Chapter 1. Introducing Ganglia
If you’re reading this, odds are you have a problem to solve. I won’t presume to guess the particulars, but I’m willing to bet that the authors of this book have shared your pain at one time or another, so if you’re in need of a monitoring and metrics collection engine, you’ve come to the right place. We created Ganglia for the same reason you’ve picked up this book: we had a problem to solve.
If you’ve looked at other monitoring tools, or have already implemented a few, you’ll find that Ganglia is as powerful as it is conceptually and operationally different from any monitoring system you’re likely to have previously encountered. It runs on every popular OS out there, scales easily to very large networks, and is resilient by design to node failures. In the real world, Ganglia routinely provides near real-time monitoring and performance metrics data for computer networks that are simply too large for more traditional monitoring systems to handle, and it integrates seamlessly with any traditional monitoring systems you may happen to be using.
In this chapter, we’d like to introduce you to Ganglia and help you evaluate whether it’s a good fit for your environment. Because Ganglia is a product of the labor of systems guys—like you—who were trying to solve a problem, our introduction begins with a description of the environment in which Ganglia was born and the problem it was intended to solve.
