HP Systems Insight Manager 5.2 Update 2 Technical Reference Guide

adds any systems that send SNMP traps , WBEM indications, or other events to HP SIM that do not have a
matching IP address in the database. The option, Ping exclusion ranges, templates, and/or hosts files,
allows the entry of any IP addresses that you want excluded from event-based automatic discovery. If SNMP
is disabled on the Global Protocols Settings page under Options→Protocol Settings→Global Protocol
Settings, then SNMP traps are ignored. If WBEM is disabled, WBEM indications are also ignored.
NOTE: With the exception of the SNMP Authentication Failure trap, all traps trigger an automatic discovery.
Discovery templates
Discovery templates are files that can be used by automatic discovery instead of typing addresses directly
into the fields, Ping inclusion ranges, system (hosts) names, templates, and/or hosts files or Ping
exclusion ranges, templates and/or hosts files. The templates can be used as a way to quickly change
the scope of automatic discovery and are used each time discovery runs. To access the discovery template
section, click the Automatic tab from the Discovery page and then click Manage templates.
For example, you can configure a discovery template with a broad range of addresses that are discovered
infrequently when you want to issue a broad range ping. When necessary, the template can be used to
input the Ping inclusion ranges, system (hosts) names, templates, and/or hosts files field of the Edit
Discovery section. To access this section, select Options→Discovery, click the Automatic tab, and then
click Edit. The templates also enable you to quickly change the scope of discovery without having to cut
and paste addresses or manually reenter the ranges.
After creating a discovery template, to reference it in automatic discovery, enter @template_name in the
fields Ping inclusion ranges, system (hosts) names, templates, and/or hosts files or Exclusion
ranges, templates and/or hosts files. See “IP ranges” for more information.
NOTE: Because discovery now supports multiple schedules and configurations (ranges), the need for
templates is significantly reduced. HP recommends that you leverage several different discovery schedules
and configurations instead of using discovery templates.
NOTE: A single discovery template cannot include both included and excluded ranges. You must create
a separate template for use in each field of automatic discovery. Template files cannot be nested, that is, a
template file cannot contain another template file name through the @template_name reference.
When configuring automatic discovery, the format of a discovery template is the same as that used in the
Ping inclusion ranges, system (hosts) names, templates, and/or hosts files and Ping exclusion
ranges, templates and/or hosts files.
Access discovery templates by clicking Manage templates under the section, For all automatic discoveries
section on the Discovery page. See “Managing discovery templates” for information about creating a
discovery template file.
First discovery
You can start a discovery in the following ways:
• Execute discovery immediately from the Discovery→Automatic page, select the discovery task, click
Edit to configure the discovery task for your environment, and then click Run Now. The discovery
process starts immediately. The discovery progress is updated as the systems are discovered, until the
discovery process is complete.
• Allow sufficient time for a complete discovery and identification to be performed. Times vary, depending
on your network, bandwidth, and discovery settings. In most cases, the discovery process finds all
systems by pinging the network.
Subsequent discoveries
You can run discovery any time from the Discovery→Automatic page. For subsequent discoveries, you
can specify the subnets or systems to interrogate and the schedule to follow.
For the most comprehensive discovery and identification, always select SNMP, Desktop Management Interface
(DMI), Web-Based Enterprise Management (WBEM), and HTTP as the protocols on the Options→Protocol
