Overview of this book

We start with the perplexing task of extracting value from huge amounts of barely intelligible data. The data takes a convoluted route just to be on the servers for analysis, but insights can emerge through visualization and statistical modeling techniques. You will learn to extract value from IoT big data using multiple analytic techniques. Next we review how IoT devices generate data and how the information travels over networks. You’ll get to know strategies to collect and store the data to optimize the potential for analytics, and strategies to handle data quality concerns. Cloud resources are a great match for IoT analytics, so Amazon Web Services, Microsoft Azure, and PTC ThingWorx are reviewed in detail next. Geospatial analytics is then introduced as a way to leverage location information. Combining IoT data with environmental data is also discussed as a way to enhance predictive capability. We’ll also review the economics of IoT analytics and you’ll discover ways to optimize business value. By the end of the book, you’ll know how to handle scale for both data storage and analytics, how Apache Spark can be leveraged to handle scalability, and how R and Python can be used for analytic modeling.

Preface

Creating and visualizing alerts


IoT data is inherently noisy. There are often cases of invalid and missing values. This requires constant vigilance to identify and correct data issues when they occur. The correction could then be handled in the transformation of the raw data or in the software and design of the device.

Either way, the faster an issue is detected, the quicker it can be resolved. For IoT data, consider bad data as lost money that can rarely be recovered. Minimize the loss by identifying and correcting issues quickly.

Dashboards can also be created for this purpose by following the same process we introduced in this chapter. Think about what you want to watch out for and set up an alert view to identify it for you.

Alert principles

There are some principles to follow when designing an alert system, even a simple one that will be part of a dashboard:

  • Balance alert sensitivity to minimize false positives: People will learn quickly to ignore alerts if they rarely identify an actual...
