Edit data source and attribute properties
There are a number of ways to begin editing a data source
This documentation covers the following topics that relate to editing data source and attribute properties:
- Create attributes
- Copy attributes
- Edit attributes
- Remove attributes
- Create derived attributes
- Edit derived attributes
- Filtering attribute groups
- Formula Editor
- Formula operators and functions
- Specify operating systems
Procedure
To edit or remove information from a data source (attribute group):
- In the Agent Content area of the Agent Information page click Data Sources. The Data Source Definition page opens.
- Select the data source (attribute group).
The attribute group information area 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, you can double-click the data source to open the Attribute Group Information window. This window has the same information as the attribute group information area of the Data Source Definition page.
(Table 1) 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.
Fields for editing data sources
Field name Description Acceptable values and examples Attribute group name Name of the data source as it is displayed in the Tivoli Enterprise Portal Acceptable values: 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 1 row of data. Editable in all sampled data sources. Example: If you are monitoring physical system memory, choose a single row. 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 you are monitoring disk drives, choose multiple rows because there can be more than one disk in a system. For keys, choose the attributes that distinguish a disk from another. For a disk, the key attribute is disk number, drive letter, volume label, or whatever is appropriate in your environment. Produces Events The data source returns event-based data, 1 row of data per event. Example: An SNMP event-based data source sends notifications (traps) as performance thresholds are crossed. Not all data sources can produce events.
Add this attribute group to a reporting category The category in the generated Cognos model to which the attributes in this attribute group are assigned. 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 are assigned. Select either Performance or Availability.
- The Produce a single data row and Can produce more than one data row fields do not affect data for an event data source.
- For more about sampled and event data types, see (Data types).
- For information about the fields for a specific data source, see the relevant data source chapter in this documentation (Data Sources).
- Create attributes
Adding, modifying, and removing attributes.
- Copy attributes
You can copy attributes from the Data Source Definition page.
- Edit attributes
You can edit and change attribute information using the Agent Editor.
- Remove attributes
Remove an attribute or attributes.
- Create derived attributes
You can create an attribute that derives its value from other attributes instead of directly from the data source.
- Edit derived attributes
Use the Formula Editor to edit derived attributes.
- Filtering attribute groups
You can create a filter to limit the data that is returned from an attribute group that returns sampled data.
- Formula Editor
- Formula operators and functions
A reference (including examples) of formula operators and functions that are used in the formula editor.
- Specify operating systems
When you define data sources that are not specific to the Windows operating system, specify the operating systems where the data source runs.
