Specifying filter inclusions and exclusions
You can specify particular resources or filters to include or exclude in your filter.
The filters that you include or exclude may contain further filters. You can select
resources and filters from the list of those available in the CMDB, and you can
also import resources from a .csv file.
See “Creating or modifying a filter” on page 298.
If you import resources from a .csv file, the file may identify a computer by name,
fully qualified domain name, or IP address. Any item that is not found in theCMDB
is ignored.
The filter membership is determined by adding the inclusions to the query results,
and then removing the exclusions. Filters and resources have no difference in
priority.
To specify resources to include or exclude
1 In the Symantec Management Console, in the Manage menu, click Filters.
2 In the left pane, click the filter that you want to modify.
3 On the Filter Name page, in the Filter Definition panel, under Explicit
Inclusions and Exclusions, do any of the following:
To include selected resources 1 Under Inclusions, click Select a resource.
2 In the Select Resources window, select the
resources that you want to include, and then click OK.
To include resources listed in a file 1 Under Inclusions, click Import from a file.
