Summary

Icinga monitors infrastructure and applications, collecting and analyzing data to help teams identify and resolve errors. It covers servers, applications, and network devices, including on-premises and cloud servers. Dashboards, filtered and grouped views, notifications, and troubleshooting entry points support investigation of possible root causes. Teams can use clustering, custom checks, plugins, configurable monitoring logic, and distributed environments. Listed integrations include Grafana, InfluxDB, Elastic, Graylog, Ansible, Puppet, Terraform, AWS, Azure, Jira, PagerDuty, and ServiceNow. The free edition supports API automation and Git-based workflows, and the pricing FAQ describes a REST API for custom integrations. Icinga says communication between nodes uses TLS/SSL and provides certificate tools. It can also monitor certificates, alert as they near expiry, and verify self-signed certificates with a custom trust store. Icinga is self-hosted and available for Linux and Windows. Its free edition has unlimited hosts and services; paid support and subscriptions are also listed.
