Measures reported by QVDOSFTest

An Operating System Flavour (OSF) is loaded into any number of virtual machines on a QVD Server Node in order to serve a virual desktop to a client. The OSF is usually installed into QVD along with particular runtime parameters such as the amount of system memory that should be available to it.

This test auto-discovers the Operating System Flavours configured on the QVD and reports the total memory size of each OSF. In addition, this test indicates if overlay is enabled on each OSF.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
ram Indicates the total memory size of this Operating System Flavour. MB  
Overlay Indicates whether/not overlay is enabled on this Operating System Flavour.   Virtual Machines make use of overlays in order to best utilize different elements of the Guest operating system, and in order to make particular elements persistent. For instance, while write activity is not persistent within the actual OSF that is loaded, it is important that data written to the user's home folder or desktop is stored for future connections to the virtual desktop. Overlays can also be used to make other data such as log and tmp files persistent from a user perspective.

This measure reports a value Yes if the overlay is enabled and a value No if otherwise.

The numeric values that correspond to the measure values discussed above are listed in the table below:

Numeric Value Measure Value
1 Yes
0 No

Note:

By default, this measure reports the values Yes or No only to indicate whether the overlay is enabled or not. The graph of this measure however, is represented using the numeric equivalents - 0 or 1.
