Glossary

activity
One phase within a sequence of
predefined steps called a policy that
automate system responses to a situation
that has fired (that is, become true).
administration mode
See workspace administration mode.
Advanced Encryption Standard
An encryption algorithm for securing
sensitive but unclassified material
designed by the National Institute of
Standards and Technology (NIST) of the
U.S. Department of Commerce. AES is
intended to be a more robust replacement
for the Data Encryption Standard. The
specification calls for a symmetric
algorithm (in which the same key is used
for both encryption and decryption),
using block encryption of 128 bits and
supporting key sizes of 128, 192 and 256
bits. The algorithm was required to offer
security of a sufficient level to protect
data for the next 20 to 30 years. It had to
be easily implemented in hardware and
software and had to offer good defenses
against various attack techniques. AES
has been published as Federal
Information Processing Standard (FIPS)
197, which specifies the encryption
algorithm that all sensitive, unclassified
documents must use.
AES See Advanced Encryption Standard.
affinity
A label that classifies objects by managed
system.
agent Software installed on systems you want to
monitor that collects data about an
operating system, subsystem, or
application running on each such system.
Because an executable file gathers
information about a managed system,
there is always a one-to-one
correspondence between them. Also called
a Tivoli Enterprise Monitoring Agent.
agentless monitor
An agentless monitor uses a standard API
(such as SNMP or CIM) to identify and
notify you of common problems with the

operating system running on a remote
computer. Thus, as their name implies,
the agentless monitors can retrieve
monitoring and performance data
without requiring OS agents on the
computers being monitored. The agentless
monitors provide monitoring, data
gathering, and event management for
Windows, Linux, AIX, HP-UX, and Solaris
systems.
agentless monitoring server
A computer with an OS agent installed
that has one or more agentless monitors
running on it. Each agentless monitoring
server can support up to 10 active
instances of the various types of agentless
monitors, in any combination. Each
instance can communicate with up to 100
remote nodes, which means a single
agentless monitoring server can support
as many as 1000 monitored systems.
alert A warning message that appears at a
console to indicate that something has
occurred that might require intervention.
API See Application Programming Interface.
application
A software component or collection of
software components that performs
specific user-oriented work (a task) on a
computer. Examples include payroll,
inventory-management, and
word-processing applications.
Application Programming Interface
A set of multiple subprograms and data
structures and the rules for using them
that enables application development
using a particular language and, often, a
particular operating environment. An API
is a functional interface supplied by the
operating system or by a separately
licensed program that allows an
application program written in a
high-level language to use specific data or
functions of the operating system or the
licensed program.
associate
The process of linking a situation with a
Navigator item that enables a light to go
