Linux server monitoring

Get broad visbility into your Linux servers' health and performance – no matter which distribution you use. We support the monitoring of Red Hat Enterprise Linux, Fedora, CentOS, openSUSE, SLES and other derivatives, as well as Debian, Ubuntu, and all other DEB-based distributions. Our native agent monitors all important services and hardware, providing you with the information you really need. Augment the agent with a wide set of off-the-shelf plug-ins to monitor applications running on your servers.

Benefits of our Linux server monitoring:

  • minimalistic footprint, since the agent requires little CPU, RAM and hard drive space
  • full transparency, because only a shell script is executed in which you can see all commands
  • complete security, since the agent permits no access from the network whatsoever

Windows server monitoring

Monitor your Windows servers and get insights into Windows services and processes, network interfaces, filesystems, CPU and memory usage. Benefit from an integrated log monitoring and monitoring of key applications for Windows servers like Exchange, Active Directory, MSSQL and Skype.
Check_MK even supports the monitoring of almost ancient systems like Windows XP and Windows Server 2003, and of course the latest Windows OS as well.
And this all with a simple executable file without dependencies on DLLs while providing security — no malicious code can be injected as the Windows agent doesn't read data from the network.

Virtual server monitoring

Monitor resource utilization across datacenters, clusters, ESX/ESXi hosts and virtual machines. Check_MK supports the monitoring of all major virtualization platforms like VMWare ESXi, Microsoft Hyper-V and associated virtual machines in real-time.
Virtual server monitoring is already integrated in Check_MK, so that your virtual machines can be monitored with almost no additional set-up.

Check_MK itself can also be run on a virtual server infrastructure with the virtual appliance.
