Zabbix is the "all-seeing eye" that gathers data from our environment. The main concept and function of Zabbix is data gathering in the far corner. With this understanding, we need to take care of some basic things to help Zabbix achieve its target.
In the previous chapter, we talked about a scenario where Zabbix plays an important role in any environment. Now we need to think about the possible ways to configure Zabbix so that it can achieve the best performance in our environment.
In this chapter, we'll cover the following topics:
Item types and performance issues
Active items—a forgotten option
Triggers matter a lot
Trends and history storage time
Is the housekeeper a problem?
Caches and buffers
Can default templates be the villains?
DBSyncers—the unknown bottleneck
