Using the Memory Machine Dashboard
You can view system resources and performance metrics, and create and restore snapshots in MemVerge Memory Machine using the Memory Machine Dashboard, a web UI application running on one of the installed hosts.
Getting Familiar with the Memory Machine Dashboard
Memory Machine Dashboard is a web-based user interface (UI) from which an administrator can view memory and processor statistics and capture and restore application snapshots on any number of servers under management by a Memory Machine instance.
The Memory Machine Dashboard Console Screens
The Memory Machine Dashboard has several console screens: a Global Dashboard, a Host Overview Console, an Applications Console, an Alerts Console, a Jobs Console, a Usage Report Console, and a Settings Console.
The Host Overview Console
The Host Overview Console shows the amount of memory on the host, memory used over time, and use of memory by application instances.

Overview and Installation
