Let's conclude this chapter by digging into the configuration files of the Zabbix agent and server, and examining each parameter in them. We'll start with the agent configuration file and discuss the ways in which common parameters apply to other daemons. We'll skip the proxy configuration file, as the common parameters will be discussed by then, and the proxy-specific parameters were discussed in Chapter 17, Using Proxies to Monitor Remote Locations. We'll also skip all the parameters that start with TLS, as those are related to Zabbix daemon traffic encryption, and we discussed that in Chapter 18, Encrypting Zabbix Traffic.

We'll look at the parameters in the order in which they appear in the default example configuration files; no other meaning should be derived from the ordering here.

While reading the following descriptions, it's suggested to have the corresponding configuration file open. It'll allow you to verify that the parameters are the same in your version of Zabbix. Make sure to read the comments next to each parameter; they might show that some parameters have changed since the time of writing this. In general, when in doubt, read the comments in the configuration files. The Zabbix team tries really hard to make them both short and maximally relevant and helpful.
