How can I track if a web part is being used and where?

Question

In SP 2013 OnPrem, how can I track if a web part is being used or not?

And, if it is being used, how can I list all pages using those web parts?

We will migrate all structure and content to SharePoint Online using ShareGate. In Site Settings -> Web Parts I can see a list of 40 Web Parts and 9 of them are 3rd party Web Parts from a company called SPMeta2.

Before we go trying to find out how to migrate them, I would like to know if they are really being used and where. How can I track this info?

Thanks

One way you can do it, go to the one of the web parts page and at top page query string add ?contents=1 , then you will get 'web parts maintenance page' where you can see all web parts on that page,with the type, open or closed. If the web parts are closed, then those are not used.

The above manual process you can automate it using the PowerShell script, loop through all web part pages like above and check out the type whether open or closed.

I did a sample script to phrase DOM content from application page(yourpage?contents=1) which might help you for PowerShell automation.

$root = $url+'/_layouts/15/ManageCheckedOutFiles.aspx?List={'+$listID+'}'
Write-Host $root

$result = Invoke-WebRequest $root -Method Get -WebSession $webSession
//replace the logic to yours to phrase DOM, keep it as reference
$table = $result.ParsedHtml.IHTMLDocument3_getElementById("onetidTable")
$trs=$table.getElementsByTagName('tr')
for($i=1;$i -lt $trs.length;$i++){
    $tr =  $trs[$i];
    $check=$tr.GetElementsByClassName('ms-standardheader')
