Written by Ganglia designers and maintainers, this book shows you how to collect and visualize metrics from clusters, grids, and cloud infrastructures at any scale. Want to track CPU utilization from 50,000 hosts every ten seconds? Ganglia is just the tool you need, once you know how its main components work together. This hands-on book helps experienced system administrators take advantage of Ganglia 3.x. Learn how to extend the base set of metrics you collect, fetch current values, see aggregate views of metrics, and observe time-series trends in your data. You’ll also examine real-world case studies of Ganglia installs that feature challenging monitoring requirements.
My 2 reasons for 5 stars rating: 1) The most complete reference of ganglia except the ganglia code itself. 2) provide a number of customer cases on how ganglia is adopted. you hardly get them out of this book.
Even if you do not use Ganglia to monitor, you will like and learn a lot with this book. Very easy to read, the subjects are so well writen in a simply way. The reading just flows.
