Universal Discovery

Jump to solution

Can you please provide an example of the difference in the resulting data collected by the agented UD and the agentless version?

IE does the agentless get down to the .dll? Will it do any software utilization? What is missing between agentless and agented discovery?

The Data Flow Management Guide http://support.openview.hp.com/selfsolve/document/KM00245427

has the following information:

 

Agent-Based vs Agentless Discovery Overview

Agent-Based Discovery

To collect inventory information, you can deploy Universal Discovery agents on client or server

machines. The UD agent provides a secured communication channel between the Data Flow Probe

and the Nodes being discovered. After setting up the secure communication channel, Universal

Discovery deploys and activates scanners onto the Nodes being discovered. The Scanners scan

the Nodes for inventory information and store the scanned results in scan files which are

downloaded to the Data Flow Probe through the secured communication channel established with

the UD agent.

When the UD agent is installed, collection of software utilization information is enabled. The

UD Agent also enables you to benefit from the Call Home feature. Call Home is useful in the case

where a Node was unavailable for scanning for a long period. It enables the UD agent to notify the

Data Flow Probe that the Node is currently available for scanning.

Agentless Discovery

Although agentless discovery does not require the installation of dedicated agents on the servers

that are to be discovered, it does depend on native OS or standard agents that are already installed

such as SNMP, WMI, TELNET, SSH, NETBIOS, and others. Other discovery capabilities are

based on application-specific protocols such as SQL, JMX, SAP, Siebel, and so on. For details on

supported protocols, see the HP Universal CMDB Discovery and Integration Content Guide.

 

Only agent-based does software utilization, and dlls are used in SAI (Software Application Index) to identify applications.

I have attached a couple of files, one discovery by UD and the other for Host Applications by WMI for your reference.

 

Regards,

Juan

Hi Qingc,

 

I have attached a copy of sample one with UDA the other Host application by WMI. I hope this time gets attached.
