Icinga
Open source infrastructure monitoring for networks, servers, cloud and applications
Icinga is an open source monitoring platform for IT infrastructure, providing a centralized view of servers, networks, cloud, containers, databases, applications, Windows and VMware environments. It helps teams detect issues before they cause outages, reduce alert noise, and manage monitoring configuration through apply rules, custom variables, and dependency visualization.
Core capabilities include infrastructure monitoring, monitoring automation, notifications, metrics and logs, analytics, and cloud monitoring, with native OpenTelemetry export to Prometheus, VictoriaMetrics, and other compatible backends. It supports custom checks, dashboards, API-driven automation, directory services such as Active Directory, high availability clustering, and integrations with DevOps, cloud, and ITSM tools. Modules such as Director extend configuration management.
Icinga is aimed at IT operations teams managing hybrid on-premises and cloud environments, from single instances to enterprise-scale deployments. It is available as a free open source edition, with paid subscriptions covering repositories, modules, and enterprise support, alongside certification, consulting, and training services.
