I have a few VMs set up as ADO (VSTS) build servers and thought I'd look into CPU and RAM usage over time to optimize the VM size.
However I have had a hard time finding anything in Azure that allows me to investigate memory usage in VMs.
The VMs do have the IaaS WAD extension installed and I can view things like CPU usage in Monitor but there doesn't seem to be any Monitor metric related to memory. Do I really need to move to a third party like Datadog to get such basic information presented in a graph?

They have removed the "host metric" memory from VM's. You have to use the new Insight option to expose the memory usage.

Go to your VM -> Monitoring -> Insight and onboard it to Insight if needed. After it is onboarded and has started collecting data(20-30 min) you can choose the performance tab:
