Discovery data selected for the CMDB

Use the controls in the Discovery configuration console to select the device, application, and software data you want to add to the CMDB.


Use the switches in the console to determine if a configuration item (CI) is discovered. The switch turns gray when an item is excluded. When you configure Discovery to ignore a CI, the instance disables the probe or classifier that explores that CI.
Note: This action does not deactivate the probe or classifier for general use across the system. The item remains available for other processes.
You can prevent the discovery of network devices, storage devices, and computers. Blocking device data at the top level disables the related port probes. For example, blocking Network Devices disables the SNMP port probe. Blocking devices at the second level of the hierarchy has the following effects:
  • Device class categories disable classifiers.
  • Device info categories disable probes executed by classifiers.

Data blocked at the second level of the hierarchy effects the nested subclasses. For example, if you block Windows Servers & Computers data, the system also blocks data from nested subclasses, since those classes are all dependent on the port probes that are disabled.


Disabling the discovery of application data affects all host devices on which the application runs. For example, if you configure Discovery to ignore databases, no information is gathered for either Linux or Windows databases. Conversely, if you configure the system to ignore a device type, such as a Windows server, no databases running on that server are explored, even if they are configured to be discovered. The instance cannot identify the applications running on a server until it first discovers that server.

When you exclude an item from the Applications section, the system disables the relevant process classifier.


You can configure which Windows and UNIX software packages identfied by Disccovery are stored in the CMDB.

Discovery provides configurable lists of keywords it can use to filter software packages for Windows and UNIX operating systems. A filtering keyword can be any term that is present in a software package name that you want to use to filter the results of a Discovery. You can choose to include or exclude packages with names that contain the keywords defined in these lists.

Keywords for filtering software are stored in the Software Filter Keys [discovery_spkg_keys] table. The following default keywords are provided for Windows:
  • Hotfix
  • Language Pack
  • Security Update
Note: The system does not provide default filtering keywords for UNIX software.
