I recently wrote a blog post (which you can read here) about how XenApp and XenDesktop users can determine the HDX Display Mode by following advice in CTX200370 including methods using HDX Monitor and WMIC command line.
As it is possible to access this information from the command line via WMIC you can also to do this within a PowerShell Script calling WMIC.
I thought it might be useful to demonstrate the possibilities of using PowerShell via an example script.
Below is a script that can used or modified to average HDX or ICA metrics. The same metrics that are available and presented by HDX monitor. This might offer users the flexibility to use the raw metrics for in-depth analysis.
This script was written by one of our test developers Praveen Prakash for some internal testing of HDX. Which has got me thinking perhaps we should augment the HDX metrics to cover more metrics such as averaged data. Feedback welcome below in the comments box!
