Discovery Plans
A discovery plan helps you to control the depth of information discovered. For example, software changes
frequently and hardware does not change often. Therefore, you might want to discover software information
more often than hardware information. A discovery plan allows you to define exactly what will be discovered,
and therefore improves performance. ADM lets you include or exclude both the passive and detail discovery
of specific hosts, services, and connections with the creation of passive discovery plans and detail discovery
plans. “Passive Discovery” on page 32 contains information on passive discovery plans, and “Detail
Discovery” on page 33 contains information on detail discovery plans.
Passive Discovery
Passive Discovery detects hosts, services, relationships and dependencies. Further, it detects the use of each
relationship, extracts some basic properties (that is, URLs, table names, version numbers), and resolves IPs to
host names.
Policies
Start Passive Discovery after creating a Passive Discovery policy in which you specify an IP address range to
search for traffic and hosts. Navigate to Manage > Passive Discovery to view the Passive Discovery Policy
Definition screen and create a policy. The online help contains procedural information for Passive Discovery
tasks.
Plans
You can create a Passive Discovery plan from the Plan tab within the Passive Discovery Policy Definition
screen.
To create a Passive Discovery plan
1 Select the discovery plan rules. You have an option to discover, not to discover and ignore the following:

Services

Protocols

Ports

Service categories
2 Select or clear Discover behavior option.
3 Click Update.
Passive Discovery plans are useful when you want to include or exclude the passive discovery of certain hosts,
services, or connections. This will also improve performance. Scenarios in which you might want to create a
Passive Discovery plan are as follows:

The SSH protocol is noisy and clutters the MDR without providing any value. Since you are not interested
in discovering the SSH protocol passively, you can specify this in the Passive Discovery plan.

For licensing control, you want to include or exclude only certain discovery services such as BEA OEM.
IP Discovery
IP Discovery is a method for detecting hosts or other configuration items with a specific IP address when
passive discovery fails to find them. For example, if a host is powered down or if it is outside the specified IP
range, passive discovery fails to find it. In this case, you can use IP discovery with a TCP or ICMP connection
to find CIs. IP discovery policies are created from the Manage > IP Discovery page.
