Use the Horizon VDI Pools dashboard to view the performance of VDI desktop pools and sessions in your Horizon environment. A VDI desktop pool can be a linked-clone or instant clone desktop pool, automated desktop pool, or manual desktop pool.
The widgets below the VDI Desktop Pools and VDI Desktop Pool Indicator Metrics widgets are organized into two columns: the left column contains widgets for VDI desktop pool virtual machines and the right column contains widgets for VDI desktop pool sessions. Each column contains a Heat Map widget and four Top-N Analysis widgets.
The VDI Desktop Pools widget is the master widget for the Heat Map widgets on the dashboard. For example, when you select a desktop pool in the VDI Desktop Pools widget, the VDI Desktop Pool VMs widget shows the desktop virtual machines in that desktop pool and the VDI Desktop Pool Sessions widget shows the desktop sessions that are currently logged on for that desktop pool.
You can click the Dashboard Navigation button on a widget toolbar to navigate to other dashboards. In some widgets, including VDI Desktop Pools and VDI Desktop Pool VMs, you can use Dashboard Navigation button to launch Horizon Administrator.
Configuring Applications for Viewing in Reports
In order to use the following reports from the VDI Pools Dashboard, you must first configure applications that you want to monitor:
Horizon Desktop Application Usage
Horizon Desktop Application Instance Usage
Use the following steps to configure applications for these reports:
Edit /usr/lib/vmware-vcops/user/plugins/inbound/V4V_adapter3/conf/v4v-desktop-app-config.properties in the master node. Add application information to it. For example, to add information for calculator and notepad applications, modify the file like so:
#app name, app full path, pod name(optional) #for pod Cluster-SERVER621 calculator,C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Calculator.lnk,Cluster-SERVER621 #for all pods notepad,C:\Windows\notepad.exe
By default, the app instance feature is disabled, and you can only see Desktop Applications Tier and Desktop Application objects. To enable the app instance feature, go to /usr/lib/vmware-vcops/user/plugins/inbound/V4V_adapter3/conf/v4v.properties and change the value of enableDesktopApplicationInstance to true.
Restart the entire cluster after making these changes, or just restart the remote collector. Use service vmware-vcops -full-restart on the remote collector. The property has to be changed on the master node; the remote cluster is updated after the restart.
Tips for Using the Horizon VDI Pools Dashboard
Use the graphs in the VDI Desktop Pool Indicator Metrics widget to see the values of selected metrics over time and obtain a quick view of the trends in KPIs.
The colored rectangles in the VDI Desktop Pool VMs and VDI Desktop Pool Sessions widgets represent particular objects. For example, in the VDI Desktop Pool VMs widget, each rectangle represents a particular virtual machine. You can point to a rectangle to view basic information about its associated object.
The size of the rectangle indicates the value of one metric, the color of the rectangle indicates the value of another metric, and the widget configuration determines which metric values that the widget shows. For example, if you select Sized by Workload - Colored by Health from the Configuration drop-down menu, rectangles are sized according to the value of the workload metric and are colored according to the value of the health metric. Red indicates a low value and green indicates the high end of the value range.
Use the Top-N Analysis widgets for desktop virtual machines to view the virtual machines that have the highest CPU, memory, disk, and network workload. Use the Top-N Analysis widgets for desktop sessions to view the sessions that have the highest latency, transmission bandwidth, transmission packet loss, and logon times. Viewing the extreme performers in any category can help you to assess the overall performance of your environment.
Use the Desktop Applications widget to view a list of all the configured applications hosted by a VDI desktop.
Use the Desktop Application Users widget to see a history of user logon information for a selected application, indicating who uses the application, and when the application is used.
