Fill multi dimension array with plain text in Powershell - powershell

Question

I am working on a Powershell script to monitor a SAN.
I successfully extracted a text file containing all the values from the system in Powershell with this code:
& "NaviSecCli.exe" -user xxxx -password xxxx -h host -f "C:\LUNstate.txt" lun -list
$Path = "C:\LUNstate.txt"
$Text = "Capacity \(GBs\)"
$Name = "^Name"
Get-Content $Path | Select-String -pattern $Text,$Name
This generates the following output:
Name: TEST-DATASTORE-1
User Capacity (GBs): 1536.000
Consumed Capacity (GBs): 955.112
Name: CV Snapshot Mountpoint
User Capacity (GBs): 1024.000
Consumed Capacity (GBs): 955.112
Now I can split the values through the colon, by putting the output into a variable:
$LUNArray = Get-Content $Path | Select-String -pattern $Text,$Name
$LUNArray | foreach {
$LUNArray = $_ -split ': '
Write-Host $LUNArray[0]
Write-Host $LUNArray[1]
}
The only interesting data is stored in $LUNArray[1], so I can just leave out Write-Host $LUNArray[0] which gives me the following output:
TEST-DATASTORE-1
1536.000
955.112
CV Snapshot Mountpoint
1024.000
955.112
Now the tricky part, I would like to put the data into a multi dimensional array. So I would get the following array layout:
LUN Usercap ConsCap
TEST-DATASTORE-1 1536.000 955.112
CV Snapshot Mountpoint 1024.000 955.112
The input file looks like this:

Answer 1

$filePath = 'absolute path'
$content = [IO.File]::ReadAllText($filePath)
[regex]::Matches(
$content,
'(?x)
Name: [ ]* ([^\n]+) # name
\n User [ ] (Capacity) [^:]+: [ ]* ([^\n]+) # capacity
\n Consumed [ ] \2 [^:]+:[ ]* ([^\n]+)' # Consumed
) |
ForEach-Object {
$LUN = $_.groups[1].value
$Usercap = $_.groups[3].value
$ConsCap = $_.groups[4].value
# process $Lun, $Usercap and $ConsCap
}

Answer 2

Build a list of custom objects, like this:
& "NaviSecCli.exe" -user xxxx -password xxxx -h host -f "C:\LUNstate.txt" lun -list
$datafile = 'C:\LUNstate.txt'
$pattern = 'Name:\s+(.*)[\s\S]+(User Capacity).*?:\s+(.*)\s+(Consumed Capacity).*?:\s+(.*)'
$LUNArray = (Get-Content $datafile | Out-String) -split '\r\n(\r\n)+' |
Select-String $pattern -AllMatches |
Select-Object -Expand Matches |
% {
New-Object -Type PSObject -Property #{
'LUN' = $_.Groups[1].Value
$_.Groups[2].Value = $_.Groups[3].Value
$_.Groups[4].Value = $_.Groups[5].Value
}
}
The data can be displayed for instance like this:
"{0}: {1}" -f $LUNArray[1].LUN, $LUNArray[1].'Consumed Capacity'
