Data domain data pull using PowerShell to SSH

Question

I'm currently working on a Powershell script that will run on a server and ssh to a text list of data domains on a weekly/monthly basis. From this list, it will loop through each, connecting and running a command to grab information from each DD. I have no experience with Powershell prior, and my knowledge is limited to university-education levels of Linux and standard commands.

The script was based off the following:

I'm currently trying to modify the script to meet my needs but have been stuck on the output. Currently I can ssh into each data domain and pull out data with "df" and post-comp but to grab other data is still a mystery to me.(There aren't alot of sources even on the EMC site).

To summarize, I am wondering if anyone has any idea how to grab more information from the following commands:

system - show all/ show modelno/ show hardware/ show stats
filesys - show space

Here is a basic overview of my script so far: ( I apologize for the mess, I could only do so much editing)

          WriteLog "Checking Data Domain Available Space"
          $includeList="Cleanable GiB|--------|/data: post-comp" #Data domain format command to print
          $DB = Get-Content $answerfile #inputstream from file


          foreach ($Data in $DB){ ##bracket required on same line for foreach / foreach for iteration through data domains
              $hostname = $Data.Trim() #gets host name without new line character for the SSH command.

                #~~~~~~~~~ Password Set up ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                if($hostname -eq "139.12.34.56" -Or $hostname -eq 
 "10.123.11.108") ##if hostname is one of the selected, change password
 to correct 
                {
                $passwd = "12345PASS"
                }
                else #all other servers require this secondary password
                {
                $passwd = "54321PASS" 
                }
                #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                # Options: Hardcoded(current) / Read write from file.
                # With more passwords: Hardcoded = Switch
                #                      ReadWrite = Add to list


                #~~~~~~~~~~  SSH command and exe command Set up Process~~~~~~~~~~~~~~~~~
                $exe = "CMD" #Launch CMD for use


              $command = "/C $plinkcommand $user@$Data -pw ""$passwd"" df" #ssh command
              $Data > 
                #$command2 = "/C $plinkcommand $user@$Data -pw ""$passwd"" System show preformance" #ETC
                #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                # Currently supporting structure(below) to run other commands
                # Commands to be added: System  - (show all, show modelno, show compression, show hardware, show stats)    
                #                       Filesys - Show space
                #                       Possibly more to be added at a later time


                #~~~~~~~~~~~~~ Navigation of directories in host computer ~~~~~~~~~~~~~~
                invoke-expression "cd /" #Change directory to Root          
                invoke-expression "cd /users/kevindong/documents/powershellscripts" #change directory to
                plink location
                #Set up command to navigate to plink (requires set up dependedant on computer)
                #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                # Possible update to "invoke-expression", and possible specific targeted location of operating file directory

                #~~~~~~~~~~~~~ Execution of SSH data grab commands ~~~~~~~~~~~~~~~~~~~~~

              $outputcontents = &$exe $command ##ssh connect execution + "df" command

              if ($outputcontents -ne "") #if SSH is not null
              {

                  $outputcontents | ForEach-Object { #foreach requires bracket on same line
                       if ($_ -match $includeList) { WriteLog $_ }  #run data collection

                    #add commands here and write log them    
                    }
              }
                #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

          }

Thank you to anyone who took/takes a look into my problem. I appreciate it.
