Glossary
- additivity flag
-
a flag that is associated with a logger. An additivity
flag controls whether ancestor loggers receive log events. By default,
a log event is passed to the logger that is associated with the event
as well as to any ancestor loggers. If a logger's additivity flag
is set to false, then log events are not passed to ancestor loggers.
For example, if the additivity flag for App.Meta is set to false,
then App.Meta.IO events are passed to the App.Meta.IO and App.Meta
loggers, but they are not passed to the App logger.
- ancestor logger
-
a logger that is at a higher level in relation
to other loggers in the logger hierarchy. For example, the Audit logger
is an ancestor logger of Audit.Meta and Audit.Authentication.
- appender
-
a named entity that represents a specific output
destination for messages. Destinations include fixed files, rolling
files, operating system facilities, and client applications.
- appender additivity
-
a feature that causes each log event to be passed
to the appenders that are associated with the logger as well as to
appenders that are associated with the logger's ancestor loggers.
For example, App.Meta.IO events are passed to appenders that are associated
with App.Meta.IO as well as to appenders that are associated with
App.Meta and App.
- appender reference
-
an expression that identifies an appender whose
destination receives messages for log events for a particular logger.
- Application Response Measurement
-
the name of an application programming interface
that was developed by an industry partnership and which is used to
monitor the availability and performance of software applications.
ARM monitors the application tasks that are important to a particular
business. Short form: ARM.
- ARM
-
See Application Response Measurement.
- ARM agent
-
a software vendor's implementation of the ARM
API. Each ARM agent is a set of executable routines that can be called
by applications. The ARM agent runs concurrently with SAS. The SAS
application passes transaction information to the agent, which collects
the ARM transaction records and writes them to the ARM log.
- autocall macro
-
a macro whose uncompiled source code and text
are stored in an autocall macro library. Unlike a stored compiled
macro, an autocall macro is compiled before execution the first time
it is called.
- conversion character
-
a single character that represents a data item
that is generated in a log event. For example, d specifies the date
of the event and t identifies the thread that generated the event.
- conversion pattern
-
an expression that specifies an appender definition's
pattern layout. A conversion pattern consists of a combination of
user-supplied literal text and conversion specifiers.
- conversion specifier
-
an expression in a conversion pattern that consists
of a percent sign (%), a conversion character, and optional format
modifiers.
- descendant logger
-
a logger that is at a lower level in relation
to other loggers in the logger hierarchy. For example, Audit.Meta
and Audit.Authentication are descendant loggers of the Audit logger.
- diagnostic level
-
the degree of severity of a log event that can
occur during SAS program processing. Examples of levels are trace,
debug, informational, warning, error, and fatal. Short form: level.
- DTD
-
Document Type Definition. A file that specifies
how the markup tags in a group of SGML or XML documents should be
interpreted by an application that displays, prints, or otherwise
processes the documents.
- filter
-
See package filter.
- format modifier
-
an optional set of characters in a conversion
specifier that controls the field width, padding, and justification
of the specified data item in log output.
- Integrated Object Model
-
the set of distributed object interfaces that
make SAS software features available to client applications when SAS
is executed as an object server. Short form: IOM.
- Integrated Object Model server
-
See IOM server.
- IOM
-
See Integrated Object Model.
- IOM server
-
a SAS object server that is launched in order
to fulfill client requests for IOM services. Short form: IOM server.
- level
-
See diagnostic level.
- log
-
See SAS log.
- log event
-
an occurrence that is reported by a program for
possible inclusion in a log.
- logger
-
a named entity that identifies a message category.
Logger names have a hierarchical format that enables you to configure
logging at a broad or a fine-grained level.
- logging configuration
-
an XML file or a set of SAS program statements
that determines how log events are processed. You use the logging
configuration to assign thresholds to loggers, to configure appenders,
and to specify which categories and levels of log events are written
to each appender.
- package filter
-
specified criteria that are applied to data in
order to identify the subset of data for a subsequent operation, such
as continued processing.
- pattern layout
-
a template that you create to format log messages.
The pattern layout identifies the type, order, and format of the data
that is generated in a log event and delivered as output.
- planned deployment
-
a method of installing and configuring a SAS business
intelligence system. This method requires a deployment plan that contains
information about the different hosts that are included in the system
and the software and SAS servers that are to be deployed on each host.
The deployment plan then serves as input to the SAS Deployment Wizard.
- root logger
-
the highest-level logger in the logger hierarchy.
In a logging configuration, all other loggers inherit the root logger's
attributes.
- SAS console log
-
a file that contains information, warning, and
error messages if the SAS log is not active. The SAS console log is
normally used only for fatal system initialization errors or for late-termination
messages.
- SAS Deployment Wizard
-
a cross-platform utility that installs and initially
configures many SAS products. Using a SAS installation data file and,
when appropriate, a deployment plan for its initial input, the wizard
prompts the customer for other necessary input at the start of the
session, so that there is no need to monitor the entire deployment.
- SAS log
-
a file that contains a record of the SAS statements
that you enter, as well as messages about the execution of your program.
- threshold
-
the lowest event level that is processed. Log
events whose levels are below the threshold are ignored.
