Using the Memory Machine Management Center
Memory Machine Management Center (M3C) is a web UI application available on the host that is running the Memory Machine Management Service. You can view system resources and performance metrics; create and restore snapshots; schedule jobs; and more in M3C.
Using Snapshots in Memory Machine Management Center
Use ZeroIO Snapshot from Memory Machine Management Center to capture the state of a running process. You can then stop the process and restore it to the running state captured in the snapshot.
Using Snapshots in Memory Machine
Capturing a snapshot is almost instantaneous, requiring only that a small amount of metadata be saved to a storage device.
Restoring a Snapshot
Choose Restore in the Snapshot Information Dialog to restore a snapshot.

Overview and Installation
Getting started with MemVerge Memory Machine requires that you understand some background information about how persistent memory works. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.
Using the Memory Machine Management Center
Memory Machine Management Center (M3C) is a web UI application available on the host that is running the Memory Machine Management Service. You can view system resources and performance metrics; create and restore snapshots; schedule jobs; and more in M3C.
- Getting Familiar with the Memory Machine Management Center
  Memory Machine Management Center (M3C) 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 Memory Machine.
- Managing Hosts
  Use the Hosts Console to manage hosts and to view statistics about application instances, memory performance, and snapshots on individual hosts and host groups.
- Managing Applications
  You can view application instances from the Applications Console. Application instances must be started and stopped using the command line.
- Using Snapshots in Memory Machine Management Center
  Use ZeroIO Snapshot from Memory Machine Management Center to capture the state of a running process. You can then stop the process and restore it to the running state captured in the snapshot.
  - Using Snapshots in Memory Machine
    Capturing a snapshot is almost instantaneous, requiring only that a small amount of metadata be saved to a storage device.
    - Capturing a Snapshot Using Memory Machine Management Center
      Use Capture Snapshot in the Instance Memory Usage Display to capture a snapshot of the selected instance.
    - Scheduling Snapshots
      Schedule snapshots, either one-time or recurring, from the Applications Console.
    - Deleting a Snapshot
      Choose Delete in the Snapshot Information Dialog to delete a snapshot.
    - Restoring a Snapshot
      Choose Restore in the Snapshot Information Dialog to restore a snapshot.
      - Restoring a TTY Session
        If a restored application instance has a TTY session, Memory Machine Management Center (M3C) opens the session using the tmux utility.
  - Cloning a Snapshot with Memory Machine Management Center
    To clone a snapshot of an application, use the All Actions Dropdown in the Applications Console.
  - Exporting and Importing Snapshots
    You can export snapshots from Memory Machine to an unmanaged file system, then later restore the snapshot to the same or a different host.
  - Replicating a Snapshot
    Click a snapshot in the Applications Console to replicate a snapshot to a different host.
  - Viewing Snapshots
    View snapshots graphically, in a tree structure, or as a sortable list in the Snapshot Display Panel.
- Viewing Metrics and System Status
  The Memory Machine Management Center makes it easy to view and compare running processes, snapshots, system resources and performance metrics.
Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.
Working with Applications
MemVerge provides additional instructions for some popular applications supported by Memory Machine, either to assist with complex setup or to support additional functionality.

Restoring a Snapshot

Choose Restore in the Snapshot Information Dialog to restore a snapshot.

About this task

Warning: If a snapshot fails to restore properly, the cause could be a dependency upgrade. See Cannot Restore Snapshots.

Procedure

Choose a snapshot in the Snapshot Display Panel. See Viewing Snapshots.
Optional: If the application instance has an associated TTY session, M3C tries to reconstitute the session using tmux. You can assign a name to this tmux session. See Restoring a TTY Session.
Optional: If files were saved with the snapshot, check the Force overwrite files Checkbox box to overwrite the current versions of those files on the filesystem.

Warning: The overwritten files are not recoverable.

Important: If any of the files exist and you do not choose to overwrite them, the restore fails.
In the Snapshot Information Dialog, click Restore.
The Restore Instance Dialog shows the snapshot's memory profile, log trace status, and the MemVerge Memory Allocation Service communication port.
In the Restore Instance Dialog, click Restore.
