SQL queries to ODBC datasources for
retrieval and display in table and chart
views.
subnetwork
A configuration wherein a single IP
network address is split up so it can be
used on several interconnected local
networks. Subnetworking is a local
configuration; outside it appears as a
single IP network.

summarization and pruning agent
One of the Tivoli Monitoring base agents,
the summarization and pruning agent is
used to keep the data warehouse from
growing too large by summarizing and
pruning your stored historical data at
intervals that you set. For every attribute
group that has data collection configured,
you specify how often to aggregate
(summarize) data in the Tivoli Data
Warehouse and the length of time to
delete (prune) data from the warehouse.
symbol
Represents a variable that can be added
to header or footer text for data views,
expert-advice text, or query specification.
The detailed attribute name is enclosed in
dollar signs, such as $ORIGINNODE$, and
resolves to the attribute's value. For Tivoli
Enterprise Monitoring Server queries, ==
$NODE$ specifies the managed systems
from which to retrieve data. For queries
to be used in link target workspaces, you
can create symbols for attributes using the
$symbolname$ format.
System Monitor Agent
These agents were introduced with IBM
Tivoli Monitoring V6.2.2 for nodes that
run the desktop operating systems
(Windows, Linux, UNIX). These agents
operate only autonomously (that is, they
run without a connection to a Tivoli
Enterprise Monitoring Server) and pass
SNMP trap data about operating system
performance to an SNMP Event Collector
such as IBM Tivoli Netcool/OMNIbus's
MTTRAPD receiver.
No other IBM Tivoli Monitoring agents or
other components should be installed on
the same node as a System Monitor
Agent. The only exception to this rule is
agents created with the Agent Builder tool
for V6.2.2 or subsequent.
System Service Monitors
The IBM Tivoli Netcool/OMNIbus
product provides System Service Monitors
that support basic system-level
monitoring of network components such
as operating systems. In addition,
OMNIbus provides ISMs (Internet Service
Monitors) and ASMs (Application Service
Monitors).
Take Action
A Tivoli Enterprise Portal dialog box from
which you can enter a command or
choose from a list of predefined
commands. It also lists systems on which
to effect the command, which is usually a
response to an event.
Take Action command
A Take Action command allows you to
send commands to your managed
systems, either automatically, in response
to a situation that has fired (that is,
turned true), or manually, as the Tivoli
Enterprise Portal operator requires. With
Take Action commands, you can enter a
command or select one of the commands
predefined by your product and run it on
any system in your managed network.
Thus you can issue Take Action
commands either against the managed
system where the situation fired or a
different managed system in your
network.
target libraries
SMP/E-controlled libraries that contain
the data installed from the distribution
media.
TCP/IP
See Transmission Control
Protocol/Internet Protocol.
TDW See Tivoli Data Warehouse.
telnet A terminal emulation program used on
TCP/IP networks. You can start a telnet
session with another system and enter
commands that execute on that system. A
valid user ID and password for that
remote system are required.
threshold
A level set in the system at which a
message is sent or an error-handling
program is called. For example, in a user
