To edit information in an existing data source or to remove information in a data source, select the data source on the Agent Information page. The lower part of the page is updated to display the properties for the selected data source. Alternatively, if you are on the last page of the New Agent wizard (the Data Source Information page), you can double-click the data source to launch the Data Source Properties window with the same information as the lower part of the Agent Information page.
Table 5 describes the field information that is applicable to all of the data sources. Use the fields to modify the properties for the data source or attribute selected.
| Field name | Description | Acceptable values and examples |
|---|---|---|
| Data Source name | Name of the data source as it is displayed in the Tivoli Enterprise Portal | Acceptable values: User-friendly descriptive string less than or equal to 32 characters long. It must be unique within the agent. The first character must be a letter and remaining characters can be letters, numbers, or underscores. An underscore is displayed as a space in the Tivoli® Enterprise Portal. Do not use spaces or special characters. |
| Help text | Help text for the data source | Acceptable values: String up 256 characters long. |
| Produces a single data row | The data source returns one row of data. Editable in all sampled data sources. | Example: If monitoring physical system memory, choose a single row, because a system typically manages all of its memory in a single pool; so only one row of data can be returned. |
| Can produce more than one data row | The data source can return any number of rows of data. Editable in all sampled data sources. | Example: If monitoring disk drives, choose multiple rows, because there can be more than one disk in a system. For keys, choose the attributes that distinguish one disk from another. In the case of a disk, the key attribute is disk number, drive letter, volume label, or whatever is appropriate in your environment. |
| Add this attribute group to a reporting category | Where in the Cognos® data model the attribute group is placed. | Select the check box to place the attribute group in the selected subfolder (Availability or Performance) in the Key Metrics folder. If the check box is not selected, the attribute group is placed in the Extended Metrics folder in the Cognos data model. |
| Metric Category | The category to which the attributes in this attribute group will be assigned. | Select either Performance or Availability. |
For information about the fields for specific data sources, see the chapter for the data source in this user's guide.
