HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

Discovery filters
Discovery filters are a mechanism to prevent or enable certain system types from ever being added to the
database through automatic discovery . When you want to discover systems of a certain type, using filters
is much easier than specifying the IP addresses of each individual system. Discovery filters do not apply to
manually added systems.
You can access discovery filters in one of the following ways:
• From the Discovery page, select Options→Discovery. From the Automatic tab, click Configure
general settings, and then select Enable discovery filters.
• From the Home page, in the Manage section, click discovery. The Discovery page appears. From
the Automatic tab, click Configure general settings, and then select Enable discovery filters.
• From the introductory page, in the Do this now to complete the installation section, click Automatic.
The Discovery page appears. From the Automatic tab, click Configure general settings, and then
select Enable discovery filters.
To disable filters, clear the Enable discovery filters checkbox. To enable filters, select the Enable discovery
filters checkbox, and then select the system types that you want to discover.
To access and modify discovery filters, you must have administrative rights . If discovery filters are enabled,
only systems of the selected types are added to the database through automatic discovery. Because all tasks
operate on systems that exist in the database, tasks do not run on any system until the filter criteria has been
met and that system has been added to the database. Filters do not affect any systems already discovered,
even if the systems change to a type that no longer matches the current filter. If discovery filters are disabled,
automatic discovery discovers systems according to the General Settings for All Discoveries section on
the Discovery page in the Automatic tab. See “Configuring automatic discovery general settings” for more
information about configuring discovery filters.
If you do not discover the HP systems that you expect to find, ensure that the HP Insight Management Agent s
are installed and running correctly on the target systems. In addition, verify that the SNMP Community Strings
settings and WBEM user name and passwords in HP Systems Insight Manager (HP SIM) and on the agents
for systems that are not discovered are configured correctly. See “Setting global protocols” for more
information.

Managing discovery templates
Discovery templates are files that can be used by automatic discovery instead of entering the addresses
directly in to the Ping inclusion ranges, system (hosts) names, templates, and/or hosts files or Ping
exclusion ranges, templates and/or hosts files fields. You can also add Simple or Fully Qualified Domain
Names (FQDN) host names to discovery templates. However, you cannot enter a range of host names.
Discovery templates can be used as a quick way to change the scope of automatic discovery. See the
"Discovery templates section in “Discovery and identification” section for more information.
NOTE: Saved discovery template files are located in the directory <install
directory>\config\discovery\templates directory.
From the Managing Templates section, you can:
• Create new discovery template files Click New. The Create New Template section appears. See
“Creating a new discovery template file” for more information.
• Edit existing discovery template files Select the discovery template file you want to edit, and then
click Edit. The Edit Template section appears. See “Editing a discovery template” for more information.
• Delete existing discovery template files Select the discovery template file you want to delete, and then
click Delete. A confirmation box appears. See “Deleting a discovery template” for more information.
