What it is

Icinga monitors infrastructure and applications, collecting and analyzing data to help teams identify and resolve errors. It covers servers, applications, and network devices across on-premises and cloud environments. Dashboards, filtered and grouped views, and notifications provide visibility, while troubleshooting entry points support root-cause investigation. Teams can extend monitoring with clustering, custom checks, plugins, configurable 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; the pricing FAQ describes a REST API for custom integrations. Icinga says node communication uses TLS/SSL and provides certificate tools. It can monitor certificates, alert as they approach expiry, and verify self-signed certificates using a custom trust store. The product is self-hosted and supports Linux and Windows; official packages cover several Linux distributions and Windows, with some requiring a paid subscription. The free, open source edition includes unlimited hosts and services. Paid support and subscriptions are also available, with support starting at $15,000 a year.
