Beskrivelse
With Ganglia, you can monitor the performance of several deployment scenarios - but this tool's strength can also be a weakness if you don't know how all its pieces work together. This book shows you how to configure Ganglia to monitor clusters, grids, or cloud infrastructures at very large scales on the order of thousands of machines. Experienced users will get up to speed on the latest Ganglia release (3.x), including several recent features, such as sFlow support and Ganglia's new web frontend. You'll learn how to extend the base set of metrics you collect, fetch current values, see aggregate view of metrics, and look at time-series trends in your data.
