What is the Zabbix Agent?
The Zabbix Agent is a lightweight and efficient application installed on a target system to actively monitor local resources and applications. It collects a vast amount of data, such as CPU load, memory usage, disk space, and network activity, and reports it back to a centralized Zabbix server. This provides administrators with a comprehensive, real-time view of the health and performance of their entire IT infrastructure, from servers and virtual machines to network devices and applications. It is the cornerstone of a robust monitoring strategy.
