Google Cloud Platform: how to monitor memory usage of VM instances : <p>I have recently performed a migration to Google Cloud Platform, and I really like it.</p>

<p>However I can't find a way to monitor the memory usage of the VM intances. As you can see on the attachment, the console provides utilization info about CPU, disk and network, but not about memory.</p>

<p>Without knowing how much memory is being used, how is it possible to understand if there is a need of extra memory?</p>
