Zabbix is an open source monitoring tool. It is popular for its easy-to-use and pleasing Web GUI that is fully configurable. Zabbix focuses on monitoring and trending functionality. This software is frequently used for monitoring servers and network hardware. One of the highlights of Zabbix is that it can predict trends in your traffic. Zabbix can forecast future behavior based on historical data.
Since it is open source, it has an active user community spread around the world and good documentation. Zabbix gives the freedom to use the open-source solution without vendor lock-ins (including all components).
Zabbix is powerful for SMB networks below 1,000 nodes. Over that, the software can get slower and its performance decreased. Another disadvantage is that it doesn’t include real-time tests and reports.
