Hello, I am working on adapting a script provided to me by a friend to handle multiple functions, problem is, his network is only 700 or so computers, so he is using Jobs. My network has roughly 6000 computers, so jobs is crashing my workstation, or taking too long to accomplish. I've moved to Runspace, Tome's ForEach-Parralel function. Issue I'm running into is that the script is built to capture results into an array, where it will use that data for multiple functions.

UPDATE:

I've found the answer here;
Sharing Variables and Live Objects Between PowerShell Runspaces

Only thing I'm stuck on now is sorting through the returned data, instead of an out grid view with multiple columns to sort and utilize I get a has table that looks like this;

I would like to be able to get the data into columns so I can use them for various troubleshooting, online machines will get checked for remote capabilities, repair ones that don't have remote capabilites, connect and check IAVM status, etc... Once I get this figured out I'll be adopting it a larger script for all of these functions, some which pull 10+ variables to display as columns. I could export as CSV, import into Excel, Delimit and process the data manually, but I have to hope powershell has a way of streamlinning this.

Seems like it may have what I need as well, can anyone prvide insight as to the key procedures being done that allow the capture and retrieval?
