SharePoint 2010 Custom Solution Site Usage Report

Question

We had old SharePoint 2010 site with few custom solutions deployed. There are about 1500 site collections. We would like to run PowerShell report to show if these custom solutions were used in any site collections at all. Is this possible? If yes, please provide PS code that we can use. Thanks Tee

Here is a sample script for your reference:

param (
    [Parameter(Mandatory=$false, HelpMessage='Solution Name')]
    [string]$SolutionName="",
    [Parameter(Mandatory=$false, HelpMessage='Solution Name')]
    [string]$WebApplicationUrl=""
)

$memoryAssignment = Start-SPAssignment;
$numberOfSolutionsFound = 0;
$webApplication = Get-SPWebApplication -Identity $WebApplicationUrl -ErrorAction SilentlyContinue -AssignmentCollection $memoryAssignment;

if($webApplication -ne $null) {

    #enumerate through site collections in web application
    $allSites = Get-SPSite -WebApplication $webApplication -Limit ALL -Confirm:$false -AssignmentCollection $memoryAssignment;
    foreach($checkSite in $allSites) {

        #Write-Output "Checking Site " $checkSite.Url " for solution " $SolutionName;
        if($SolutionName -eq "") {
            $checkSolutions = Get-SPUserSolution -Site $checkSite -AssignmentCollection $memoryAssignment;
            foreach($solution in $checkSolutions) {
                $output = New-Object -TypeName "System.Object";
                Add-Member -InputObject $output -MemberType NoteProperty -Name "Solution" -Value "";
                Add-Member -InputObject $output -MemberType NoteProperty -Name "SiteCollection" -Value "";
                $output.Solution = $solution;
                $output.SiteCollection = $checkSite;
                Write-Output -InputObject $output;
                $numberOfSolutionsFound++
            }
        }
        else {
            $checkSolution = Get-SPUserSolution -Identity $SolutionName -Site $checkSite -ErrorAction SilentlyContinue -AssignmentCollection $memoryAssignment;
            if($checkSolution -ne $null) {
                $output = New-Object -TypeName "System.Object";
                Add-Member -InputObject $output -MemberType NoteProperty -Name "Solution" -Value "";
                Add-Member -InputObject $output -MemberType NoteProperty -Name "SiteCollection" -Value "";
                $output.Solution = $checkSolution;
                $output.SiteCollection = $checkSite;
                Write-Output -InputObject $output;
                $numberOfSolutionsFound++
            }
        }
    }
}

Write-Output "Found $numberOfSolutionsFound Instances of Solution $SolutionName"
Stop-SPAssignment $memoryAssignment

You can save the script as a PS1 file and then execute the script using

PS C:\PS1FileLocation> .\Get-SPUserSolutionInWebApplication -WebApplicationUrl <WebAppURL>
