According to https://azureossd.github.io/2015/09/18/taking-a-crash-dump-of-nodejava-process-using-the-procdump-on-azure-webapp/
we could collect the memory dump of node.exe with ProcDump, where we can use WinDBG to open it.
Are there any tools or maybe WinDBG extensions including its commands that could help us investigate high memory?
