Configuring near-term history data collection for an application

You can configure Enhanced 3270UI near-term history data collection for application-specific attribute groups. You can specify that the data for the attribute groups is collected over specific Managed Systems and Managed System Lists. You can also specify whether the data is stored at the monitoring server or at the monitoring agents. Storing data at the monitoring agents is preferred. The historical configuration procedure creates Tivoli Monitoring situations that are employed to control historical data collection.

Before you begin

Go to an application-specific workspace and select View > History Configuration from the menu bar, or select an application to configure for Near-term History. For more information about selecting an application to configure for Near-term History, see Selecting an application to configure for Near-term History. After you do one of these actions, the Historical tables configuration workspace opens. The attribute groups that can be configured for near-term history data collection for your chosen application are listed in the workspace.

Restriction: You cannot use the procedure that is described here to change or delete historical data collections that use Tivoli Data Warehouse. Collections that use Tivoli Data Warehouse are configured with another interface, such as the Tivoli Enterprise Portal. If you do try to change or delete collections that use Tivoli Data Warehouse, a pop-up message warns that you cannot configure the collection with the enhanced 3270UI. Use the Tivoli Enterprise Portal to change or delete such collections.

1. Place your cursor before the attribute group name that you want to configure for near-term history data collection and press Enter.
   The OMEGAMON History Configuration workspace opens. The view defaults to the General tab.

   

2. Enter a name for this data collection in the Collection Name field and press Enter.
3. Select the Interval time that you want for this collection, by placing your cursor before an interval time, typing s, and pressing Enter.
   The selected interval changes color.

   
4. The location of the collection might be configurable. If so, the following shows in the middle of the screen:
   
   Select the Collection Location by placing your cursor before TEMA (monitoring agent), or TEMS (monitoring server), and pressing Enter.
   In many cases, the location is predetermined for many attributes. In this case, the view looks as follows:

   

   or

   

   In this case, no selection can be made. If the Tivoli Enterprise Portal was used to create the collection, it is possible that collection is configured in a way that cannot be replicated by the TOM. In this case, the following can occur.

   

   No changes are allowed to this collection.
5. Select the Distribution tab and press enter to go to that tab.
   The Distribution tab opens.

   

   Use this tab to set up your data collection to run either on specific Managed Systems or for a Managed System List.

   Tip: Specifying a Managed System List usually indicates collection for one or more Managed Systems.
6. Select one or more Managed Systems or Managed System Lists for your collection by placing your cursor before the system or list name, typing s, and pressing Enter.
   The selected distribution's collection status changes from Excluded to Including to indicate that you are including them in the collection.

   
7. To save your collection, place your cursor over OK and press Enter. To exit without saving your collection, place your cursor over CANCEL and press Enter. Alternatively, if you navigate away from the General or Distribution tabs, your changes will not be saved.
