Create a maintenance window from the Systems Manager console

To create an AMS Accelerate maintenance window from the Systems Manager console, follow these steps:

1. In the left navigation bar in the Change management area, click Maintenance Windows, and then click Create Maintenance Window at the top right of the screen. Fill in the form. For details on any of the options, see Create a maintenance window (console). When finished, click Create maintenance window.

   The maintenance windows list page opens.

2. Select the newly created maintenance window.

   The maintenance window details page opens.

3. Go to the Targets tab and choose Register target.

   The Register target page opens.

4. Add your Accelerate target. For information on targets, see Assign targets to a maintenance window (console). When finished, click Register target. Make note of the target as you need it later.

   The maintenance windows details page reopens on the Targets tab with a list including the new target.

5. On the Tasks tab of the maintenance window details page, choose Register Task, and then pick Register Automation task from the drop-down list. Fill in the form. Accelerate notes:

   • Provide a meaningful task name. For example: AcceleratePatch.

   • In the Automation document area click in the search box, choose Owner, then Shared documents.

   • Select the automation document by clicking in the search box and choosing Document name prefix --> Equals and then typing: AWSManagedServices-PatchInstance. Then select the AWSManagedServices-PatchInstance document by selecting its radio button.

   • Under document version, choose Default version at runtime.

   • In the Targets section:

     • Set Target by: to Selecting registered target groups.

     • In the list of targets, select the target you registered in the Targets tab.

   • In the Input parameters section, fill in the form.

     • InstanceId: {{TARGET_ID}}

     • StartInactiveInstances: True to start the instances if they are stopped during the patch maintenance window.

       Note

       The InstanceId parameter value is case sensitive and the StartInactiveInstances parameter value can be either True or False.

       Stopped instances cannot be started when targeted by tags. For more information, see No Invocations to Execute.

   • In the Rate control section, choose percentages. AMS Accelerate recommends 100% for Concurrency and 100% for Error threshold to attempt to patch all instances simultaneously, regardless of automation errors. If you wish to patch half your targets at a time, for example, to keep a half of the target instances behind a load balance running, set Concurrency to 50%.

   • In the IAM service role section,choose Use a custom service role, then choose the ams_ssm_automation_role.

   Click Register Automation task.

   The patching maintenance window is created. Under the Description tab, you can see the Next execution time.
