AWS CloudTrail Processing Library

The AWS CloudTrail Processing Library is a Java client library that makes it easy to build an application that reads and processes CloudTrail log files in a fault tolerant and highly scalable manner.

• CloudTrail Product Page
• CloudTrail Forum
• Github Issues

Features

• Provides functionality to continuously download CloudTrail log files in a fault tolerant and scalable manner.
• Serializes the events in JSON format to Plain Old Java Objects (POJO).
• Provides interfaces to implement your own business logic for selecting which events to process, processing events, handling errors, and handling log processing status updates.

Getting Started

Minimum Requirements

• AWS Java SDK 1.12.1: To use the AWS CloudTrail Processing Library, you'll need the AWS Java SDK.
• Java 1.8: The AWS CloudTrail Processing Library requires Java 1.8 (Java SE 8) or later.

Documentation

To learn how to use the AWS CloudTrail Processing Library to build a CloudTrail log processor in Java, read the documentation:

• Using the CloudTrail Processing Library in the AWS CloudTrail User Guide.
• AWS CloudTrail Processing Library Reference

Building From Source

After you've downloaded the code from GitHub, you can build it using Apache Maven. To disable GPG signing in the build, use this command:

mvn clean install -Dgpg.skip=true
