License Summary

This sample code is made available under a modified MIT license. See the LICENSE file.

AWS Costs

• AWS Lambda Invocation
  • Usually Free
• Amazon SES
  • Usually Free
• Amazon S3
  • Minimal usage
• AWS Cost Explorer API calls
  • $0.01 per API call (about 25 calls per run)

Prerequisites

• awscli
• Configure AWS credentials for target account
  • run aws configure
• Cost Explorer enabled
• Verfied Amazon SES Sender email
• If you verify an email, you can send from/to that address.
• To send to other addresses, you need to move SES out of sandbox mode.

Docker (optional for building the lambda python package with updated https://pypi.python.org/ third-party libraries)

Easy Deploy (us-east-1 only)

If you do not need to modify the code, just deploy the included easy_deploy.yaml using AWS Cloudformation via the console.

Deploying (SAM / Script)

Update the values in deploy.sh for your AWS account details.

Variable	Description
S3_BUCKET	S3 Bucket to use
SES_SEND	Email list to send to (comma separated)
SES_FROM	SES Verified Sender Email
SES_REGION	SES Region
COST_TAGS	List Of Cost Tag Keys (comma separated)
CURRENT_MONTH	true / false for if report does current partial month
DAY_MONTH	When to schedule a run. 6, for the 6th by default
TAG_KEY	Provide tag key e.g. Name
TAG_VALUE_FILTER	Provide tag value to filter e.g. Prod*
LAST_MONTH_ONLY	Specify true if you wish to generate for only last month

And then run sh deploy.sh

Deploy Manually (Lambda Console)

1. Create a lambda function (python 3.8 runtime), and update the code to the contents of src/lambda.py
2. Create a lambda IAM execution role with ce:, ses:, s3:, organizations:ListAccounts
3. Configure the dependency layer: arn:aws:lambda:us-east-1:749981256976:layer:CostExplorerReportLayer:1
4. Update ENV Variables in Lambda console
   • Details in table above.
5. Create a trigger (CloudWatch Event)

Running / Testing

Once the Lambda is created, find it in the AWS Lambda console. You can create ANY test event (as the event content is ignored), and hit the test button for a manual run.

https://docs.aws.amazon.com/lambda/latest/dg/tutorial-scheduled-events-test-function.html

Building the Lambda Layer (Optional, for if you want to build your own AWS Lambda layer for use with the script)

Run build.sh to build a new AWS lambda layer with the required Python libraries. This requires Docker, as it builds the package in an Amazon Linux container.

sh build.sh

Customise the report

Edit the main_handler segment of src/lambda.py

def main_handler(event=None, context=None): 
    costexplorer = CostExplorer(CurrentMonth=False)
    #Default addReport has filter to remove Support / Credits / Refunds / UpfrontRI

aws-cost-explorer-report's Issues

Version 1.1.1 of urllib3 no longer supported error

I tried to run this today and got the following error:

{
  "errorMessage": "Unable to import module 'lambda': urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with 'OpenSSL 1.0.2k-fips  26 Jan 2017'. See: https://github.com/urllib3/urllib3/issues/2168",
  "errorType": "Runtime.ImportModuleError",
  "stackTrace": []
}

I would assume this is happening to anyone using this repo (which is great, by the way), because this is no longer supported (from: urllib3/urllib3#2168):

• Version 1.1.1 will be supported until 2023-09-11 (LTS)

List all services by User created Resource Tags

Hey @davfaulk can you also tell me how to list all services by resource tags?
I'm getting this error:
botocore.exceptions.ClientError: An error occurred (AccessDeniedException) when calling the GetTagValues operation: User: arn:aws:sts::678258727640:assumed-role/aws-cost-explorer-report-CostExplorerReportLambdaI-129HLOI5OJI1V/CostExplorerReportLambda is not authorized to perform: tag:GetTagValuesTotal chart

Wrote this piece of code:

Not able to get the emailable report even after successful cloudformation deployment

Hi team,

I am not able to get the emailable report even after successful cloud formation deployment.

Steps:
Updated the deploy.sh file.

export BUCKET=test-awsbilling-cost
export SES_TO=[email protected] -- verified from SES
export SES_FROM=[email protected] -- verified from SES

Please suggest the steps.

Unable to set the start date older than +3

I am getting the below error

I am setting the start date to

self.start = (datetime.date.today() - relativedelta(months=+4)).replace(day=1)

if i make it +3 the report gets generated , wanted to know how to fix the error

issue easy deploy

I always received this message (us-east-1):

"Your access has been denied by S3, please make sure your request credentials have permission to GetObject for aws-cost-explorer-report-bin/lambda.zip. S3 Error Code: AccessDenied. S3 Error Message: Access Denied (Service: AWSLambdaInternal; Status Code: 403; Error Code: AccessDeniedException; Request ID: 87e94822-4462-4241-a082-dabe4f05cb70; Proxy: null)"

Did I have to create previosly an S3 with specific permission?

deploy.sh does not work

The original file does not work if the bin folder does not exist (bin folder is not in the repo).

xxx:aws-cost-explorer-report javy$ ./deploy.sh
lambda.zip not found! Downloading one we prepared earlier
wget: bin/lambda.zip: No such file or directory

Solution would be to use curl instead:

curl https://s3.amazonaws.com/aws-cost-explorer-report-bin/lambda.zip --create-dirs -o bin/lambda.zip

Also L21-L23: https://github.com/aws-samples/aws-cost-explorer-report/blob/master/deploy.sh#L21-L23 can be omitted. The lambda.py is already in the deployment package it's added during build

I am getting below Validation exception error while running this lambda function (Python 3.6 runtime).
Please advise how can fix the same?

More options / doco aroung using non-default awscli credentials

Currently uses default credential (or ENV VARS).
Should look at least at clear communication of how this works.. OR ideally deploy.sh or similar supporting --profile or similar.

Numpy

lambda using your arn causes numpy issue.

Doesn't work when run from linked accounts

First of all, thanks for the code. I am looking for a cost & usage report for my linked account, I know aws doesn't support such reports for linked accounts, that is why I am looking for some kind of in house python code. I thought of working out the getAccounts module to change it use only my account ID. But doesn't seem to work.

Install private repo from git

build.sh does not work, in case requirements.txt has referenced a private repo from git.
In this case, we need to add git credentials or ssh, in order for this to work.

deploy.sh script expects artifacts from author's local machine

line 21 of deploy.sh expects something that is local to the computer that belongs to the author of this utility. I think it's easy to fix but noting here before I get into debugging. Likely will follow up with a PR.

update There is also the AWS account ID of @davfaulk which was added on 2019-06-13 and not removed. It appears the ARN of the dependency layer doesn't have public readable permissions. I'm getting a 403 for arn:aws:lambda:us-east-1:749981256976:layer:aws-cost-explorer-report:1

RI Recommendations per linked account

Currently not supported in the console, would be great to filter recommendations by linked account

Default reports for last day of previous month from run date

At present the default behaviour is for the reports using the last day of current month,

Billing is generally finalised around the 5th of the month however we should not need the current partial month when generating the reports as this will always show as a cost delta reduction

we will need to offset the data culation in lambda.py to be last month to give a more accurate representation

Alternate zip storage?

Would it be possible to shove the zip file into something that isn't git (say, an S3 bucket / git-lfs / etc)? Right now the repo is 61MB and growing with every new zip file regeneration.

TAG_KEY and TAG_VALUE_FILTER are mentioned in the setup instructions, but not in deploy.sh

Are they residual from a previous version? If not, what are they used for?

AWS account aliases

Is it possible to have the report created using the account aliases rather than the account name? I've tried working this in the paginator but whenever I make a change in there the report will just return the account ID.

Excel Charts only support up to 255 series

User report of: "/var/task/./vendored/xlsxwriter/chart.py:134: UserWarning: The maximum number of series that can be added to an Excel Chart is 255

Need to look at combining 255th + rows into "Others" potentially. Or better ordering of data to not lose key series.

Prerequisites to run this tool

Thank you for sharing this useful tool.

I tried this tool on my new account and works great. But I had 2 minor issues while running on lambda for the first time.
So just for sharing. It would be great if it mentioned at 'prerequisite' section.

1. AWS organizations should be enabled.
2. Cost explorer should be enabled.

Cost Tags not separating

With Cost tags in the deploy file, tabs are generated but show the full cost for all of the services, not just the tagged resources.

How to deploy the aws-cost-explorer-report on AWS?

Description

I create the lambda function on the Python 3.6 platform and the IAM for the cost-explorer-report lambda functions. I also tag the services for cost-explorer-report lambda functions.
I hope I can obtain all of regions cost explorer.

Deploying steps:

1. Create an IAM policy and role.
2. Create a lambda function and copy lambda.py source code on my lambda function.
3. Try to do a lambda function test.

Result: Step 3 shows the error messages that are "Can't find out the pandas."

Question part:

Q1. Did you import the pandas library of the python on lambda functions?
Q2. Could you tell me the deploying cost-explorer-report lambda guide?
(I hope it has more detail information. I don't want to use the cloudformation to build.)

IAM policy

IAM policy:
{ "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Allow", "Action": [ "sns:Publish", "aws-portal:ViewPaymentMethods", "aws-portal:ViewAccount", "aws-portal:ViewBilling", "aws-portal:ViewUsage" ], "Resource": "*" }, { "Sid": "VisualEditor1", "Effect": "Allow", "Action": "logs:*", "Resource": "arn:aws:logs:*:*:*" } ] }

Data Shaping to Tall and Skinny

This project is fantastic, thank you!

I prefer to work with pandas dataframes over Excel. Cost Explorer itself - and this project - use a wide data format. I prefer to work with relational data, with ("Index", "TimePeriod","CostAmount") as the column headers, and the rows containing tuples such as [(0, "2019-01-01", 272.11022), (1, "2019-02-01", 271.292)].

Currently I have to "melt" the dataframe to transpose (unpivot) it from wide and shallow to tall and skinny.

Have you considered using a data-science friendly data shape? Would you like a PR submitted or is this on a roadmap?

Costs for Services for linked acounts

it does not work to get the costs for services for each individual accounts, not for all accounts

Enhancement Request: Auto Adjust and Format Cells

Is there any way in the code to get the spreadsheet columns all to adjust automatically when generating it? Also to have the cells that contain dollar amounts to be formatted with $ ?

SES configuration

I tried to use SES configuration to report. Even if it gives us 200 response code inside the lambda function for sending email part I could not receive any email. In the aws "ses" part my email address is also verified. Are there any extra configuration for using sending email?

Need Windows friendly deployment method

Current deploy method options are:

1. deploy.sh
2. Manually change SAM template and use from AWS CLI
3. Manually deploy the lambda

A more friendly Windows deployment method is desirable.
