Prometheus vs. Zabbix

January 9, 2019

What is Prometheus?


Prometheus is an open-source monitoring system built around a time series database, able to receive data and store it, in addition to supporting queries, graphs, and in-built alerting. Connecting to target endpoints to request metrics via HTTP, Prometheus provides a multi-dimensional data model wherein metrics can be defined by names and/or tags which identify them as part of a unique time series. Open-source Prometheus metrics have a default retention of 15 days, though with Hosted Prometheus by MetricFire data can be stored for up to 2 years. The Prometheus query language (PromQL) can then be used to explore metrics and draw simple graphs.

What is Zabbix?

Zabbix is an open-source monitoring tool for IT systems such as networks, servers, virtual machines, and cloud services. Zabbix can collect metrics, detect problems, visualize, notify, and send notifications. There is also functionality for app monitoring. Zabbix is designed for for small scale environments, from anywhere to a few devices to a thousand. Zabbix also allows for easy distributed monitoring, where you can keep connection and open port count low. Some large scale installations have been made, but they require a lot of optimization. Zabbix doesn’t store data itself, but it can use a broad range of databases. Zabbix’s backend is written in C and the web frontend is in PHP. Zabbix as a Service is available through the Zabbix website, and there are 5 stages for pricing.
