Running commands on managed nodes
This section includes information about how to send commands from the Amazon Systems Manager console to managed nodes. This section also includes information about how to cancel a command.
Note that if your node is configured with the noexec mount option for the
var directory, Run Command is unable to successfuly run commands.
Important
When you send a command using Run Command, don't include sensitive information
formatted as plaintext, such as passwords, configuration data, or other secrets. All
Systems Manager API activity in your account is logged in an S3 bucket for Amazon CloudTrail logs.
This means that any user with access to S3 bucket can view the plaintext values
of those secrets. For this reason, we recommend creating and using
SecureString parameters to encrypt sensitive data you use in
your Systems Manager operations.
For more information, see Restricting access to Parameter Store parameters using IAM policies.
Execution history retention
The history of each command is available for up to 30 days. In addition, you can store a copy of all log files in Amazon Simple Storage Service or have an audit trail of all API calls in Amazon CloudTrail.
