PVS Device Activity Test
Citrix Provisioning Services deliver patches, updates, and other configuration information to target devices i.e. virtual machines/desktops, at boot time through vDisks over the network. The target devices boot from the network, connect to the target PVS server and stream down the associated vDisks after the boot process. If the boot process of the target devices takes longer time to complete or fails, vDisks containing required information will not be streamed to the devices. As a result, the devices will bot be booted or updated with latest information. This, in turn, will seriously affect the user experience with the target devices and even delay/stop business-critical service deliveries performed from the devices. To avoid this, it is imperative to continuously track how quickly the devices are booted so that you will be forewarned of probable delays and failures. The PVS Device Activity test can help you in this regard!
The test monitors the target PVS server and promptly captures the average and maximum time taken by the target devices to complete the boot process. In addition, this test also reveals the count of devices that are booted successfully and the number of devices that are slow at boot process. These metrics will ease troubleshooting when validating PVS functionality as well as when tracking down potential issues in the boot process.
Target of the test : Citrix Provisioning server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for the Provisioning server being monitored.
Parameter | Description |
---|---|
Test Period |
How often should the test be executed. |
Host |
The IP address of the host for which the test is being configured. |
Port |
Refers to the port used by the Citrix Provisioning server. By default, this is 54321. |
Max Acceptable Boot Time in Seconds |
Specify the maximum duration (in seconds) for which a boot process should have completed for it to be accepted as successful. The default value is 60. |
DD Frequency |
Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency. |
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Average boot time of devices |
Indicates the average time taken by the devices to complete boot process. |
Seconds |
The detailed diagnosis of this measure reveals the device name, the time at which the boot process was started and the time duration of the boot process in seconds. |
Devices moved for IO |
Indicates the number of devices for which the streaming process has been directed to the PVS server thorugh IO port. |
Number |
Using this measure, administrators can easily find out how many devices established connections to the target PVS server successfully. The detailed diagnosis of this measure the time at which the devices were moved to IO port, the device name and IP address and port of the target PVS server. |
Devices slow at boot up |
Indicates the number of devices that are slow during boot process. |
Number |
The detailed diagnosis of this measure reveals the device name, the time at which the boot process was started and the time duration of the boot process in seconds. |
Devices booted |
Indicates the number of devices that are booted sucessfully. |
Number |
The detailed diagnosis of this measure reveals the device name, the time at which the boot process was started and the time duration of the boot process in seconds. |
Devices in "Login Initiated" state |
Indicates the number of devices that requested vDisk from the target PVS server. |
Number |
The detailed diagnosis of this measure reveals the device name, and the time at which the boot process was started. |
Devices in "Service granted" state |
Indicates the number of devices that are successfully streaming the assigned vDisk. |
Number |
A high value is preferred for this measure. The detailed diagnosis of this measure reveals the device name, the time at which the boot process was started, IP address and port. |
Maximum boot time across devices |
Indicates the maximum time taken by the devices to complete the boot process. |
Seconds |
The value of this measure should be low. The detailed diagnosis of this measure reveals the device name, the time at which the boot process was started and the time duration of the boot process in seconds. |
Powered down devices |
Indicates the number of devices that are powered off. |
Number |
The detailed diagnosis of this measure reveals the device name, and the time at which the boot process was started. |
