One Checkmk instance can monitor thousands of servers and can easily scale horizontally with our distributed monitoring setup.

Intelligent Monitoring

Checkmk intelligently discovers which metrics to monitor on your server without needing any additional configuration.

It's fast to get started

Checkmk enables you to go from zero to monitoring in less than 15 minutes. Thus, the installation of your new server monitoring solution is super easy and fast!

An all-in-one server monitoring software

Your organization uses multiple types of servers. It is therefore important to use a server monitoring software that can help you can get started with all of your server monitoring at once.

Checkmk provides this flexibility through its large collection of more than 2,000 plug-ins. Here are some examples of server types which can be monitored with Checkmk:

Linux server monitoring

Get an accurate overview of your Linux servers' health and performance. We support the following Linux OS: Debian, Ubuntu, Red Hat Enterprise Linux, Fedora, CentOS, openSUSE, SLES and other derivatives, as well as all other DEB-based distributions.

Windows server monitoring

Monitor your Windows servers and gain insights into critical metrics such as CPU, memory, disk usage, services, processes, network interfaces, filesystems and more. Quickly identify and resolve any performance or availability issues.

Benefits of Windows server monitoring with Checkmk:

Virtual server monitoring

Monitor the health and availability of your virtualized server environment. Checkmk supports the real-time monitoring of all major virtualization platforms, such as VMware ESXi, Microsoft Hyper-V and associated virtual machines.

Virtual server monitoring is already integrated in Checkmk, so that your virtual machines can be monitored with almost no additional set-up. Checkmk itself can also be run on a virtual server infrastructure within the virtual appliance.

Centralized Asset Management

The Checkmk hardware & software inventory is built to automatically discover and manage your hardware & software asset information on all servers and workstations being monitored.

Easily identify hosts with vulnerable and outdated software versions, so that you can act to secure your IT. Checkmk also stores the history of the inventory of a server and helps you track changes in your environment, e.g. a BIOS update, RAM upgrade.

Integrate Checkmk with your Configuration Management Database (CMDB) to always have an up-to-date overview of your IT.

Visualize data for best server monitoring

As one of the best server monitoring software Checkmk not only provides powerful monitoring agents for most server operating systems, such as Windows, Linux and Unix. It also supports agentless monitoring via SNMP, IPMI, WMI or Redfish as well as data collection via server vendor interfaces.

Checkmk combines status, metrics, and log-based data in one solution and provides numerous visualization options with powerful dashboards. This allows you to get the most out of your monitoring.

Monitor server performance

Checkmk allows you to just focus on the performance metrics of your systems, if necessary. By monitoring server performance, you can strictly keep an eye on CPU utilization, memory consumption, disk I/O and network performance of your physical servers or more specific metrics regarding the use case of the server.

Thus, you monitor for example the response time of a web server, the network bandwidth utilization for a backup server, or even the waiting time for each written memory block (latency) and input/output operations per second (IOPS) of a file server.

A server performance monitoring tool like Checkmk can provide clues to possible bottlenecks and help in eliminating performance problems as well as using the performance data to verify SLAs, such as whether servers provided the required performance in a specific time frame.

The whole Checkmk environment has a very mature, stable foundation of supported checks and performance counters. Yet it grows almost on a daily basis.

Support for new systems is being implemented very often and if you are willing to request it yourself, you can have it included in the core distribution in very little time. This agility really has no match among the larger competitors.
