That is unfortunate, the vSphere team won't at least provide an exported PNG graph of the cluster or virtual machine. The one item you can do is leverage perfmon for recording basic resource metrics on the VM.
It is also unfortunate the slightly older 2103 client did not help. The issue impacted both PCOIP and Blast in my recent experience.
On the timeout feature, I'm not familiar but as an alternate test you should be able to try a non-teradici device if allowed on a company workstation/laptop with the Horizon Client/HTML Access.
One last item, there are valuable logs located both on the connection server and VDI desktop. They are specified in this link and are great for correlating timestamps in the client logs.

One final item, I'm investigating additional symptoms around this issue occurring in the last 24 hours. It may be the same issue or a new variation, I'll post back here.
