Centreon vs Icinga

Centreon is an IT monitoring platform for infrastructure spanning cloud environments and edge systems. It monitors servers, networks, cloud environments, and applications, with more than 700 connectors for areas including infrastructure, security, databases, middleware, and OT systems. Deployment is available as SaaS or self-hosted software. Integrations include ServiceNow, JIRA, GLPi, EasyVista, Microsoft Teams, Slack, Telegram, PagerDuty, and OpsGenie; stream connectors can send metrics and events to Elastic, Kafka, and Splunk. Access controls include fine-grained permissions, SAMLv2 identity-provider integration, and Active Directory and LDAP synchronization. Centreon uses TLS-encrypted communications and supports secure collection through its monitoring agent or poller. The agent monitors Linux and Windows hosts and streams metrics over encrypted gRPC. The core platform is distributed under the Apache license, with GPLv2 applying to some files. The free plan covers up to 100 hosts; paid plans start at €2.27 per host, and Centreon Cloud has a 7-day trial for up to 125 hosts. Centreon Experience Monitoring offers a separate 30-day trial.

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.
