HP Toptools for Unicenter User Guide
7.4 Discovery and Applications
HP Toptools for Unicenter enhances and extends Unicenter’s discovery in two ways:
• Configuring Unicenter’s discovery to recognize and classify HP SNMP managed devices such as switches and
printers.
• Adding a discovery service that identifies and reclassifies HP systems such as Netservers and PC’s.
As Unicenter is performing discovery, the platform bridge discovery process checks the Repository for likely HP
system candidates (e.g. Windows NT Workstations), and then performs extended discovery on those systems to
determine through DMI and WMI if they are HP PC’s, or through SNMP, if they are HP Netservers. This process
and its progress is visible through the utility HP Reclassification.
At the end of discovery, the platform bridge checks HP Toptools Remote Control cards and HP Netservers for an
association. If one exists, the HP Toptools Remote Control card is placed within the host Netserver’s submap.
Once HP devices are classified within the Repository, menu items and icons associated with their respective classes
become enabled, and the contents of the Repository are sent to the Toptools server.
The Toptools server performs second level discovery to populate MEDS with the data necessary to respond to
requests from the platform bridge on Unicenter’s console (e.g. responding to a request for Property pages).
7.4.1 Event Management
HP Toptools for Unicenter configures Unicenter to recognize and process HP alerts, and to automatically receive
alerts from HP products.
• During the platform bridge discovery process, HP Netservers have their trap destinations automatically set to
send traps to the Unicenter server.
• During discovery, the Toptools server subscribes for DMI and WMI alerts from HP PC’s. The server bridge
configures Toptools to then forward DMI and WMI alerts as SNMP traps to the Unicenter server.
• Customers may use Toptools SNMP/Trap Configuration to configure HP networking devices to send traps
directly to the Unicenter server.
• Customers may use the HP JetDirect Trap Proxy (available in the Contributed Library) to automatically receive,
filter, and forward printer traps to the Unicenter server.
CA Unicenter will natively receive and process SNMP traps through message records and DSM. HP Toptools for
Unicenter provides DSM agents for HP Netservers, HP LaserJets, and HP Toptools Remote Control cards. When
traps are received from these devices, DSM changes the status on the agent which is then propagated up the map.
To reset status on the agent, you must select the agent and the menu item “Reset Status”.
