Essential Concepts
Table 1 ‐ 1 defines essential concepts of ADM.
ADM Components
VMware provides ADM on one or more appliances. The mode of the appliance determines which component
is running. ADM components are described in Table 1 ‐ 2 .
Table 1-1. Essential Concepts
Concept Definition
Configuration Item (CI) A CI is a host (this can also include network devices such as switches or routers), an
application (also known as a service), or a network connection. For example, a Linux
host, Cisco router, or VMware® ESX™ Server are all host CIs. Oracle is an application
CI. HTTP and SSH are network connection CIs.
Discovery Discovery is a continuous process that creates and maintains a detailed model of your
application environment. ADM discovers CIs. Chapter 5 contains more information
about discovery.
Management Data
Repository (MDR)
The MDR is the database of ADM. When configuration item information is
discovered, it is stored in the MDR after reconciliation.
Groups A group is a built ‐ in or user ‐ defined collection of one or more CIs. The admin users can
create groups so that they can easily view, analyze, and track the specific subset of
data. Group creation allows the admin user to classify CIs into logical sets or
collections so that actions such as creating reports, policies, or viewing the inventory
is applied to specific groups, instead of the entire database of CIs. Chapter 4 contains
more information about groups.
Change A change is any change to a CI. For example, a change to a configuration file on a host
is a change.
Change tracking Change tracking refers to a change in the discovered environment, such as a change
in the amount of activity on a host, a change in the demand on a host or service, or a
new host or connection that is present in the discovered environment. Change
tracking refers to behavioral changes. ADM allows you to create change tracking
policies that track behavioral changes in your application environment.
Application pattern ADM discovers business applications by creating application patterns. The admin user
can create these from the Manage tab, or a VMware Professional Services
representative can provide you these. An application pattern definition consists of a
set of rules — node rules and connectivity rules — that describe the requested pattern.
ADM analyzes the application pattern definition and discovers instances of the
application pattern. Node rules are group ‐ like rules that describe the instances in the
topology graph. Connectivity rules describe the edges in the topology graph (that is,
the connectivity between two instances).
Entity aging ADM lets you create entity aging policies. For example, a service running in your
network is populated in the MDR, and is therefore visible to you from the User
Interface (UI). If you uninstall this service at a later time, you should no longer see it
as a running service in the UI. Creating an entity aging policy lets you view the most
updated state of your network, since it is a constantly changing environment. (An
entity is a network element, service or dependency, and any of their derived elements
such as a J2EE or database instance.)
