No history for master item
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.
