Future-proof all-in-one monitoring

Monitor all assets in your IT infrastructure. Servers, switches, firewalls, storage, application containers, or cloud – all covered by Checkmk. No matter how your IT environment looks today or whether it changes in the future, all you need to gain control of your entire hybrid IT infrastructure is Checkmk.

Flexible and effortless

Checkmk gives you high flexibility. Monitor your systems with native agents for Linux or Windows, agentless via HTTP or SNMP TCP/UDP, or connect your monitoring via APIs to any application. With the rule-based approach, you can automatically enforce monitoring policies for all devices at a particular location, or any device group.

Automated monitoring

Thanks to automated configuration and monitoring operations via the Checkmk API, a centralized agent management feature, or the dynamic host configuration, Checkmk takes a lot of work off your hands, even when monitoring dynamic environments, such as Docker or Kubernetes.

Smart alerting

Checkmk comes with intelligent notifications to ensure that you don’t get drowned in alerts, and only receive relevant notifications. Benefit from flexible notification and escalation options integrated with popular notification tools such as Slack, PagerDuty, SIGN4L, VictorOps, or Jira.
