IT and network administrators, DevOps teams, and MSPs who need to monitor servers, networks, cloud, applications, and services at enterprise scale.
An open-source monitoring platform with metrics collection, real-time alerting, and customizable dashboards. It includes auto-discovery of network devices and hosts, template-based configuration for common systems, and flexible triggers for problem detection. Data can be gathered via agents, SNMP, IPMI, JMX, or custom scripts, with historical data storage for trend analysis.
You deploy the Zabbix server (self-hosted or via Zabbix Cloud) and install agents or configure agentless polling on the hosts and devices you want to monitor. Zabbix collects metrics on a schedule, evaluates them against configurable triggers, and raises alerts or dashboard visualizations when thresholds are breached.
