Overview of this book

Discover how to perform a complete forensic investigation of large-scale Hadoop clusters using the same tools and techniques employed by forensic experts. This book begins by taking you through the process of forensic investigation and the pitfalls to avoid. It will walk you through Hadoop’s internals and architecture, and you will discover what types of information Hadoop stores and how to access that data. You will learn to identify Big Data evidence using techniques to survey a live system and interview witnesses. After setting up your own Hadoop system, you will collect evidence using techniques such as forensic imaging and application-based extractions. You will analyze Hadoop evidence using advanced tools and techniques to uncover events and statistical information. Finally, data visualization and evidence presentation techniques are covered to help you properly communicate your findings to any audience.

Introduction


Amazon CloudWatch is AWS's monitoring service. It can be used to monitor your applications and AWS resources. AWS CloudWatch works with all key AWS services including EC2, RDS, DynamoDB, Elastic MapReduce, Kinesis, CloudSearch, and so on. CloudWatch provides several out-of-the-box metrics such as CPU utilization, network utilization, and disk I/O metrics from EC2 instances. However, you can also collect custom metrics from your applications.

AWS Management Console can be used to view, search, and graph the metrics data loaded by Amazon CloudWatch. CloudWatch stores data as a series of time stamped data points.

One of most common use cases for CloudWatch is to use it to set alarms and take actions, based on the metrics. For example, you can stop, terminate, recover, or reboot an EC2 instance in response to a CloudWatch alarm being raised. CloudWatch Logs lets you collect your application, system, and custom log files into AWS CloudWatch Logs for analysis.
