Measures reported by VcConnTest

VDM works closely with VMware VirtualCenter to provide advanced virtual desktop management capabilities, such as virtual desktop creation as part of pool management, and power operations such as automatic suspend and resume, which reduce the memory and processing power required to host virtual desktops. By leveraging the capabilities of VMware Virtual Infrastructure 3, desktops can run even when server hardware fails and recover quickly from unplanned outages without duplicate hardware. Multiple VirtualCenter servers are supported, and VDM can scale horizontally to support many virtual desktops. The non-availability of one/more VirtualCenter servers can therefore affect the core functionality of VDM. Using this test, administrators can be proactively alerted to the following:

• the non-availability of the VirtualCenter server
• the inability of the VDM to establish a TCP connection with the VirtualCenter server
 The measures made by this test are as follows:

Measurement	Description	Measurement Unit	Interpretation
Availability	Indicates whether the VirtualCenter is available or not.	percent	The value 100 indicates that the VirtualCenter is available, and the value 0 indicates that the VirtualCenter is not available. Non-availability of the VirtualCenter would render the VDM unable to perform dynamic desktop creation and control operations such as suspend and resume on virtual desktops.
Response_time	Indicates the time taken by the VirtualCenter to respond to requests it receives.	Secs	Ideally, this value should be low. A very high value could indicate a poor network connection between the VDM and the VirtualCenter
Tcp_connection_availability	Indicates whether/not the VDM is able to establish a TCP connection with the VirtualCenter server.	percent	The value 100 indicates that the VDM successfully connected to the VirtualCenter, and the value 0 indicates that the TCP connection attempt failed.
