Containers

View the information that is shown about containers in object storage systems.

A container is the second-level element, under accounts, in the object hierarchy for OpenStack Swift-compliant object storage systems, such as IBM Storage Scale System. A container is equivalent to a directory or folder in a file system and is used to store and manage objects.

The accounts and the containers that you can monitor in the GUI are determined by the role that is associated with your login account for the storage system.

To monitor all of the accounts and the containers, you must be assigned the role that is defined in the reseller_admin_role configuration option in the Swift proxy server. The default value for the reseller_admin_role option is ResellerAdmin.

Tip: To change the credentials for monitoring the storage system, go to Resources > Object Storage Systems, right click the storage system, and then click Connections > Modify Connection.

Additional information is provided about the following column headings:

Capacity Quota (%)

The percentage of the capacity quota for the container that was used when data was collected for the storage system. The quota limits the amount of file system capacity that can be used by the container. This column contains a value only if a capacity quota is defined for the container on the OpenStack Swift object storage system.

The capacity quota is represented by a bar. The percentage of the quota that is used by the container is represented by the blue section of the bar and as a percentage figure on the bar. The available capacity for the container is represented by the light gray section of the bar.

If the used capacity value exceeds the capacity quota, the bar is shown in red and the quota value is represented by a vertical line on the bar. In this case, the percentage figure on the bar exceeds 100%.

The used capacity can exceed the capacity quota in the following cases:

When the capacity quota is set after the object files are uploaded to the file system
When an object file without size information is uploaded to the file system

If a capacity quota value of zero is defined, the capacity quota bar is shown in red and a usage percentage value is not shown.

Capacity Quota (GiB)

The amount of file system capacity that can be used to store object data for the container. This column contains a value only if a capacity quota is defined for the container on the OpenStack Swift object storage system.

Fileset

The top-level GPFS fileset that is associated with the object storage system.

Objects

The number of objects in the container.

An object stores data content, such as files, videos, images, virtual machine snapshots, and other unstructured data. In IBM Storage Scale System, objects are stored as files on the GPFS file system.

Objects Quota

The number of objects that can be stored in the container. This column contains a value only if an objects quota is defined for the container on the OpenStack Swift object storage system.

Objects Quota (%)

The percentage of the objects quota for the container that was used when data was collected for the storage system. The quota limits the number of objects that can be stored in the container. This column contains a value only if an objects quota is defined for the container on the OpenStack Swift object storage system.

The objects quota is represented by a bar. The percentage of the quota that is used by the container is represented by the blue section of the bar and as a percentage figure on the bar. The number of available objects for the container is represented by the light gray section of the bar.

If the number of objects that are used exceeds the objects quota, the bar is shown in red and the quota value is represented by a vertical line on the bar. In this case, the percentage figure on the bar exceeds 100%.

The number of objects that are used can exceed the objects quota if the quota is configured after the object files are stored on the file system.

If an objects quota value of zero is defined, the quota bar is shown in red and a usage percentage value is not shown.
