The state-of-the-art IT monitoring platform from Checkmk

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.
In-depth insights with one click
Thanks to over 2,000 vendor-maintained plug-ins, Checkmk automatically detects almost any system and knows which metrics it needs to monitor and with which thresholds. This not only saves you configuration time, but also provides you with in-depth insights into your IT infrastructure based on industry best standards.
Predictive monitoring
Benefit from sophisticated algorithms and adapt your IT infrastructure before new challenges occur: Checkmk provides advanced analytics based on historical data, which allows you to identify trends in your infrastructure or use resource utilization forecasts for capacity management.
