Centreon vs Prometheus Node Exporter

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.

Prometheus Node Exporter exposes hardware and operating-system metrics from *NIX kernels for Prometheus. Written in Go, it uses pluggable collectors, with default coverage for CPU, disk I/O, filesystem, memory, and network metrics where the operating system supports them. Command-line flags enable or disable collectors, and some collectors accept include or exclude filters. The exporter listens on HTTP port 9100 by default. Documentation covers Linux distribution packages, an Ansible community role, and container deployment. Containerized monitoring requires host namespace access and suitable mounts; some systems also need an extra capability for the timex collector. Certain collectors are off by default because they can have high cardinality, take longer, or consume host resources. The project is Apache 2 licensed and free, with no paid plans listed. Windows users are directed to Windows Exporter.
