Chapter 7. Scaling Nagios
The load on a well-built monitoring system will inevitably outgrow its hardware. Good monitoring systems are too useful to ignore, and service by service, host by host, you will eventually find yourself in the unenviable position of having to migrate everything to a bigger, or at least beefier, server. But before you start backing up your Nagios config files, consider taking a more future-proof route. In this chapter, I explore a few options for scaling your existing Nagios install using distributed architectures—that is, spreading the monitoring load across more than one Nagios server.
Tuning, Optimization, and Some Building Blocks
Before we get into the distributed solutions, I should mention that there’s quite a ...
