Remediation

From Command Line​

To enable CloudWatch logging for all key components on an existing AWS DMS Replication Task, use the AWS CLI’s modify-replication-task command with an updated Settings JSON payload.

Retrieve the current task settings​

aws dms describe-replication-tasks \
  --filters Name=replication-task-arn,Values={{replication-task-arn}} \
  --query "ReplicationTasks[0].ReplicationTaskSettings" \
  --output json > {{current-settings}}.json

Update settings to include Logging​

{
  "Logging": {
    "EnableLogging": true,
    "LogComponents": [
      {
        "Component": "TARGET_LOAD",
        "Severity": "LOGGER_SEVERITY_DEFAULT"
      },
      {
        "Component": "TARGET_APPLY",
        "Severity": "LOGGER_SEVERITY_DEFAULT"
      },
      {
        "Component": "SOURCE_CAPTURE",
        "Severity": "LOGGER_SEVERITY_DEFAULT"
      },
      {
        "Component": "SOURCE_UNLOAD",
        "Severity": "LOGGER_SEVERITY_DEFAULT"
      }
    ]
  }
}

Apply the modified settings immediately​

aws dms modify-replication-task \
  --replication-task-arn {{replication-task-arn}} \
  --replication-task-settings file://{{current-settings}}.json \
  --apply-immediately
