VDI Core Service Status Test

The central component of Oracle Virtual Desktop Infrastructure is the Oracle VDI Core. The Oracle VDI Core provides all the functionality needed to build and manage large scale virtual machine deployments. In addition to its management capabilities, the Oracle VDI Core is also responsible for the brokering of virtual desktops on behalf of desktop access clients.

The Oracle VDI Core component is driven by the VDI Core Service that runs as a module within the Common Agent Container (Cacao). If you encounter any issues while working with the Oracle VDI broker, you should first check the status of Cacao as well as the status of the Oracle VDI Core service module.

This test monitors the VDI Core Service and reports its current status.

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 the Oracle VDI broker being monitored.

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

Operational state

Indicates the current operational state of the Oracle VDI core service.

 

This measure reports the value Enabled or Disabled depending upon the current state of the VDI core service.

The table below lists the State values reported by this measure and the numeric values that correspond to each of the states:

State Numeric Value
Enabled 100
Disabled 0

Note:

Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the operational state of the VDI core service will be represented using the numeric equivalents only - i.e., 0 and 100.

Administrative state

Indicates the current administrative state of the VDI core service.

 

 

This measure reports the value Locked or Unlocked depending upon the current administrative state of the VDI core service.

The table below lists the State values reported by this measure and the numeric values that correspond to each of the states:

State Numeric Value
Unlocked 100
Locked 0

Note:

Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the administrative state of the VDI core service will be represented using the numeric equivalents only - i.e., 0 and 100.

Availability

Indicates the current availability status of the Oracle VDI core service.

 

If the VDI core service is not currently operational - i.e., if the Operational state measure of this test reports the value Disabled - then the Availability measure will not report any values; in such a case therefore, this measure will not appear in the eG monitoring console.

On the other hand, if the Operational state of the VDI core service is Enabled, then this test will report one of the following values for the Availability measure:

  • Dependency
  • Off_line
  • Failed

The numeric values that correspond to each of the Availability states listed above are discussed in the table below:

State Numeric Value
Dependency 1
Off_line 2
Failed 3

Note:

Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the availability state of the VDI core service will be represented using the numeric equivalents only - i.e., 1 to 3 only.

Module health

Indicates the current health of the VDI core service module.

 

The value of this measure will either be Good health or Bad health, depending upon how healthy the VDI core service module currently is.

The table below lists the State values reported by this measure and the numeric values that correspond to each of the states:

State Numeric Value
Good health 100
Bad health 0

Note:

Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the module health will be represented using the numeric equivalents only - i.e., 0 and 100.
