Managing Containers

This screen displays Containers hosted on all the Hardware Nodes that have been registered in Parallels Infrastructure Manager by now.

The information, such as the IP addresses, hostnames, statuses of all the Containers, presented in the Containers table is displayed according to the settings made on the Select Columns drop-down menu. If all the columns are selected, this table presents the following:

Column Name

Description

ID

The ID assigned to the Container.

Name

The name of the Container.

Hostname

The hostname of the Container.

Description

The description of the Container.

IP Address

The IP address(es) assigned to the Container.

Hardware Node

The hostname or IP address of the Hardware Node where the Container is hosted.

Technology

The virtualization solution the Container is based on. Currently Infrastructure Manager allows you to manage Virtuozzo-based Containers; it will support other virtualization technologies in the future.

Platform

The operating system installed on the host Hardware Node.

Architecture

The microprocessor architecture of the host Hardware Node.

Operating System

The OS template the Container is based on.

Original Sample

The Container sample the Container is based on. The asterisk after the sample name indicates that the Container sample has been customized by changing one or several QoS parameters.

CPU

Presents a visual representation showing how much host Hardware Node CPU time the Container is consuming at the moment.

Disk

Presents a visual representation showing the current host Hardware Node disk space consumption by the Container.

Memory

Presents a visual representation showing the current consumption of the memory resources allocated to the Container.

Alert

Every time a Container consumes more of a resource than is specified by the limit on that resource, or is coming close to that limit, an alert is generated and logged. The green, yellow, or red circle in this column indicates the cumulative resource consumption by the Container. For a more detailed QoS alerts description, refer to the Monitoring Container Principal Resources section.

Enabled

A green tick opposite a Container indicates that this Container is enabled and can be started, a red cross means that the Container is disabled and cannot be started.

Status

The current status of the Container.

Note: The CPU, Disk, and Memory columns provide a simplified representation that gives you a very general idea of the current resource consumption. The information is retrieved every 10 seconds and Parallels Infrastructure Manager displays the latest values. To have a more comprehensive resource consumption report for a Container, click its name to open the Container dashboard and open the Resources tab where you need to click the Overview link to open the screen displaying a minute resource consumption description.

To facilitate working with Containers residing on your Hardware Node, you may have the Containers table display only those Containers that conform to particular parameters. Above the table, click the Show Search link to display the fields where you can specify the parameters the Containers should meet; you can also customize these fields by clicking Customize. Then click on the Search link. To view all the Containers residing on your Hardware Node, click on the Reset Results link to the right of the parameter fields.

To manage several Containers at once, make use of Infrastructure Manager toolbar right above the table. You are able to execute the following operations on Container groups:

To perform anything of the above, select the checkboxes opposite the corresponding Containers and press the appropriate link on the Infrastructure Manager toolbar.

Many more operations can be performed on a single Container through the corresponding Container dashboard.
