Deploying Detail Discovery
This section describes how to deploy Detail Discovery.
Detail Discovery Configuration
ADM has an extensive detail discovery feature that enhances and complements the results obtained through
Passive Discovery. Detail Discovery is performed by communication between hosts in a managed network,
using four common network protocols: SNMP, SSH, Telnet, and WMI. Detail discovery is also performed using
the discovery protocol VI ‐ SDK, which is a VMware proprietary API used to query model of VMware, control
the behavior of virtual infrastructure, and receive notifications on changes in the virtual environment.
Using these protocols, supplementary information about network hosts is obtained and added to the
Configuration Management Database (CMDB). To maximize security and minimize the risk of impact on the
managed network, the administrative user of the ADM Console can tightly control the setup and scheduling
of the Detail Discovery queries to the various network hosts.
How Do Active Probe Configurations Affect Detail Discovery Policies?
For Detail Discovery to be successful in a Distributed setup, the hosts to be discovered, needs to be included
in both a Detail Discovery policy and an Active Probe configuration. The Detail Discovery policy includes a
list of items to include in the Detail Discovery, while the Active Probe configuration assigns the specific hosts
on which each Collector can perform Detail Discovery.
Detail Discovery is not be performed on a host that is included in a Detail Discovery policy if it is not included
in an Active Probe configuration. However, the host is still recognized through Passive Discovery and will
appear as Orphaned in the Detail Discovery dashboard because the Active Probe configuration has no
correlation with Passive Discovery.
Detail Discovery Policies
Detail Discovery is controlled and configured through user ‐ defined Detail Discovery policies. There can be
many policies, each describing a query that is running periodically and collecting network information. For
each policy, the following parameters are defined:

The discovery scope, that is, the set of network hosts that is queried for information.

The protocol being used, which is one of the following: SNMP, SSH, Telnet, WMI, or VI ‐ SDK.

Protocol ‐ specific authentication and communication parameters, such as usernames and passwords to
use for authentication.

Scheduling information — How often to access the network hosts covered by the policy. The scheduling
scheme lets ADM users control and balance two conflicting factors: the need to have the most updated
picture, and the need to avoid overloading the network with too many Detail Discovery queries.

Discovery plan — A discovery plan allows you to define exactly what will be discovered, and therefore
improve performance. You can create passive or Detail Discovery plans that can include or exclude the
discovery of specific hosts, services, and connections.

Troubleshooting knowledge base applies only to create a detail discovery support package until the file
is removed. It does not customize the detail discovery knowledge base permanently.

MPORTANT
ADM can merge data from multiple hosts in clustered environment that were assigned the same
IP or secondary IP (such as clusters and balancers) as if only a single host were discovered. You need to inform
your Customer Sales Representative if your network contains more than one host using the same IP so that
ADM is configured to treat each host separately.
