The standard Zabbix data flow is composed of several actors that send data to our Zabbix server. Of all the sources that can send data to our Zabbix server, we can identify three main data sources:
Zabbix agent
Zabbix sender
Other agents (external scripts or components built in house)
The other agents represented in the next diagram can be of two main types:
Custom and/or third-party agents
Zabbix proxy
As the diagram displays the data that gets acquired from many different sources in the form of items. At the end of the diagram, you see the GUI, which practically represents the users connected and the database that is the place where all the values are stored.
In the next section, we will dive deep into the Zabbix proxies' data flow.
