You can create a filter to limit the data that is returned
from an attribute group that returns sampled data.
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 IBM® Tivoli® Monitoring or IBM Cloud Application Performance Management.
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
