You can create a filter to limit the data that is returned
from an attribute group that returns sampled data.
Before you begin
If the attribute group exists, open the Data
Source Definition page. For more information, see The Data Source Definition page.
If you want to create
an attribute group, follow the steps in (Defining initial data source) and click Advanced in the initial data source information page.
Procedure
- Use one of the following steps to begin creating the filter:
- If you are creating an attribute group, click Advanced in the initial data source information page.
- If the attribute group exists, select the attribute group
in the Data Source Definition page and click Advanced in the Data Source Definition page.
- In the Advanced Data Source Properties page, enter a selection formula. The selection formula that you
enter must evaluate to a Boolean result, true, or false. In the Advanced Data Source Properties page,
you can click Edit to enter or modify the formula
by using the Formula Editor. For more information about the Formula
Editor, see Formula Editor
- When you finish entering the filter selection formula,
click OK until you return to the Data Source Definition page. When the
filter is created, the agent uses the filter to evaluate each row
of data. When the filter evaluates to true for
a row of data, the data is sent to Tivoli® Monitoring. When the filter evaluates to false, the row of data is not sent and is discarded.
What to do next
You can validate that the filter is working as intended
by using the test function for the attribute group. For more information
about attribute group testing, see Attribute group testing
