The
SAS logging facility enables the categorization and collection of
log event messages, and then writes 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
following features are provided:
-
Log events are categorized using
a hierarchical naming system that enables you to configure logging
at a broad 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 log
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 log events
can be generated for processing by an 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.
In the UNIX operating
environment, logging facility messages can be written to SYSLOGD.
