Icinga 2

Project2.2K

Monitor network resources, notify users of outages, and generate performance data for reporting.

What you can build

  • Code a converter that reads a CSV of network resources and produces reviewable plain-text Icinga DSL drafts, preserving the original inventory.
  • Build a text-processing tool that takes DSL configuration files and a site/resource inventory, then outputs a report of inventory entries not represented in the files.
  • Write a report generator that takes a CSV of recorded performance values and produces per-resource daily summaries and week-over-week changes.
  • Build a script that transforms an operator-maintained outage log into incident handoff records with affected resources, start and end times, and follow-up fields.
  • Create a planner that takes a site-and-resource map and outputs staged rollout groups and a checklist for operators managing a distributed environment.

Try this prompt

Build a small local tool that reads a CSV inventory of network resources and emits reviewable plain-text Icinga DSL configuration drafts plus a report of missing or malformed input fields. Consult the official configuration documentation rather than guessing DSL constructs. Keep generated drafts separate from live configuration, preserve the original CSV unchanged, and include a sample input, output, and tests for invalid rows.

Get started

  1. Install the server

    Follow the official Icinga 2 installation guide for your operating system: https://icinga.com/docs/icinga2/latest/doc/02-installation/.

  2. Learn the monitoring workflow

    Review Monitoring Basics before adapting checks for your environment: https://icinga.com/docs/icinga2/latest/doc/03-monitoring-basics/.

  3. Choose a configuration approach

    Use the configuration guide to learn the documented options, including plain-text Icinga DSL: https://icinga.com/docs/icinga2/latest/doc/04-configuration/.

License & notes

GPL-3.0Icinga 2 is GPL-3.0-or-later software, with an OpenSSL linking exception described in the README; check the notices for the version you use. Commercial use is permitted. GPL obligations apply when conveying copies or modified versions; private modification and use alone do not require publishing source, and network interaction alone is not conveying under GPLv3. Hosting, compute, and access to monitored resources may incur costs; no amounts are provided. No model or paid API costs are documented.

  • Icinga 2 is the monitoring server; the README says Icinga Web 2 is required on top in the Icinga Stack.
  • Self-hosting requires compute and access to monitored resources; the supplied evidence does not specify resource requirements or costs.
  • Verify DSL syntax, integrations, and data formats in the official documentation before building against them; the supplied README does not detail their interfaces.
