Configuring Inventory Collection

This section describes how to configure inventory collection on one or more managed instances by using the Amazon EC2 console. This section also describes how to aggregate inventory data from multiple AWS accounts and regions in a single Amazon S3 bucket by using Systems Manager Resource Data Sync. For an example of how to configure inventory collection using the AWS CLI, see Systems Manager Inventory Manager Walkthroughs.

Before You Begin

Before you configure inventory collection, complete the following tasks.

  • Update SSM Agent on the instances you want to inventory. By running the latest version of SSM Agent, you ensure that you can collect metadata for all supported inventory types. For information about how to update SSM Agent by using State Manager, see Walkthrough: Automatically Update the SSM Agent.

  • Verify that your instances meet Systems Manager prerequisites. For more information, see Systems Manager Prerequisites.

  • (Optional) Create a JSON file to collect custom inventory. For more information, see Working with Custom Inventory.

Configuring Collection

Use the following procedure to configure inventory collection on a managed instance using the Amazon EC2 console.


When you configure inventory collection, you start by creating a Systems Manager State Manager association. Systems Manager collects the inventory data when the association is run. If you don't create the association first, and attempt to invoke the aws:softwareInventory plugin by using, for example, Run Command, the system returns the following error:

The aws:softwareInventory plugin can only be invoked via ssm-associate.

Also note that an instance can have only have one Inventory association configured at a time. If you configure an instance with two or more associations, the association doesn't run and no inventory data is collected.

The following procedure describes steps that you perform in the Amazon EC2 console. You can also perform these steps in the new AWS Systems Manager console. The steps in the new console will differ from the steps below.

To configure inventory collection

  1. Open the Amazon EC2 console, expand Systems Manager Shared Resources in the navigation pane, and then choose Managed Instances.

  2. Choose Setup Inventory.

  3. In the Targets section, choose Specify a Tag if you want to configure inventory on multiple instances using EC2 tags. Choose Manually Select Instances if you want to individually choose which instances are configured for inventory.


    If you use tags, any instances created in the future with the same tag will also report inventory.

  4. In the Schedule section, choose how often you want the system to collect inventory metadata from your instances.

  5. In the Parameters section, use the lists to enable or disable different types of inventory collection. See the following samples if you want to create an inventory search for Files or the Windows Registry.


    • On Linux, collect metadata of .sh files in the /home/ec2-user directory, excluding all subdirectories.

      [{"Path":"/home/ec2-user","Pattern":["*.sh", "*.sh"],"Recursive":false}]
    • On Windows, collect metadata of all ".exe" files in the Program Files folder, including subdirectories recursively.

      [{"Path":"C:\Program Files","Pattern":["*.exe"],"Recursive":true}]
    • On Windows, collect metadata of specific log patterns.

    • Limit the directory count when performing recursive collection.

      [{"Path":"C:\Users","Pattern":["*.ps1"],"Recursive":true, "DirScanLimit": 1000}]

    Windows Registry

    • Collect all keys and values recursively for a specific path.

      [{"Path":"HKEY_LOCAL_MACHINE\SOFTWARE\Amazon","Recursive": true}]
    • Collect all keys and values for a specific path (recursive search disabled).

      [{"Path":"HKEY_LOCAL_MACHINE\SOFTWARE\Intel\PSIS\PSIS_DECODER", "Recursive": false}]
    • Collect a specific key by using the ValueNames option.


    For more information about collecting File and Windows Registry inventory, see Working with File and Windows Registry Inventory.

  6. In the Advanced section, choose Write to S3 if you want to store the association execution status in an Amazon S3 bucket.

  7. Choose Setup Inventory and then choose OK.

  8. In the Managed Instances page, choose an instance that you just configured for inventory and choose the Description tab. The Association Status shows Pending until the association is created. If the status is Failed, verify that you have the latest version of the SSM Agent installed on your instances.

  9. After the collection time-frame has passed, choose a managed instance, and then choose the Inventory tab.

  10. Use the Inventory Type list to filter on different types of inventory data.

After you configure Inventory collection, we recommend that you configure Systems Manager Resource Data Sync. Resource Data Sync centralizes all Inventory data in a target Amazon S3 bucket and automatically updates the central storage when new Inventory data is collected. With all Inventory data stored in a target Amazon S3 bucket, you can then use services like Amazon Athena and Amazon QuickSight to query and analyze the aggregated data. For more information, see Configuring Resource Data Sync for Inventory.
