VDI Storage Details Test

The storage server is used to store the virtual disks of the desktops. If the storage server is disabled or is experiencing a space crunch, the desktops using that server may be rendered unusable until such time the problem is resolved. Users attempting to access the desktops during the problem period would also be denied access owing to this. To make sure that the users' desktop experience does not suffer, you will have to periodically check the availability and usage of the storage servers used by desktops and promptly detect issues.

This test auto-discovers the storage servers of VMware vCenter, Microsoft Hyper-V, and Oracle VDI VirtualBox, runs periodic status and space checks on each server, and proactively alerts administrators to potential abnormalities in the space usage of the servers. The test also reports the number of desktops that are using a particular storage server so that, administrators can also analyze the impact of issues with that server.

This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Oracle VDI Broker as the desired Component type, set Performance as the Test type, choose the test from the disabled tests list, and click on the < button to move the test to the ENABLED TESTS list. Finally, click the Update button. 

Target of the test : An Oracle VDI Broker

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for each storage server used by the desktops on VMware vCenter, Hyper-V, and Oracle VDI VirtualBox.

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed
Host	The host for which the test is to be configured.
Port	The port number at which the specified Host listens to.
SudoPath	This test executes certain privileged VDA (Virtual Desktop Access) commands to pull out the desired metrics from the broker. To enable the test to run these commands, you first need to install a sudo package on the broker host. The procedure for installing this package is detailed in Pre-requisites for Monitoring the Oracle VDI Broker in an Agent-based Manner. Once the package is installed, you need to specify the full path to the install directory of the sudo package in the SudoPath text box.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Status	Indicates the current status of this server.		If the storage server is enabled, this measure reports the value Enabled. For a server that is disabled, this measure reports the value Disabled. The table below lists the numeric values that correspond to the states mentioned above: State Numeric Value Enabled 1 Disabled 0 Note: Typically, this measure will report the States indicated in the table above. However, in the graph of this measure, the status of the storage server will be represented using the numeric equivalents only - i.e., 1 and 0.
Total capacity	Indicates the total storage capacity of this storage server.	MB
Usage	Indicates the storage space in this server that is currently being utilized by the assigned desktops.	MB	Ideally, this value should be low.
Free capacity	Indicates the storage capacity in this server that is currently unused.	MB	Ideally, this value should be high.
Utilization	Indicates the percentage of the total capacity of this server that is being utilized.	Percent	A low value is desired. A high value or a gradual increase in the value indicates a potential space contention on the server.
Number of desktops	Indicates the number of desktops that are currently using this storage server.	Number	The value of this measure will help you understand how many desktops will be affected by a problem with a storage server.
