Configuring automatic discovery
When you access the A utomatic tab on the Discovery page, a table displays a list of all available discovery
tasks. You can configure multiple instances of discovery with each instance having its own schedule and set
of inclusion ranges. When a discovery task is executed, the Last Run column is updated to display its
progress, including the percentage of completion.
Automatic discovery and completion percentages are calculated by weighting two factors: the ping sweep
(performed on each host) is 10% of the process; the system identification is 90% of the process. If no host
is found on an IP address, the system identification is considered complete. For example, you have 100
hosts in your discovery range. If 50 hosts have been pinged, but only 10 identified, you have: 50/100 *
.10 = 0.05 (ping sweep) 10/100 * .90 = 0.09 (identification) 0.05 + 0.09 = 0.14 * 100 = 14% (total
completed percentage).
NOTE: Only one discovery task can run at a time. If you select to run more than one discovery task, the
percentage in the Last Run column remains at 0% until the currently running task is complete.
Under the For all automatic discoveries section, the following options are available:
• Configure general settings Used to configure settings that apply to all discovery tasks. See “Configuring
automatic discovery general settings” for more information.
• Manage templates Used to manage discovery templates. See “Managing discovery templates” for
more information.
• Configure global protocol settings Used to configure global protocol settings. See “Setting global
protocols” for more information.
Note: To discover clusters correctly, SNMP must be enabled with the correct security settings on HP
Systems Insight Manager (HP SIM) and running on the target systems.
Note: Desktop Management Interface (DMI) identification is only supported on Windows and
HP-UX-based Central Management Server (CMS) installations and only like operating systems are
identified. For example, a Windows-based CMS identifies only Windows-based DMI systems, and an
HP-UX-based CMS identifies only HP-UX-based DMI systems.
