Chapter 6. Using the Nagios Plugins
The previous chapters discussed the basic configuration of host and service checking along with the description of the web interface. Nagios can be set up to check if your services are up and running. This chapter describes how these checks work in more detail. It also introduces some of the Nagios plugins that are developed as a part of Nagios and as a part of the Nagios Plugins project.
The strength of Nagios comes from its ability to monitor servers and services they offer in a large number of ways. What's more interesting is that all of these ways make sure that your services are provided as functional, are external plugins, and work in quite an easy way. Many of these are even shipped with Nagios, as we mentioned in Chapter 2, Installing Nagios 4, and Chapter 3, Configuring Nagios. Therefore, it is possible to either use the existing plugins or write your own.
In this chapter, you will learn the checks that can be made using the Nagios...
