Zabbix is fully open source with no per-device fees, monitoring availability, performance and interface traffic across networks and servers. It delivers exceptional value and deep customization, but carries a steep learning curve and leans on the team to build out maps and alert logic.
Pros & cons
Pros
- Free and open source with no per-device licensing
- Highly customizable and powerful once configured
Cons
- – Steep learning curve and a dated interface in places
- – Fine-tuning alerts takes experience to avoid noise
