What is the purpose of Zabbix agents in server monitoring?
The purpose of Zabbix agents in server monitoring is to collect data from the target server and send it to the Zabbix server for further analysis and monitoring.
The agents installed on the target servers actively monitor various system parameters such as CPU usage, memory utilization, network statistics, and disk space. They are responsible for gathering this data at regular intervals and forwarding it to the Zabbix server for processing.
Zabbix agents also play a crucial role in executing remote commands on the monitored servers, allowing administrators to perform tasks like restarting services, managing configurations, or troubleshooting issues remotely.
Overall, Zabbix agents enable comprehensive monitoring and management of various server metrics, enabling administrators to identify potential issues and take necessary actions proactively.
