You can otherwise use the handy script below:
Generate a full memory dump
Inside of Kudu's online interface, goto
Debug Console -> Powershell via the menu at the top, then use the following script to generate a memory dump. The SysInternals tools are alreay installed on the machines by default.
$targetPID = (Get-Process | Sort-Object -Property "StartTime" | Select-Object -First 1).ID & "D:\devtools\sysinternals\procdump" -accepteula -ma $targetPID

Swap thread to... something
Honestly I have no idea what this is for. But go to
Debug -> Threads, then pick any thread that has text next to it.
Use the immediate window to show the static variable
Debug -> Immediate Window, then, in the new Immediate Window type the full name of the static variable you'd like to read.
