Hardware Node Dashboard Overview

The Hardware Node dashboard provides an overview of the configuration and the current status of the given Node and enables you to quickly launch the most typical server management tasks.

The Server Status table informs you on everything related to resources and updates:

Field	Description
Status	Shows if the Node is running or not.
License	Refers to the state of the Virtuozzo Server license. Click the Install License link if your current license status (a red circle) suggests that you do.
Alerts	Informs you if any of the Containers on this Node consume more of some resource than is specified by the limit on that resource (a red circle) or is coming close to the limit (a yellow circle). To see the resource alerts logs, click the Show link.
Kernel	Displays the number of your OS kernel and informs you about the kernel updates available by following the Check for update link (a yellow circle tells you that kernel updates are possible, a red one - that updating your kernel is critical, a grey one - that there is no information on available updates).
Virtuozzo	Shows you the type of the architecture this Virtuozzo build was made for, the build number and the information on critical (a red circle) and not critical (a yellow circle) Virtuozzo Containers updates. A grey circle shows that there is no information on available updates.
RAM + Swap Usage	The total percentage of the current Hardware Node utilization in terms of both allocated memory and, if swapping is on, swap space.
Disk Usage	The percentage of the available disk space currently in use by the Node.
CPU Usage	The percentage of the CPU power used by the Node at the moment the current Infrastructure Manager page was generated.
Load Average	The last 1, 5, and 15 minutes system load averages.

The Server Configuration table displays the configuration of the Hardware Node:

Field	Description
Group Role	The role of this Node in its Virtuozzo Group. Any Virtuozzo Group consists of one Master Node and one or more Slave Nodes.
Hostname	The hostname of the Hardware Node.
IP Address	Enumerates all the IP addresses the Hardware Node has on all its network interfaces.
Architecture	The description of the processor model(s) installed on the Node.
CPU	The Hardware Node CPU power. If the Node has several processors, the column shows the summation of their powers.
Cores per CPU	The number of cores in each of the CPUs of the Node.
OS	The operating system installed on the Hardware Node.
Uptime	The time that has passed from the last Hardware Node start.

In the Containers section you can quickly assess such Container-related details as the number of running and stopped Containers, see how many are depleting Hardware Node resources, so they had better be paid attention to, and the number of Containers your license allows you to run on the Node.

In the Tasks section to the right of the Server Status section you are provided with a quick access to some of the common server maintenance tasks:

Configuring the default backup settings that will be used for all the Containers on this Node (the Container Backup Settings link). These settings can be overridden individually for each Container on the corresponding screens.
Changing the SMTP relay server IP address and the proxy server address or hostname of the current Hardware Node (the Proxy Settings link). The Node uses the SMTP mail server to send emails. The reasons to establish an email connection may be different, a password reminder or an alert notification among them.
Changing the periodicity of refreshing the resources consumption information in the Virtuozzo logs (the Logging link).
Managing the Service Container (the Service Container link). The Service Container is a special Container running a special service called Parallels Agent that is responsible for managing all the Containers of the given Hardware Node. To learn more about it, refer to the Parallels Virtuozzo Containers User's Guide. If you don't know how to deal with it and why at all, just ignore this link.
Creating a new Container on this Hardware Node (the Create New Container link).
Uploading and installing templates (the Install Template link). A template (or a package set) is a set of original application files (packages) repackaged for mounting over Virtuozzo File System. Application templates are used to install an application or a set of applications in Containers.
Moving the physical server to the Container with the help of the Migration wizard (the Migrate Server to Container link).
Rebooting this Hardware Node (the Reboot Hardware Node link). Keep in mind that usually this process takes 3-5 minutes. During this time, the Hardware Node and all Containers residing on it will be unavailable.
Checking for the available updates for this Virtuozzo Containers installation (the Software Updates link).
Configuring the Hardware Node connection to the Virtual Networks (the Virtual Networks link). A Virtual Network is the grouping of several Containers with bridged network interfaces into a single subnet. Virtual networks are also used to single out groups of Containers on a Hardware Node into separate subnets to be invisible to each other.
Changing the offline management settings of the Hardware Node (the Offline Services link). These settings will be applied to all Containers on the Node. The offline management makes it possible to manage the Containers of the current Hardware Node by means of Parallels Power Panel whatever the Container state.
Connecting to the Node via SSH (the Terminal Login link).
Connecting to the Node via the Remote Desktop terminal (the Remote Desktop link).

The Disk and Memory sections inform you about the respective resources consumption on the Hardware Node. The information on the memory usage is displayed in the following way:

Field	Description
Physical memory	The percentage of the current Hardware Node utilization in terms of allocated memory.
Swap Space	The percentage of the current Hardware Node utilization in terms of allocated swap space. The bar is not displayed if swapping is not configured on the Node.
RAM+Swap	The simple average of the resources above.

The information on the disk size usage in all the partitions or logical disks existing on your Hardware Node is presented in the following tables (corresponding to the number of partitions/logical disks):

Column Name	Description
Mount Point	The name of the partition/logical disk using the resource.
Used	Used amount of disk size in the partition/logical disk
Free	Free amount of disk size in the partition/logical disk.
Total	The total amount of disk size allocated for the partition/logical disk.

The Resources Commitments section provides a summarized information on the disk and memory resources promised to all the Containers hosted on the Node. The Value column displays how much resources has been promised, and the Percentage column - how much of them is currently in use by the Containers. If at least one Container is promised unlimited resources, the Value column shows "Unlimited", and the Percentage column - "n/a" for the corresponding resource.

A more detailed information on the Hardware Node resource consumption is provided in the Monitoring Hardware Node Resources Consumption section.

Apart from the operations available in the Tasks section, the Infrastructure Manager toolbar provides you with access to the following operations:

Changing the Container backup settings (the Container Backup Settings link on the Configure menu).
Changing the proxy settings (the Proxy Settings link on the Configure menu).
Changing the periodicity of refreshing the resources consumption information in the Virtuozzo logs (the Logging link on the Configure menu).
Updating the Virtuozzo Containers installation with the latest Virtuozzo packages (the Software Updates link on the Manage menu).
Reviewing the list of the Virtuozzo Virtual Networks available in Parallels Infrastructure Manager (the Virtual Networks link on the Manage menu).
Configuring the offline management settings of the Hardware Node (the Offline Services link on the Manage menu).
Connecting to the Node via SSH (the Terminal Login link).
Connecting to the Node via a browser-based Remote Desktop client (the Remote Desktop link).
Establishing a private secure connection to the Parallels support team server (the Get Support link).
