How does Zabbix collect and monitor data?

Zabbix is an open-source network monitoring tool that collects and monitors data through Zabbix Agent and Zabbix Proxy. Below are the steps for collecting and monitoring data with Zabbix.

1. Install Zabbix Agent or Zabbix Proxy: Start by installing Zabbix Agent or Zabbix Proxy on the host that needs monitoring. The Agent is used for active data collection, while the Proxy is used for proxy data collection.
2. Set up Zabbix Agent or Zabbix Proxy by configuring monitoring parameters such as the monitored host, port, and metrics in the configuration file of the Agent or Proxy.
3. Adding a host in Zabbix Server involves adding the host that needs to be monitored, setting the IP address, hostname, and type of Agent or Proxy for the host.
4. Create monitoring items: Create monitoring items in the Zabbix Server to define the metrics that need to be monitored, such as CPU utilization, memory usage, and disk space.
5. Create a trigger: Create a trigger in the Zabbix Server, which will define when to trigger an alert when a monitored item reaches a certain threshold.
6. Setting up an action: create an action in the Zabbix Server to define the operations to be executed when a trigger is activated, such as sending emails or SMS messages.
7. Check monitoring data: You can view monitoring data, including the values of monitoring items and the status of triggers, on the monitoring page of the Zabbix Server.

By following the above steps, it is possible to collect and monitor data from the host, quickly identify and resolve issues, and ensure the stability and reliability of the system.
