Checkmk vs Prometheus Node Exporter

Checkmk monitors cloud, hybrid, and data center infrastructure, including containers and networks. For web, mail, and database servers, it combines more than 2,000 smart checks with automatic discovery and network mapping. Monitoring can use native agents for Windows, Linux, and other systems, agentless SNMP and TCP/UDP checks, or API-based checks over HTTP/XML, SSH, or TELNET. Cloud coverage includes AWS, Azure, and Google Cloud Platform, with automatic component detection and Quick Setup. One instance can monitor thousands of servers, while distributed monitoring supports horizontal scaling. Community includes more than 2,000 integrations and is intended for smaller environments, scaling to approximately 100 hosts. The software can run on customer hardware or virtualized infrastructure, with Linux distribution packages, Docker, and a Virtual Appliance. The Community plan is free forever and includes community support. The pricing note lists paid plans from €190/mo (annual) and a 30-day trial. Other listed plan prices use USD: Pro is $275 a month, Cloud is $290 a month, and Ultimate is $400 a month. Platforms include API, Linux, macOS, self-hosted, web, and Windows.

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.
