Icinga ranks #12 of 20 infrastructure monitoring tools in the Infrastructure Monitoring Ledger 2026, with a Ledger Index of 64.2 out of 100. Icinga builds a modular, fully GPL stack with a steady, honest record, but graphs, logs, flows and network config live in other tools buyers must run.

What the Ledger says
Icinga is building a modular, fully GPL monitoring stack around its check engine, with Icinga DB for scale, Director for automation and a new notification service. Its record is steady and honest: small, regular releases, every 2023-2026 promise delivered, and no exploited flaws. The trade-off is that graphs, logs, flows and network configuration all live in other tools, so buyers assemble and run several products.
AI say-do: 2 tracked, 2 delivered GA (Icinga DB, Notifications), 0 dropped; MCP preview shipped as promised. No ML in the product; a community Ollama summarizer does not count.
