About Checkmk
Checkmk is a monitoring and observability platform for hybrid environments. It finds the systems you run in the cloud and on premises, and monitors them from one place.
What it does
Checkmk discovers hosts, services, containers and applications, then tracks their health and resource use. An Explain feature turns any alert into a short root cause summary with suggested next steps. A read-only server lets your own tools query live monitoring data, with role-based access control in place.
Key features
- Automatic discovery of cloud, server, network and container systems
- More than 2,000 integrations
- Explain feature that summarizes an alert
- Read-only server for connecting your tools to live data
- Deployment support for air-gapped networks
Who it's for
IT operations teams and platform teams that run mixed infrastructure. Organizations with strict security rules, including air-gapped sites, will find the deployment options relevant.
Pricing and good to know
Checkmk is licensed under GPL-2.0 on GitHub, and a free trial is offered on the site. Pricing is based on hosts and services, which the vendor describes as predictable. Several editions are available, so compare their features before choosing one.
