The SAS logging facility
makes it possible to categorize, collect, and filter log events and
write them to a variety of output devices. The logging facility supports
problem diagnosis and resolution, performance and capacity management,
and auditing and regulatory compliance. The logging facility has following
features:
-
Log events are categorized using
a hierarchical naming system that enables you to configure logging
at a broad level or a fine-grained level.
-
Log events can be directed to multiple
output destinations, including files, operating system facilities,
databases, and client applications. For each output destination, you
can specify:
-
the categories and levels of events
to report
-
the message layout, including the
types of data to be included, the order of the data, and the format
of the data
-
filters based on criteria such
as diagnostic levels and message content
-
Logging diagnostic levels can be
adjusted dynamically without starting and stopping processes.
-
Performance-related events can be generated for processing by the Application Response
Measurement (ARM) 4.0
server.
The logging facility is used by most SAS server processes. You can also use the logging
facility within SAS programs.
For Windows, log messages
can be written to the Windows event viewer.

using the logging facility in your operating environment, see SAS Logging: Configuration and Programming Reference.
