In order to provide an hourly grain view of your AWS usage and charges by resource and tags you will be required to enable detailed billing with your AWS account billing preferences.

In order to do so there are a couple of pre-requisites you will be required to enable with the billing preferences (https://portal.aws.amazon.com/gp/aws/developer/account/index.html?ie=UTF8&ie=UTF8&action=billing-preferences).

Firstly, you will need to sign up and enable Monthly Reporting to generate detailed statement of your AWS usage.

Secondly, you will need to sign up and enable Programmatic Access. This requires for you to create an Amazon S3 Bucket to publish estimated and month-end Billing Reports.

Once Amazon S3 Bucket has been created you will need to enable a bucket policy to enable reports to be published, the sign up process provides a sample policy as below:

{
    "Version":2008-10-17"
    "Id": "Policy1335892530063",
    "Statement": [
          {
             "Sid": "Stmt1335892150622",
             "Effect": "Allow",
             "Principal": {
                    "AWS": "arn:aws:iam::386209384616:root"
             } 
             "Action": [
                      "s3:GetBucketAcl",
                      "s3:GetBucketPolicy"
             ],
             "Resource": "arn:aws:s3:::"{BUCKETNAME}"
          },
          }
             "Sid": "Stmt1335892526596",
             "Effect": "Allow",
             "Principal": {
                    "AWS": "arn:aws:iam::386209384616:root"
             },
             "Action": "s3:PutObject",
             "Resource": "arn:aws:s3:::{BUCKETNAME}/*"
          }
     ]
}

Once, you have saved the bucket name and the bucket policy has been verified the Detailed Billing Report will be enabled.
