Install and Configure OLAP Interface

Use Visual KPI Server Manager to install and configure an OLAP interface. An OLAP interface can be installed on Visual KPI Server or on any machine that is available to the Visual KPI Server via HTTP. If the interface is being installed on a machine other than Visual KPI Server, you need to first install Visual KPI Server Manager.

Install OLAP Interface

During the interface install, use the Back button to move to a previous page in the installation wizard, or use the Cancel button to cancel the installation process.

  • Open Visual KPI Server Manager.
  • Expand the Sites folder. If you have Visual KPI sites defined on your system, they are displayed here. Expand the site in which you want to install the interface. Continue expanding the site’s hierarchy until Interfaces is selected.

  • Right-click Interfaces and select Install New Visual KPI Interface/OLAP Interface. The Interface Setup Wizard opens.
    install OLAP interface
  • Click Next to continue. The License Agreement page displays.
    install OLAP interface
  • Select the I accept the terms of the license agreement option and click Next to continue. The OLAP Interface Name page displays.
    install OLAP interface
  • Accept the Visual KPI OLAP Interface Name, or change it to meet your requirements. The Visual KPI OLAP Interface Name is used to set the defaults for the Installation Path and Virtual Directory Name during this installation.
  • Click Next to continue. The Installation Path page displays.
    install OLAP interface
  • Accept the default installation path, or change it to meet your requirements.
  • Click Next to continue. The Connection String page displays.
  • Update the Connect String to meet your requirements. You can use the drop-down list to select sample connect strings, which you can then modify. For example connect strings, see Using Connect Strings with the OLAP Interfaces.
  • You can opt to verify the connection before proceeding.
  • Click Next to continue. The Ready to Install page displays.
    install OLAP interface
  • Click Next to install the interface. The Finish page displays.
    install OLAP interface
  • Click Finish to close the Setup Wizard. The newly installed interface displays in the Interfaces folder.OLAP interface

The installation of the OLAP interface is now complete.

Configure an OLAP Interface

If you need to change the configuration settings for your OLAP interface after it has already been installed, use Visual KPI Server Manager.

  • Expand the Sites folder. Expand the site that includes the interface to be configured.
  • Under the Interfaces folder, select the OLAP interface to be configured. The detail pane displays the interface’s current configuration.configure OLAP interface
  • Mouse over a setting to display a tooltip with the current configuration for that setting, if the value is not already displayed in its entirety.

Modify Settings

You can modify any of the configuration settings that are not grayed out.

  • To make changes to Log Name and Connect String, double-click the setting name to select the setting’s value, or click in the setting’s cell, and enter the new value. For example connect strings, see Using Connect Strings with the Interfaces
  • To make changes to Get Current Data Query, Get Trend Data Query or Get Historical Value Query, click in the cell and enter the new query, or click the down arrow to open a larger text entry field. Press the Enter key to start a new line. Press Ctrl + Enter to close the field and accept the text you have entered.
  • To make changes to the Log Level, select an appropriate level from the list. You can select Errors OnlyModerate or Full. Learn more about how to Configure the Error Logging Level.
  • To adjust for the database being a different timezone than the Web server, make changes to the Database Time Zone.
  • To adjust for data using commas instead of decimals, make changes to the Database Locale.
  • To make changes to the date time format that reflects your data, change the Date Time Format. 24-hour clock format is shown as uppercase YYYY-MM-DD; 12-hour format is in lowercase yyyy-mm-dd. Trend queries that do not display data often have a mismatched Date Time format when compared to the data format.

After making any required changes, click Apply to save the changes. Make sure the connection is working.

Verify an OLAP Interface Connection

Once you have installed and configured the OLAP interface, you should verify the interface is able to connect to the database. You can use Visual KPI Server Manager to verify the connection.

  • Expand the Sites folder. Expand the site that includes the interface to be verified.
  • Right-click the OLAP interface and select Verify Connection. A message displays indicating the connection was successful, or if the connection failed, a message displays indicating the failure:
    verify OLAP interface
  • Click OK in the message.
  • If there were any errors, make the required changes to the Connect String and/or Queries and repeat the verification.

Note: It is important to note that verifying the connection does not ensure proper security has been implemented. To ensure you can access the data within the database, you should test the OLAP interface connection.

TEST AN OLAP INTERFACE CONNECTION

Once you have verified the OLAP interface connection, you should test the connection to ensure you can access the data within the database. Use Visual KPI Server Manager to test the connection.

  • Expand the Sites folder. Expand the site that includes the interface to be tested.
  • Right-click the OLAP interface and select Browse. Your browser opens and displays the OLAP Interface Web Service page.OLAP interface
  • Click any of the Test links.test OLAP interface
  • In the LookupValue field, enter a valid lookup name and click the Invoke button. A new instance of your browser opens.
  • Look for the “<NewDataSet xmlns=””>” entry. Within this entry are the results of the test. If the connection and security settings are valid, a value is returned. Otherwise, an error is displayed as the value.
  • If there are any errors, make the required changes to the Connect String and/or Queries and repeat the test.
