The time since user is inactive, is calculated as 'Idle' time and based on 'Idle Time Until Disconnect (VDI)', session gets disconnected after that.

I think the question was: after how many seconds of doing nothing is a session set as "idle"?

The default value is 900 secs (15min) before a session is marked as idle.

This can be changed using below reg. A value of -1 can be set to indicate that the session will never be considered idle.

Registry Hive HKEY_LOCAL_MACHINE

Registry Path Software\Policies\VMware, Inc.\VMware VDM\Agent\Configuration\XMLAPI

Value Name userIdleTimeout

Value Type REG_SZ

Default Value 900

Thanks for the info. Is it possible to see which sessions are idle? I don't think I can click on the graph

You can see which sessions are idle or for how long with PowerCLI - this sample returns that data:

CODE1458-Samples/Horizon 7 Samples/PowerCLI Sample at master · chrisdhalstead/CODE1458-Samples · Git...

OK. Would be great if we can drill down to the idle users in the console.

@chrisdhalstead Chris are those samples still available?
