Study Notes

Zabbix Proxy Communication Overview

Zabbix proxy can work in active or passive mode, controlling update intervals in different ways.
Active proxy connects and sends configuration and data to the server at specified intervals.
Passive proxy can't perform configuration cache reloading and ignores certain runtime commands.
When creating or configuring a proxy, options include specifying encryption parameters.
The proxy list in the frontend displays proxy mode, encryption, compression, and last seen information.
All data sent by a proxy is compressed, improving data transfer speed without impacting CPU and memory.
The health of all Zabbix proxies must be monitored using internal items for the Zabbix server, adjusting configuration if necessary.
The built-in "Zabbix proxy health" template monitors proxy internal metrics and ensures the server notices an active proxy missing.
Adding a regular host to monitor the proxy involves linking to the "Zabbix proxy health" template and checking the latest data, graphs, and screens.
Zabbix proxy is a data collector that doesn't calculate triggers, process and correlate events, or send alerts, but supports other functionalities.
All data on Zabbix server is collected only using trappers or proxy pollers, with the load distributed by adding more proxies and preprocessing done by proxies.
Zabbix proxy caches data if the Zabbix server is unreachable, and only a single communication port is needed between the Zabbix server and proxy.
