Both Zabbix and Prometheus are highly popular monitoring systems. They share many similarities but also have some distinct differences. Here are some key points of comparison between Zabbix and Prometheus monitoring:

1. Data Model and Query Language

Prometheus utilizes a query language called PromQL to query and process time-series data. PromQL supports various data models and query functionalities, including metrics, labels, and aggregation functions. Zabbix, on the other hand, employs its own data model and query language, encompassing concepts such as items, triggers, and actions.

2. Storage Method

Prometheus uses a time-series database known as TSDB to store time-series data. TSDB employs a write-ahead log (WAL) to ensure data reliability. In contrast, Zabbix utilizes a relational database for data storage.

3. Automation and Configuration Management

Prometheus possesses automation and auto-configuration capabilities, enabling it to automatically discover services and metrics and monitor them. Zabbix also offers similar functionalities but requires manual configuration.

4. Visualization and Alerting

Both Zabbix and Prometheus support visualization and alerting features. Zabbix provides a web-based front-end interface for viewing monitoring data and setting up alerts. Prometheus is often used in conjunction with tools like Grafana to achieve more advanced visualization and alerting capabilities.

5. Performance and Scalability

Prometheus demonstrates excellent performance and scalability, capable of handling large-scale time-series data. Zabbix also exhibits good performance and scalability but may require more resources and configuration for large-scale monitoring.

Zabbix is more suitable for monitoring local computers, whereas Prometheus is better suited for monitoring in the popular cloud computing environment nowadays.
