Zabbix- The Monitoring Tool

• Zabbix is an open-source software tool to monitor IT infrastructure such as networks, servers, virtual machines, and cloud services. Zabbix collects and displays basic metrics​

• We need to configure Zabbix in Linux and set up the dashboard.​

• Zabbix can play an important role in monitoring IT infrastructure. This is equally true for small organizations with a few servers and for large companies with a multitude of servers.​
