Vmware-Monitor for Xymon (VMX) is an extension for the Xymon systems- and network-monitoring system (formerly named Hobbit, the open-source successor of the big brother monitoring system) providing complete monitoring of a virtual environment based on VMware ESX without installing additional software on the monitored hosts.

Why using VMX?

Today virtual environments are running business critical services like ERP-, CRM- and databasesystems. Virtualization offers a great cost saving potential and lots of flexibility.

This flexibility however imposes new challenges for resource planning and issue fighting. New questions like the following are a result of this:

  • where is a particular virtual machine currently running?
  • where was a particular machine running in the past?
  • what is the overall load on the cluster?
  • what is the trend of resource consumption for a specific virtual machine, a epecific host or the whole cluster?

Vmware-Monitor for Xymon (VMX) helps with finding the answers to these questions and thus supports system administrators with running a VMware vSphere cluster as smooth as possible.

tracked metrics

This monitoring includes tracking of the CPU- and RAM-usage for each running virtual machine, an overview for each VMware-host and a one-click overview for all monitored VMware hosts. For each indiviual VM there is also a status page generated that provides additional information about hat VM (e.g. vmware-tools status, number of VMDKs and vCPUs).

track start and stop of VMs and vMotion events

Started and stopped VMs are also recognized as are moves of VMs between hosts (no matter if that move was initiated manually, by vMotion or an other mechanism).

hyperlinked status display

The results are displayed in five additional status-columns on your Xymon webinterface. These columns are hyperlinked so that it is very easy to navigate back and forth in the “dependency-tree” of your virtual environment.

trend graphs

Most collected metrics are graphed for trending purposes to provide a quick evolutionary overview and to aid capacity planning for your cluster.
