Icinga 2 is the core monitoring server of the Icinga stack, checking availability of network resources, sending outage notifications, and generating performance data. It features a powerful configuration DSL, a REST API, and supports scalable distributed monitoring across multiple locations.

Use cases

• monitor server and network infrastructure uptime
• set up alerting when services go down
• build a distributed monitoring cluster across data centers
• export performance metrics to graphite or influxdb
• self-hosted nagios alternative with a rest api
• monitor hybrid cloud and on-prem environments

When to choose

• you need scalable, self-hosted infrastructure monitoring with notifications
• you want a REST API and a flexible configuration language for automation
• you run large or multi-site environments needing distributed monitoring

When to avoid

• you only want lightweight application/APM tracing rather than host and service checks
• you need a turnkey UI without deploying the separate Icinga Web 2 component
• you prefer a fully managed SaaS monitoring solution
