changes are made to Systems Manager and when new capabilities are added. To ensure that your instances are always running the newest version of SSM Agent, we recommend that you update the agent automatically whenever a new version is available using either of the following methods.
-
Use a State Manager association. For information, see the State Manager topic Automatically Update SSM Agent (CLI).
-
Use a Maintenance Window. For information, see the Maintenance Window topics Automatically Update SSM Agent (AWS CLI) and Automatically Update SSM Agent (Console).
You can also use Run Command to manually update one or more instances with the latest version. For more information, see Automatically Update SSM Agent (CLI) (State Manager) and Update SSM Agent by using Run Command.
