Systems Manager Fleet Manager does not have SSM-SessionManagerRunShell document


I'm trying to use Systems Manager Fleet Manager to view "Performance counters", "Processes", etc. However, when trying to load those pages, I see the following error message in a red banner at the top of the page:

Fleet Manager is unable to start the session. InvalidDocument: Document with name SSM-SessionManagerRunShell does not exist.

Looking at the documents present in Systems Manager, I can see a document called AWS-RunShellScript, but none by the name that this page is looking for.

How can I get this document set up?

According to the documentation, "SSM-SessionManagerRunShell" is automatically set up when using a session manager.

When you configure Session Manager for your account, the system creates a Session type document SSM-SessionManagerRunShell. This document stores your session preferences, such as whether session data is saved in an Amazon Simple Storage Service (Amazon S3) bucket or Amazon CloudWatch Logs log group, whether session data is encrypted using AWS Key Management Service (AWS KMS), and whether Run As support is allowed for your sessions. The following is an example.

Also, looking at the questions below, it seems like this is a temporary issue and will be resolved over time.

  • I found the same thread on, but that doesn't seem relevant here, as I haven't "switched from basic/standard to advanced tiers".


I had the same issue today.. Before you can set a password for your new user, AWS KMS encryption must be enabled in your session preferences.

I had to enabled KMS in Session Manager Session Preferences. You will require a Customer Manged KMS key that SSM and Users can use
