Measures reported by AppVolStorageTest

Shared storage has separate datastores for desktop and RDSH server master images and for App Volumes AppStacks. Shared storage is specific for all ESXi hosts that host desktops connecting to AppStacks and writable volume. If local storage is used, AppStacks can be placed on the same datastore where VMs reside. The App Volumes service can be configured to refer to local storage before referring to shared storage. If specified AppStacks exist on the local storage, then these AppStacks are mounted in favor of duplicate copies that exist on shared storage.

The VMware App Volumes Manager relies heavily on the storage (datastores) for connecting to the AppStacks and Writable volumes that hosts the applications and other files. Unavailability of a datastore or the lack of storage space in a datastore can severely hamper the operations of the virtual desktop and can consequently delay the boot time of the virtual desktops as the applications will not be attached to the desktop. By keeping constant tabs on the space usage of each datastore managed by the target VMware App Volumes Manager, this test proactively alerts you to potential space contentions on a datastore.

Outputs of the test :One set of results for each datastore on the target VMware App Volumes Manager being monitored.

Descriptor:Datastore

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
No_of_appstack Indicates the number of AppStacks placed on this datastore. Number  
No_of_writables Indicates the number of writable volumes placed on this datastore.. Number  
Total_storage Indicates the amount of space allocated to this datastore. TB Ideally, the value of this measure should be low. If this value grows close to that of the Total storage space measure, then you may consider adding more storage to the datastore, or free up the space in the datastore by deleting unnecessary data.
Used_storage Indicates the amount of space that is already utilized by this datastore. TB

Comparing the value of this measure across datastores will help you identify the datastore that is utilizing the maximum amount of storage space.

A high value is desired for this measure.
Free_storage Indicates the amount of space that is available for use in this datastore. TB A sharp/consistent decrease in the value of this measure is an indication for the administrators to add more free space to the datastore before the datastore runs out of free space.
Storage_usage Indicates the percentage of space utilized by this datastore. Percent A value close to 100% indicates that datastore is currently running out of space.
