Azure SQL Top Tables Test

When faced with a disk space crunch, administrators may want to know which tables on the target Azure SQL database have grown beyond permissible limits. The Azure SQL Top Tables test provides administrators with this information.

The test identifies the tables in the target Azure SQL database that exceed a configured size limit, and reports the count of such ‘large sized tables’ . You can use the detailed diagnosis of the test to know which tables in the database are of a large size.

Target of the test : A Microsoft Azure SQL database

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Azure SQL database that is configured for monitoring

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.

Port

The port at which the specified Host listens.

Database Name

Specify the name of the Azure SQL database that is to be monitored.

User Name and Password

Against the User Name and Password parameters, specify the credentials of the user who is vested with DBOWNER rights to the configured Database Name.

Confirm Password

Confirm the specified Password by retyping it here.

SSL

If the Azure SQL database service being monitored is SSL-enabled, then set the SSL flag to Yes. If not, then set the SSL flag to No.

Domain

By default, none is displayed in this text box. If the ‘SQL server and Windows’ authentication has been enabled for the Azure SQL database being monitored, then the Domain parameter can continue to be none. On the other hand, if ‘Windows only’ authentication has been enabled, then, in the Domain text box, specify the Windows domain in which the monitored database exists. Also, in such a case, the User Name and Password that you provide should be that of a 'domain user' with DBOWNER rights to the configured Database Name.

IS NTLMv2

In some Windows networks, NTLM (NT LAN Manager) may be enabled. NTLM is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users. NTLM version 2 (“NTLMv2”) was concocted to address the security issues present in NTLM. By default, this flag is set to No, indicating that NTLMv2 is not enabled by default for the target Microsoft Azure SQL database. Set this flag to Yes if NTLMv2 is enabled for the target database.

Table Size GB

By default, this parameter is set to 10. This means that, by default, this test monitors only those tables in the target database that are of a size greater than 10 GB. You can override this default value if you so need, by providing any value of your choice here.

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 enable/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

Maximum table size

Indicates the maximum size of all the tables that are exceeding the configured TABLE SIZE GB.

GB

Use the detailed diagnosis of this measure to know which tables are hogging the table space.

Table count

Indicates the number of tables that are currently of a size greater than the value configured against the TABLE SIZE GB parameter.
