Check whether a RunspacePool is already open on a machine

Question

I have a process that runs Powersell script on a VM. This script defines a RunspacePool on the VM and sets threshold (no. of Runspaces) based on the resource capability of that VM. This process is recurring so I do not want it to keep defining and opening RunspacePools when there is already one defined and opened on that VM

At the beginning of the Powershell script, I have tried to check whether a Runspacepool is already defined\ opened by calling RunspacePoolStateInfo or RunspacePoolAvailability properties. But these are not identified as the Runspacepool object itself is not available in the new window that the process opens up to run the script

I am basically looking for a way to identify that a RunspacePool is open on a VM by using Powershell scripting

Answer for PowerShell V5 and newer

You can get the Runspacess in the current processes by running

Get-Runspace

or if you know the name

Get-Runspace -Name <name>

Remote Runspaces in PowerShell V5

If the Runspace you want to check is in another process, you must first do this.

Enter-PSHostProcess -Id <int>

or

Enter-PSHostProcess -Process <ProcessObject>
