VM Resource and Availability Service - New VMware Fling

This Fling enables you to perform a what-if analysis for host failures on your infrastructure. You can simulate failure of one or more hosts from a cluster (in vSphere) and identify how many:
  • VMs would be safely restarted on different hosts
  • VMs would fail to be restarted on different hosts
  • VMs would experience performance degradation after restarted on a different host
With this information, you can better plan the placement and configuration of your infrastructure to reduce downtime of your VMs/Services in case of host failures.


  1. Open to access the web service.
  2. Click on "Simulate Now" to accept the EULA terms, upload the DRM dump file and start the simulation process.
  3. Click on the help icon (at the top right corner) for a detailed description on how to use this service. To download the instructions PDF click here
  4. Upload the DRS dump File here 

    DRMdiagnose reviews the DRS cluster snapshot. This snapshot contains the current cluster state and the resource demand of the virtual machines. The cluster snapshot is stored on the vCenter server. These snapshot files can be found:

  1. vCenter server appliance: /var/log/vmware/vpx/drmdump/clusterX/ 
  2. vCenter server Windows 2003: %ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter\Logs\drmdump\clusterX\
  3. vCenter server Windows 2008: %ALLUSERSPROFILE%\VMware\VMware VirtualCenter\Logs\drmdump\clusterX\ 
You can use WinSCP to download this file from vCenter Appliance to Windows Machine. Download the latest timestamp file
