Zabbix
Zabbix is an open-source monitoring software tool for tracking the performance and availability of IT infrastructure components, such as servers, networks, applications, and services. It collects and analyzes metrics in real-time, provides alerting, visualization, and reporting features to help organizations ensure system reliability and troubleshoot issues proactively.
Developers should learn Zabbix when working in DevOps, SRE, or system administration roles to monitor production environments, detect anomalies, and automate incident responses. It is particularly useful for large-scale distributed systems, cloud infrastructure, and applications requiring high availability, as it supports agent-based and agentless monitoring, custom metrics, and integrations with tools like Slack or PagerDuty.
