Horizon View API

Reading Time: 1 minute

VMware recently added an Horizon View API as part of the PowerCLi 6.5 R1 release, which allows customers to interact with Horizon without the need for using the User Interface (UI). Amazing as this new Horizon API is, it’s not as easy as the usual PowerCLi CmdLets we are used to using and I’ve personally found information/settings difficult to find using the API. I’ve decided to share with my readers, some of the common API’s that will give you information that you might be looking for.

I’ve decided to share with my readers, some of the common API’s that will give you information that you might be looking for.

This isn’t a ‘Getting Started’ post. If you are new to the Horizon API, then I recommend reading the following two blog posts to help get you connected.

And for a full list of Horizon API’s, check out the official Horizon View 7.0.2 API documentation.

If there are any queries that you would like me to document, let me know and I’ll get them added. You can either leave a comment below or contact me directly.

Quick View

Sessions-v3
1. Sessions The Sessions screen displays the information of your Connected and Disconnected Horizon sessions.

NOTE: Horizon View API - Query Service is required to capture this data. You need to use the 'SessionLocalSummaryView' QueryEntityType.
Example:
C:\> $ViewAPI = $global:DefaultHVServers[0].ExtensionData

C:\> $query_service = New-Object "Vmware.Hv.QueryServiceService"

C:\> $query = New-Object "Vmware.Hv.QueryDefinition" 

C:\> $query.queryEntityType = 'SessionLocalSummaryView'

C:\> $Sessions = $query_service.QueryService_Query($ViewAPI,$query)

C:\> $Sessions.Results.NamesData | Select-Object -Property UserName,DesktopType,DesktopName,MachineOrRDSServerDNS



UserName                            DesktopType                         DesktopName                        MachineOrRDSServerDNS
