How is data transmission and information display on dashboards implemented in the Zabbix system?

In Zabbix, data is collected from agents or other sources (e.g., SNMP, IPMI) and sent to the Zabbix server. Data transfer occurs via the Zabbix Agent protocol or through proxy servers that aggregate data.

Main stages:

1. Data collection — agents on hosts collect metrics (CPU, memory, network, etc.) and send them to the server.
2. Storage — the Zabbix server saves data in a database.
3. Processing and triggers — the server analyzes data, checks trigger conditions.
4. Display — data is visualized on dashboards and graphs in the Zabbix web interface.

Dashboards are built based on stored data and can include graphs, tables, maps, and widgets showing current status and metric history. Users can customize the display, filters, and time periods for monitoring.
