The IT monitoring platform.
Scalable. Automated. Extensible.
Gain a complete view of your entire IT infrastructure: from public cloud providers, to your data centers, across servers, networks, containers, and more. Checkmk enables ITOps and DevOps teams to run your IT at peak performance.
The heart of the Checkmk platform is the High Performance Core, designed to scale up to millions of services monitored while still retaining a small footprint.
Its REST API and many automations, such as the auto-registration of hosts, take manual work off your IT team’s shoulders.
Checkmk not only monitors everything that powers your business, but also keeps it secure, thanks to granular access control, encryption, and 2FA.
