Measures reported by PVSStorePathTest

When configuring a store, administrators need to provide the default path to the store – this path represents the physical path to the vDisk. When a target device (desktop computer or server) boots, the Provisioning server checks the database for the Store name and the physical location where the vDisk assigned to that device resides, in order to provide it to the target device. If this path is unavailable or is slow, then the target device may not even boot. This is bound to leave users accessing those devices frustrated! To ensure that the user experience with PVS is top notch, administrators should identify unavailable and least responsive default store paths much before users complain of access delays. This is where the PVSStorePathTest test helps.

This test auto-discovers the default path configured for each store and proactively alerts administrators to the non-availability of a default store path or slowness in accessing the vDisk via the default store path. This way, the test pinpoints unavailable store paths and the ones that are slow.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Availability Indicates whether/not this default store path is available. Percent This measure reports the value 100 if the store path is available, and 0 if it is not.

Compare the value of this measure across store paths to identify those that are currently unavailable.

Breaks in network connection and absence of required access permissions are some of the common reasons for the non-availability of a store path.

For high availability of store paths, you may want to configure an override store path for each store. This way, it the default store path is unavailable for any reason, Provisioning services will automatically look up the override path to deliver vDisks to users.

Response_time Indicates the time taken to access the vDisk via this default store path. Secs A low value is desired for this measure. A consistent increase in this value is a cause for concern, as it indicates that responsiveness of the default store path is deteriorating. This could be owing to a flaky network connection. It could also be due to the concurrent usage of the store path by multiple target devices.
