What it is

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.
