    <p>I'd simplify this significantly by using capture groups in your regex and also using the switch condition's ability to process regular expressions. </p> <p>Oh and I'd use a dictionary to ensure that each server is tracked individually while allowing you to access the data after the capture is complete. This would also give you the ability to do some historical tracking and comparison if you saved the data... but that's outside of this scope ;)</p> <p>e.g.</p> <pre><code> $addressesInUse = @{}; $addressesFree = @{}; foreach ($server in $serverList) { $mibinfo = netsh dhcp server \\$server show mibinfo; #| where-object {$_-match "No. of Addresses in use = "} | foreach ($info in $mibinfo) { switch -regex ($info) { "No. of Addresses in use = (?&lt;count&gt;\d+)" { $val = $Matches["count"]; if ($addressesInUse.ContainsKey($server)) { $addressesInUse.Add($server,$val); } else { $scopeCount.$server += $val; } break; } "No. of free Addresses = (?&lt;count&gt;\d+)" { $val = [int]::Parse($Matches["count"]); if ($addressesFree.ContainsKey($server)) { $addressesFree.Add($server,$val); } else { $addressesFree.$server += $val; } break } } } } foreach ($key in $addressesFree.keys) { $total = $addressesInUse.$key + $addressesFree.$key; $percent = [Math]::Round($addressesInUse.$server / $total*100,2) Write-Host ("DHCP availablility for server {0}" -f $key); Write-Host ("No. of Addresses in use = {0}" -f $addressesInUse.$key); Write-Host ("No. of free Addresses = {0}" -f $addressesFree.$key); Write-Host ("Total Addresses: {0}" -f $total); Write-Host ("Percent in use: {0}%" - $percent); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
