A new free eBook has been released about Extending Operations Manager Reporting, it is available for download here.

Introduction

The System Center Operations Manager data warehouse stores many objects, making it
possible to report on performance, availability, configuration, and security. You can use data
collected by Operations Manager for issue tracking, awareness, planning, and forecasting, all of
which are important factors for maintaining and managing your environment. But
understanding what to report on and how to do so is what actually contributes to the stability
of your infrastructure. If you’re not using the data you collect about your environment, you’re
simply wasting space. If you use Operations Manager to monitor your environment, whether
your infrastructure or a public, private, or hybrid cloud, this book is a good resource to help
you understand the basics of reporting and how to build queries and stored procedures for
your reports. It can also help you understand the various elements of Operations Manager
management packs that are used when you create reports.
This book assumes that you have a good understanding of Operations Manager and the
management pack structure required to create custom reports. It also assumes that you have a
good working knowledge of SQL Server and tools like Report Builder, Business Intelligence
Development Suite, and SQL Server Data Tools.
