About the Namespaces page

o view, create, and manage namespaces, you use the Namespaces page in the Tenant Management Console. To display this page, in the top-level menu, click Namespaces.

The Create Namespace bar on the Namespaces page shows the number of bytes of storage used in all the tenant's namespaces, along with a graphical representation of the amount of storage used out of the hard quota for the tenant. It also shows the number of bytes of storage available for storing more objects in the tenant's namespaces.

The Namespaces page also lists the namespaces owned by the current tenant.

Roles: To view the Namespaces page, you need the monitor, administrator, or compliance role.

Understanding the namespace list

The Namespaces page contains a list of the namespaces owned by the current tenant. For each namespace, the list shows:

  • The namespace name.
  • The number of objects currently in the namespace. Each version of an object counts as a separate object. However, the object count does not include object versions that are delete markers.

    Each multipart object counts as a single object. Objects that are in the process of being created by multipart uploads are not included in the object count.

  • Icons for any current alerts that apply to the namespace. Alerts indicate conditions that may need your attention. To see the text that accompanies an alert icon, hover over the icon.
  • The number of bytes of storage used out of the hard quota for the namespace, along with a graphical representation of the amount of storage used.

    Used storage includes storage occupied by the parts of in-progress multipart uploads that have already been written to the namespace. Used storage does not include replaced parts of multipart uploads, parts uploaded for aborted multipart uploads, or unused parts of completed multipart uploads.

NoteReplaced parts, parts of aborted multipart uploads, and parts not included in completed multipart uploads are deleted automatically but not necessarily immediately.

To view additional information about an individual namespace, click the namespace name.

Managing the namespace list

By default, the namespace list on the Namespaces page includes all existing namespaces. The namespaces are listed 20 a time in ascending order by namespace name.

You can page through, sort, and filter the list of namespaces. The Namespaces page indicates which namespaces are shown out of the total number of namespaces in the current list.

Paging

You can change the number of namespaces shown at a time on the Namespaces page. To do this, in the Items per page field, select the number of namespaces you want. The options are 10, 20, and 50.

To page forward or backward through the namespace list, click the next (GUID-E53D8EEE-3705-4C3C-B18A-BEB5FB24120A-low.png) or back (GUID-18C7E4A4-FD0B-42E4-B8A2-398D820683E9-low.png) control, respectively.

Procedure

  1. In the Page field, type the page number you want.

  2. Press Enter.

Sorting

You can sort the namespace list in ascending or descending order by namespace name or by hard quota. To sort the list, click the column heading for the property you want to sort by. Each time you click the column heading, the sort order switches between ascending and descending.

Filter using filter fields

You can filter the namespace list by namespace name or tag. The filtered list includes only those namespaces with a name or tag, as applicable, that begins with a specified text string.

You can filter the namespace list by name or by tag by using the fields above the list.

Procedure

  1. In the field above the Name column, select Name to filter by name or Tag to filter by tag.

  2. In the next field, type the text string you want to use as a filter.

    This string can be up to 64 characters long, can contain any valid UTF-8 characters except commas (,), and is not case sensitive. White space is allowed.
  3. Click the find control (GUID-6E913982-4DF5-4877-8C35-9F689D3C126D-low.png).

Next steps

To redisplay the entire list of namespaces after filtering it, click the clear filter control (GUID-2642447B-5A00-4823-9C72-F52C8FB6018E-low.png).

Filter using tag control

  1. Click the tag control (GUID-DC59DF92-A92F-457B-8A8E-72034AEF04E5-low.png) on the right above the namespace list.

    The Tags window opens. This window lists all the tags currently associated with the existing namespaces owned by the current tenant. For each tag, the window shows the number of associated namespaces.
  2. Click the tenant-count icon (GUID-D2C90165-8D35-47E7-BA1C-8D1EA272E7B8-low.png) for the tag you want.

    The namespace list shows only the namespaces that have the selected tag, and the fields above the Name column show the filter criteria.

Namespace Overview panel

The namespace Overview panel shows the current status of any given namespace.

Display the namespace Overview panel

Before you begin

To view the namespace Overview panel, you need the monitor, administrator, or compliance role.

Procedure

  1. In the top-level menu of the Tenant Management Console, click Namespaces.

  2. In the list of namespaces, click the name of the namespace you want.

Next steps

To return to the namespace Overview panel from other namespace panels, click Overview in the row of tabs below the namespace name.

Namespace URL

The top of the namespace Overview panel shows the URL for access to the namespace content through the HTTP protocol. If the HTTP protocol is enabled for the namespace, this URL is a link that opens the Namespace Browser for the namespace.

A namespace URL has this format:

https://namespace-url-name.tenant-url-name.hcp-domain-name

For example, the URL for access to the content of the Accounts-Receivable namespace owned by the Finance tenant in the HCP system named hcp‑ma.example.com is:

https://accounts-receivable.finance.hcp‑ma.example.com

If SSL security is not enabled for the HTTP protocol, the URL contains http instead of https.

NoteThe HCP domain name used for access to namespace content may not be the same as the domain name used for access to the tenant for management purposes. Be sure to give your namespace users the correct domain name.

Similarly, the IP addresses for the system may differ for these two purposes. For the IP addresses to use for namespace access, contact your HCP system administrator.

Namespace owner

The top right corner of the namespace Overview panel shows the namespace owner if the namespace has an owner:

  • If the owner user account is an HCP account, the panel shows the account username.

    If the user account for the owner of a namespace is deleted, the namespace reverts to having no owner.

    • HCP can retrieve the user account information from AD, the panel shows the account username along with the name of the AD domain in which the account is defined, in this format: username@ad-domain-name
    • HCP cannot retrieve the user account information from AD, the panel shows the SID for the user account. This can happen if the AD user account was deleted or if HCP cannot communicate with AD.

In either case, the username or SID is a link that you can use to change the namespace owner. If the namespace has no owner, the top right corner of the panel shows the Modify Owner link, which you can use to assign an owner to the namespace.

Objects section

The Objects section in the namespace Overview panel contains a graph showing the number of objects in the namespace during the past 30 days (or since the namespace was created if that was less than 30 days ago).

Each version of an object counts as a separate object. However, the object count does not include object versions that are delete markers.

Each multipart object counts as a single object. Objects that are in the process of being created by multipart uploads are not included in the object count.

While any of the search facilities is selected for use with the Search Console, the graph also shows the total number of indexed objects in the namespace during the past 30 days. For any point in time for which the indexed object count is shown, the count reflects the index maintained by the search facility that was selected for the Search Console at that time.

Note
  • If the HDDS search facility is selected for use with the Search Console, the graph shows the number of indexed objects only if that facility is configured to show statistics.
  • For any period during which HCP cannot retrieve statistics from the HDDS server (for example, because the network connection is broken), the graph shows the number of indexed objects as zero.

The x‑axis in the Objects graph marks the passage of time. The y-axis marks the number of objects. As the number of objects increases, the intervals on the y-axis get larger. The section heading indicates the current measurement unit (for example, thousands or millions).

The graph legend shows the most recent value for the number of objects stored (Ingested object count) and, if applicable, the number of indexed objects (Indexed object count).

Below the Usage section, which is below the Objects section, the Overview panel shows the date and time the Objects and Usage sections were last updated. To show the most current information in these sections, click Refresh Now.

Usage section

The Usage section in the namespace Overview panel contains a graph showing information about the namespace storage during the past 30 days (or since the namespace was created if that was less than 30 days ago).

The x-axis in the Usage graph marks the passage of time. The y-axis measures the amount of storage in gigabytes, terabytes, or petabytes, depending on the namespace size. The graph heading indicates the current measurement unit (gigabytes (GB), terabytes (TB), or petabytes (PB)).

The Usage graph shows:

  • Total storage capacity

    The hard quota for the namespace.

  • Used storage capacity

    The total amount of storage space currently occupied by all data stored in the namespace, including object data, metadata (except ACLs), and any redundant data required to satisfy the namespace service plan.

    Used storage includes storage occupied by the parts of in-progress multipart uploads that have already been written to the namespace. Used storage does not include replaced parts of multipart uploads, parts uploaded for aborted multipart uploads, or unused parts of completed multipart uploads.

    NoteReplaced parts, parts of aborted multipart uploads, and parts not included in completed multipart uploads are deleted automatically but not necessarily immediately.
  • Ingested volume

    The total size of the stored data and custom metadata before it was added to the namespace. This value tells you how much data you have stored.

The graph legend shows the current value for each item.

Below the Usage section, the Overview panel shows the date and time the Objects and Usage sections were last updated. To show the most current information in these sections, click Refresh Now.

Major namespace events

The Major Events section in the namespace Overview panel lists log messages about major events related to the namespace (for example, the amount of storage used by the namespace exceeds the namespace soft quota). The list includes all such messages that have occurred since the namespace was created.

The list of messages in the Major Events section is a subset of the messages in the event log for the namespace. You can view all the messages in the namespace event log in the All Events panel for the namespace.

By default, the messages in the Major Events section are listed ten at a time in reverse chronological order.

If the Overview panel shows alerts instead of log messages, click the Major Events tab to display the log messages.

Namespace alerts

The Alerts section in the namespace Overview panel shows alerts that indicate namespace-related conditions that may require human intervention (for example, the namespace is running low on unused space). This section is visible only if alerts currently exist for the namespace.

Each alert is represented by an icon accompanied by descriptive text.

If the Overview panel shows log messages instead of alerts, click the Alerts tab to display the alerts.

Namespace features

The Overview panel for a namespace shows which of these features are currently enabled for the namespace:

  • Replication

    If this feature is present, the namespace is included in replication of its owning tenant. If this feature is not present, the namespace is not included in replication of its owning tenant.

  • Search

    If this feature is present, search is currently enabled for the namespace. The namespace is searchable if its effective permission mask includes search. If this feature is not present, the namespace is not searchable.

  • Versioning

    If this feature is present, users and applications can create multiple versions of objects in the namespace. If this feature is not present, the namespace does not support versioning.

Additionally, the Overview panel shows:

  • The service plan in effect for the namespace.

    This feature is present only if the tenant is allowed to associate service plans with namespaces.

  • The retention mode of the namespace.

    This is either enterprise or compliance.

  • The cryptographic hash algorithm for the namespace.
  • The DPL for the namespace.

Namespace permission mask

The Permissions section in the namespace Overview panel shows:

  • The permissions included in the inherited mask, which is the effective tenant permission mask.

    These permissions are indicated by gray dots.

  • The permissions included in the namespace permission mask.

    These permissions are indicated by orange dots.

  • The permissions included in effective permission mask for the namespace.

    These permissions are indicated by checkmarks.

Namespace description

The Description section in the namespace Overview panel shows the description of the namespace, if a description exists.
