In order to diagnose WP issue sometimes we need to collect memory dump (https://support.tibco.com/s/article/Tibco-KnowledgeArticle-Article-45793),
however it's kinda difficult to know the instance's process id especially when there are many instances in 1 server(commonly if server is equipped with lots of memory), currently I use this powershell command to do so.
Get-CimInstance Win32_Process | Where-Object {($_.Name -eq 'Spotfire.Dxp.Worker.Host.exe') -and ($_.CommandLine -like '*b2d621c6-d3fe-48f3-b28d-55ca8b2c0065*')}| select processId
Please show process id for each WP/AS instance in Monitoring&Diagnostics page.
