Discovery Configuration Console

The Discovery Configuration Console allows you to manage what kind of CIs and CI information you want to discover.

By default, Discovery finds all the information on your network that is specified in probes and patterns. Use the Discovery Configuration Console to prevent Discovery from finding data that your organization does not need. You can control several aspects of discovery:
  • The discovery of entire CI types, such as Windows servers.
  • The discovery of specific CI details, such as OS information on Windows servers.
  • The discovery of software packages containing keyword terms that you add, such as Hotfix or Security Update.

Requirements and accessibility

If you use Internet Explorer, you must use version 8 and later.

The configuration console supports these accessibility features:
  • Keyboard navigation
  • Screen readers

Console overview

The console is divided into these sections:
  • Devices: network devices such a printers, storage devices such as storage switches, and Unix and Windows computers.
  • Applications: automation applications such as Puppet, databases such as MSSQL, and web servers such as Tomcat.
  • Software Filter: Unix and Windows applications that include or exclude keywords that you enter.
The Discovery Configuration Console

Device discovery

Disabling the discovery of device data at the top level disables the related port probes and pattern libraries. 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 and pattern libraries.

Application discovery

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. The probes that belong to this classifier, including the Horizontal Pattern probe that launches patterns, never launch.

Software discovery

Filtering out the discovery of software based on the keywords they contain affects all software packages on Windows and UNIX computers. A keyword can be any term that is present in a software package name.

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

Affects on Discovery tables

This table shows you what is disabled in Discovery tables when you use the Discovery Configuration Console.

When you disable Field disabled
Top level device categories, such as:
  • Network Devices
  • Windows Servers & Computers
  • Unix Servers & Computers

The CIs field is disabled on the Port probes [discovery_port_probe] table.

The Port probes [discovery_port_probe] table is referred to from the Protocol Category [discovery_category_protocol] table.

Device classes, such as:
  • Windows 2008 Servers
  • Linux Servers

The Active field is disabled on the Classifiers [discovery_classy] table for the related classifier.

The Classifiers [discovery_classy] table is referred to from the Device Classification Category [discovery_category_device_class] table.

Device info, such as:
  • Network Device Exploration
  • Windows Storage

The Active field is disabled on both the Classifier Probes [discovery_classifier_probe] and the Discovery Patterns [sa_pattern] tables for the related probe or pattern library that performs the identification and exploration of the CI.

These tables are referred to from the Device Info Category [discovery_category_device_info] table.

Applications

The Active field is disabled on the Process Classifiers [discovery_classy_proc] table for the related process classifier.

The Process Classifiers [discovery_classy_proc] table is referred to from the Application Category [discovery_category_appl] table.

Note: If you use patterns for discovery, and you disable the discovery of device classes or device information, the system disables the pattern libraries that collect the device information. For example, if you have a Windows pattern in which you create a shared library that collects OS information, and then you disable the collection of OS data, the shared library that collects OS data is disabled. See Reuse a shared step library for more information about the shared library operation.
