Zabbix

Overview

Zabbix is an open-source monitoring platform for networks, servers, cloud services and applications. Since version 7.0 it has been licensed under the GNU Affero General Public License v3; versions up to 6.4 used GPLv2^[13]. The software is free to use, modify and distribute, and Zabbix asks, but does not require, commercial users to support development by buying technical support^[13].

Zabbix monitors devices both with its own agents and agentlessly over network protocols such as SNMP, using templates and trigger expressions for alerting. Its flexibility is a strength for experienced teams and a challenge for newcomers, since templates, triggers and dashboards require configuration.

For organisations that do not want to host the platform, Zabbix Cloud is priced by new values per second (NVPS): Nano (50 NVPS) starts at US$50 per month, Medium (1,000 NVPS) at US$750 and 2xLarge (10,000 NVPS) at US$5,000, with 10% off for annual billing and 10 GB of storage included in the entry plan^[14]. The cloud trial lasts only five days^[14]. Commercial support subscriptions are sold separately.
