Technical requirements
We are going to need several new Linux hosts for this chapter, as we'll be building them as Zabbix proxies.
Set up two proxies by installing CentOS (or your preferred Linux distribution) on the following two new hosts:
lar-book-proxy-passive
lar-book-proxy-active
You'll also need the Zabbix server, with at least one monitored host. We'll be using the following new host with a Zabbix agent installed:
lar-book-agent-by-proxy
