AWS DBR parser

Author: Rafael M. Koike

AWS ProServe

This script was created to support automatic parsing of Detailed Billing Records (DBR) to JSON format and send these documents directly to ElasticSearch or save it in a JSON file. It’s based on AWS boto3, Elasticsearch Python API and click CLI creation kit.

Instalation Instructions

This project isn’t on PyPI yet. For installation you will need to clone this repository and use setup.py script to install it. For requirements see the requirements/base.txt file. Clone this repository and install using plain python and the setup.py script. For example:

• This option just install the dbrparser but maybe you can use the job.sh from the repository to schedule the process in your cronjob

$ pip install git+https://github.com/awslabs/aws-detailed-billing-parser.git

• This option clone the repository from git to your instance and install

$ git clone https://github.com/awslabs/aws-detailed-billing-parser.git
$ cd aws-detailed-billing-parser
$ python setup.py install

Executing

Once installed run dbrparser CLI with --help option:

$ dbrparser --help

Running Tests

Tests still need to be written. But we have already introduced py.test, tox for test run automation and flake8 to check quality and style of the code. There are nice stubs for testing the CLI command line. All you have to do is install tox and issue tox in the command line.

TODO (Features to incorporate in the dbrparser)

• Unzip (Extract the DBR from zip file);
• S3 (Copy the source file from S3 bucket to local folder to process);
• To be compatible with AWS Lambda the parser must run in max 5 min and depending on the size of the file this won’t be possible, so we will probably need to include a new option like, say --max-rows and every call to lambda will process a maximum of 10000 rows for exemple. This may give us a previsibility that lambda will work in the correct timeframe;
• Write more tests.

Changes

Version 0.5.0 - 2016-10-11

• Included Dynamic Template to new document fields be Not Analyzed
• Included support to AWS Signed V4 requests. If you are running the program from an EC2 instance or from a computer that has installed aws cli and configured with the correct credentials you just need to include--awsauth parameter
• Changed the split_keys function to pre_process and include extra information based on the UsageType field Now you have:
  • UsageItem with the options:
    • On-Demand
    • Reserved Instance
    • Spot Instance
  • InstanceType with only the instance name extracted from the UsageType

Version 0.4.1 - 2016-08-31

• Changed requirements to support newer versions of boto3. (Due to some other softwares that need version 1.3.1 or higher, dbrparser is conflicting with other softwares)

Version 0.4.1 - 2016-05-11

• Bugfix of timeout when sending by bulk (Increased to 30 seconds)

Version 0.4.0 - 2016-03-27

• Project was completely restructured in order to create a proper Python package called awsdbrparser and the CLI name dbrparser;
• In the CLI side, argparse was dropped in favor of Armin Ronacher’s click, allowing a better and easier CLI implementation;
• Introduced option ‘–quiet’ for those who intent to schedule DBR parsing via cron jobs, for example;
• Introduced option ‘–fail-fast’ which will stop parsing execution in case of an expected parse error or other component error;
• Dropped own implementation of progress bar in favor of click’s progress bar, which includes a nice ETA (estimated time for acomplishment) calculation;
• When used as a library, parser execution can be parametrized through awsdbrparser.config.Config class instance.
• Entire code was reviewed to match PEP8 compliance (with fewer exceptions) through flake8.

Version 0.3 - 2016-02-12

• Added incremental updates with --check parameter (Now you can update the same file to the index without need to delete the index and reprocess the entirely file again);
• Compatible with Elasticsearch 2.1 and above (Removed the _timestamp from mapping that has been deprecated from 2.0 and above);
• Included elapsed time to evaluate the time to process the file.

Version 0.2 - 2015-10-26

• Filter of control messages (Stop the error in the end of processing);
• Verbose output of the processing;
• Progress bar;
• Output options (to file or directly to Elasticsearch);
• Elasticsearch mapping.

version 0.1 - 2015-10-17

• Initial version.
