Creating a SQL-based data mart for a custom view in the TrueSight console
Using the Data marts wizard, you can build a custom data mart to retrieve the data according to your requirements for a custom view in the TrueSight console. You can configure the data mart based on the following options:
- Decide on the type of content to be displayed by the data mart
- Identify the primary entity of the data mart
- Apply required sorting options
- Configure the filters to be displayed in the TrueSight console
- Set the materialization type and schedule
- Configure role-based access
You can either create a simple data mart or an advanced data mart (with the required filters, output columns and custom role-based access restrictions).
The following video (3:48) illustrates the process of creating a SQL-based custom data mart that can be used to build a custom view in the TrueSight console.
Steps for creating a data mart for a custom view using the basic options
Before you begin
Access the Data marts page. For more details, see Managing data marts for custom views, reports, and report templates .
To add a data mart for building a custom view in the TrueSight console
On the Data marts list page, select Add > Data mart based on SQL.
The Data marts wizard is displayed.
On the Welcome page, under the Purpose of data mart, select Build Capacity View in TrueSight Console.
Under the Content of data mart, select one of the following options:
- Summary information for a set of entities: Adds a data mart that provides a summary information about the entities returned by the SQL query.
- Time series details for a set of entities: Adds a data mart that provides a time series details about the entities returned by the SQL query. When you select this option, columns returned by SQL query are checked to ensure that one column contains Timestamp set as the Meaning. This is automatically detected when the query is executed or can be manually set for the required column in the Columns page.
- Click Next.
On the Definition page, set values for the following properties:
Primary entities: Select any one of the following options:
- System: Performs a check on the columns extracted by the query to identify whether one or more columns contain System Identifier as the meaning.
- Business driver: Performs a check on the columns extracted by the query to identify whether one or more columns contain Workload Identifier as the meaning.
- Domain: Performs a check on the columns extracted by the query to identify whether one or more columns contain Application Identifier as the meaning.
Other
SQL Query: Type SQL query to retrieve the required data by selecting the required columns of a table.
Tip
To display filter for the columns in the view in the TrueSight Console, you can use a query that contains a filter macro. For more details about filter macro, see Using filter macros with SQL queries.
For the proper data mart column names, BMC recommends to use the Labels option in the Output Columns section instead of using table column aliases in the SQL query.
Click Next.
On the Columns page, modify the properties of the columns in the data mart. These properties will be used and displayed on the custom view page where the data mart is used.:
In the Output Columns section:
To modify the label, meaning, or filter behavior of a column, click the name of the required column and specify the values.
By default, the Basic properties are displayed in the editor. For viewing the Advanced properties, select the Advanced option.
If you want to use this data mart in a custom view that uses the Link renderer with page parameters, you must specify the Meaning value for each page parameter. Otherwise linking with page parameters does not work.
For example, you want a custom view that shows a table with all the virtual machines in your infrastructure and the view page should have a provision to link to the details of each VM.
To do so, you need to configure a custom view page (VM Overview) to show a table with a list of VMs and a custom view page (VM Details) to show the VM details. The VM Details page is created using the System details template, which supports sysid as the page parameter.
- In the data mart that is used for the VM Overview page, select System Identifier as the Meaning of the sysid column.
- In the custom view configuration, set the renderer for the VM Name column to Link and select the target view page as VM Details.
When you click on a VM Name link in the VM Overview page, the page parameter sysid is used to identify the VM whose name is clicked and the VM Details page with the corresponding VM's information is displayed in the VM Details page.
Note that the parameter is added as a suffix to the target view page URL as shown in the following screenshot.
You can select one of the following options from the Meaning list.
Meaning option Description Output column Value Select this option if the output column contains a value that is a statistic derived from a metric. Following options are displayed when you select Value as the Meaning: - Related to metric: Select the required metric type to which this value in the output column is related. After you select the required metric type, select required metric from list. If there is no metric with which the output column can be associated, select None.
Unit of measure: When you select a metric in the Related to metric, the associated option is set in the Unit of measure. If the Related to metric is set to None, select the required option from the Frequently used drop-down list, or select Other and type the required unit of measure in the box for the value in the output column.
For example, if the Related to metric is CPU Utilization, the Unit of measure is set to %.

In the Sorting Options section, select the required columns from the Source table, and add them to the Selection table using the >>DESC or >>ASC button to sort the data in the descending order or ascending order respectively. In the Selection table, select the required column, and add them to the Source table by using the << button. You can also change the order of display of columns added to the Selection table by using the Up or Down arrow buttons.
In the Time period label box, type the required label for data mart that are not sensible to time filter. This field is displayed only when there are no time filter macros defined for the data mart or there no columns that have the meaning set as Timestamp. When the data mart is not sensible to time filter, the the time filter for the selected custom view built using this data mart is disabled and this label is displayed in the selected view.
In the Detected filters section, perform the following steps:
- Click the name of the filter.
- In the Editor of the filter name page, edit the Label and Description of the filter.
Click Apply.
- Specify the required unit of measure. You can choose from the Frequently used list or select Other and type the required unit of measure in the box for the value. This field is displayed only when the column contains numeric value.
On the Materialization page, specify the following details:
Materialization option Description Always see fresh data
Select this option to load fresh data every time you access the associated view in the TrueSight console. Note: Every time the SQL query runs, it fetches data directly from the database. Hence, a complex query might require more time to run and the performance might be impacted.
Create materialized table
Select this option to load materialized data in the associated view in the TrueSight console.
This option is useful when you have a complex SQL query and you want to see or use the fetched data quickly. The data mart is materialized and the data is stored in a new table, which is shown whenever you choose to Preview or view the data.
Specify the following settings:
From the Materializer task list, select the task to be used for materializing the data mart. You can select from the available out-of-the-box tasks or create a new one. For more information about creating a materializer task, see Configuring the Data Mart Materializer task.
Tablespace Enter the name of the tablespace where the generated table is materialized. If no value is specified, the default tablespace of the product is used. Materialize validity Enter a number and select hour, day, or week to specify the time validity of the materialized data mart.
The data mart is not re-materialized if you run the associated materializer task again while the time specified in this field is still valid.
For example: Consider data mart A with Materialize validity of 6 hours. The associated materializer task for this data mart runs daily at 5 A.M.
If the associated materializer task runs again at 10 A.M., the data mart A is not re-materialized because the time specified in the Materializer validity field is still valid.
Index count Select the number of blocks of indexes that you need. You can choose maximum 4 blocks.
For each index block, in the corresponding Index # columns field, select the indexes from the Source list and move them to the Selection list by using the
button.And, enter the Index # tablespace name.
(Advanced only): To specify access permissions to DB users and DB roles to the materialized table in the database, configure the following advanced settings:
Field Description Grant to DB users Select the database users from the Source table, and add them to the Selection table using the 
button.Grant to DB roles Select the required database roles from the Source table, and add them to the Selection table using the button.Grant to user specified roles Type the required user specified (defined) roles separated by semi-colon to give them permissions to use this data mart. On the Name page, specify the following details:
Field Description Name Type the required name for the data mart.
Identifier Indicates the unique identifier for the data mart. Every identifier is prefixed with 'ER_V_'. By default, the identifier is suggested based on the data mart name. You can edit this value. The identifier must contain only letters, numbers or underscores, and it cannot be empty. This identifier can be used in the SQL query while creating dependent data marts.
Note: If you modify the identifier of the data mart that is currently in use by one or more data marts, the dependent data marts will stop working. A warning message is displayed with a list of dependent data marts. You can choose to revert the changes or proceed with the update. If you choose to proceed, you must update the identifier in the dependent data marts to continue to use them.Description Type the required description for the data mart. Click Finish.
The new data mart is added in the Data marts list page and can be used to build a view in the TrueSight console.
