Tenant Storage Test

Tenant is a term used for an Office 365 Organization. It is a sandboxed environment for your and your assets. It is within the overall O365 Data Center and is the container for items of your Organization such as users, domains, subscriptions etc.

Typically, server resources such as CPU and RAM are allocated to an Office 365 tenant as a whole based on the number of user licenses; these resources are then shared by all site collections in the tenant. This means that there is the danger of a single site collection exhausting the resources across the tenancy. To avoid this, organizations that have customized site collections or sandboxed solutions use resource quotas. By applying resource quotas to specific collections, administrators can ensure that custom code running in specific site collections does not deplete all server resources assigned to the tenancy.

Like CPU and RAM, storage resources are also allocated to a tenant based on the number of user licenses associated with that tenancy. This storage can then be allocated to the site collections in one of the following ways:

  • Automatically, using pooled storage
  • Manually, by explicitly configuring storage allocations on a per-site collection basis

Regardless of what the resource is (CPU, memory, or storage) and how it is allocated to site collections, it is important that administrators know the total server resource pool/quota and storage quota set for a monitored tenant, and also track how much of the tenant's resources have been assigned/allocated to site collections. This insight will enable administrators proactively detect a potential server/storage resource shortage on the tenant and promptly prevent it by tweaking the quota setting. The Tenant Storage test provides administrators with this useful insight!

This test reports the server and storage resource quotas that have been set for the monitored tenant, and also tracks how much of these resources have been assigned/allocated to site collections. This way, the test reveals whether/not the quotas set for the tenant are adequate, thus urging administrators to fine-tune the quota settings (if required) to avert any resource contention. Additionally, by reporting the count and details of sites deleted, the test also sheds light on how much storage and server resources the deleted sites have released. This information provides useful pointers to administrators for fine-tuning the quota setting.

Target of the test : Microsoft SharePoint Online

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Office 365 tenant being monitored

Configurable parameters for the test

Parameters Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured. By default, this is portal.office.com

O365 User Name, O365 Password, and Confirm Password

For execution, this test requires the privileges of an O365 user who has been assigned the Service support admin and SharePoint admin roles and is vested with the View-Only Audit Logs permission. Configure the credentials of such a user against O365 User Name and O365 Password text boxes. Confirm the password by retyping it in the Confirm Password text box.

While you can use the credentials of any existing O365 user with the afore-said privileges, it is recommended that you create a special user for monitoring purposes using the Office 365 portal and use the credentials of that user here. To know how to create a new user using the Office 365 portal and assign the required privileges to that user, refer to Creating a New User in the Office 365 Portal.

O365 Domain

To have a personalized business email address, team site address, or even an account name, you set up a domain name with Office 365. A domain is a unique name that appears after the @ sign in email addresses, and after www. in web addresses. It typically takes the form of your organization's name and a standard Internet suffix, such as yourbusiness.com or stateuniversity.edu. Office 365 gives you an initial domain name to use. By default, this will be of the format: *.onmicrosoft.com - eg., abc.onmicrosoft.com. To enable this test to pull metrics, you need to configure the test with the name of this initial domain. Therefore, configure the O365 Domain parameter with the name of the initial domain. To know what is your Office 365 initial domain name, do the following:

  1. Log on to the Microsoft Office 365 Online Portal using an administrative account.
  2. Under Management, click on Domains.
  3. The initial domain should be listed with a name ending with .onmicrosoft.com.

Domain, Domain User Name, Domain Password, and Confirm Password

These parameters are applicable only if the eG agent needs to communicate with the Office 365 portal via a Proxy server.

In this case, in the Domain text box, specify the name of the Windows domain to which the eG agent host belongs. In the Domain User Name text box, mention the name of a valid domain user with login rights to the eG agent host. Provide the password of that user in the Domain Password text box and confirm that password by retyping it in the Confirm Password text box.

On the other hand, if the eG agent is not behind a Proxy server, then you need not disturb the default setting of these parameters. By default, these parameters are set to none.

Proxy Host, Proxy Port, Proxy User Name, Proxy Password and Confirm Password

These parameters are applicable only if the eG agent needs to communicate with the Office 365 portal via a Proxy server.

In this case, provide the IP/host name and port number of the Proxy server that the eG agent should use in the Proxy Host and Proxy Port parameters, respectively.

If the Proxy server requires authentication, then specify the credentials of a valid Proxy user against the Proxy User Name and Proxy Password text boxes. Confirm that password by retyping it in the Confirm Password text box. If the Proxy server does not require authentication, then specify none against the Proxy User Name, Proxy Password, and Confirm Password text boxes.

On the other hand, if the eG agent is not behind a Proxy server, then you need not disturb the default setting of any of the Proxy-related parameters. By default, these parameters are set to none.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time the test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enabled/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

OneDrive storage quota

Indicates the OneDrive storage quota.

GB

Total server resource quota

Indicates the total server resource quota.

Number

The server resource quota is a site collection metric calculated by SharePoint Online. The main purpose of server resource quotas is to limit the risk that sand-boxed custom code can have on available resources on a site collection - bad code causing unhandled exceptions or excessive CPU usage are good examples.

Your organization is assigned a total Server Resource Pool that is based on the total number of users. By default when you create a site collection it is assigned a Server Resource Quota of 300. Generally this an acceptable quota. If you do not want to allow any sandbox solutions to be used within your site collection you can set this value to zero (0).

Assigned server resource quota

Indicates the server resource quota that has been assigned to site collections in the monitored tenant.

Number

If the value of this measure is equal to or close to the value of the Total server resource quota measure, it indicates that a huge chunk of the tenant's resources have been assigned to site collections via site collection-specific resource quotas. To ensure that the tenant does not run out of CPU and memory resources, you may want to increase the tenant's server resource pool or the reduce the allocations to the site collections.

Tenant storage quota

Indicates the storage quota of the monitored tenant.

TB

Tenant storage quota assigned

Indicates the storage quota of the tenant that has been assigned to all site collections in the tenant.

TB

If the value of this measure is equal to or close to the value of the Tenant storage quota measure, it indicates that a huge chunk of the tenant's storage resources have been assigned to site collections. To ensure that the tenant does not run out of storage resources, you may want to increase the tenant's storage quota or the reduce the allocations to the site collections.

Deleted sites

Indicates the number of sites in the tenant that have been deleted.

Number

Use the detailed diagnosis of this measure to know which sites have been deleted.

Applications

Indicates the number of applications the tenant hosts.

Number

Use the detailed diagnosis of this measure to know which applications are hosted by the tenant.

Web templates

Indicates the number of web templates in the monitored tenant.

Number

To know which are the web templates, use the detailed diagnosis of this measure.

The detailed diagnosis of the Deleted sites measure lists the deleted sites in the tenant, the current status of each site, when they were deleted, and how much resource and storage quota was released upon their deletion. In the event of a resource contention, if administrators decide to increase the storage and/or server resource quota, then knowing how much resources were freed up by deleted sites will help them figure out how much more resources the tenant will need. The quota can be reset based on this analysis.
