Virtual server monitoring

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

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 with the virtual appliance.

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

Easily identify hosts with vulnerable and outdated software versions and act and secure your IT.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 view on your IT.

Server monitoring software and hardware inventory

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.
Wolfgang G. - Service Manager

Checkmk is a phenomenal monitoring program that is constantly improving while remaining flexible enough for customizing to perfectly fit your unique monitoring needs.

With the ability to write your own custom plugins in Python there is truly nothing that can't be monitored according to your specification. The fact that it can do all this on a single core, 4GB of RAM Virtual Machine is mind-blowing.
