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.
Managing Memory Machine Snapshots
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.
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.

Overview and Installation
Understanding how persistent memory works is helpful when getting started with MemVerge Memory Machine. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.

- 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.
  - Managing Memory Machine Snapshots
    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 Tools
You can administer and use MemVerge Memory Machine using a Command Line Interface (CLI).
Memory Machine Administration
MemVerge Memory Machine can be installed and run using CLI commands. Many administrative tasks can be performed using the Memory Machine Management Center web interface.
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 TTY Session

If a restored application instance has a TTY session, Memory Machine Management Center (M3C) opens the session using the tmux utility.

Before you begin

Install tmux version 1.8 or higher. The tmux utility must be in the execution path on the data host where you restore the session.

Capture a snapshot of an application with a command-line interface, for example a Redis client console. See Capturing a Snapshot Using Memory Machine Management Center. Then stop the application instance; see Stopping an Application Instance.

About this task

Procedure

In the Applications Console, choose the application instance that you want to restore.
In the Snapshot Timeline, choose the snapshot to restore.
Choose Restore.
Optional: If the application instance has an attached TTY, the Restore Instance Dialog shows the Tmux Session Textbox. Enter a name for the tmux session.
If you do not enter a name, the system assigns the application instance's PID to the tmux name.
Click Restore.
When the process has been restored, click the Tmux Session Tab.
Click the Copy Icon next to the Attach Command.
Paste the command into a terminal window and press Enter.

Important: You must have permission to access the tmux socket file path. We recommend that you log in as (or su to) the owner of the socket file path before connecting to the session.

The application's command line interface is restored in the terminal window.
