After loggers and appenders
are defined either in a logging configuration file or a SAS program,
you can add log events to your program. You insert log events at any
point in your program or DATA step that you want to log a message.
A log event takes three arguments: a logger name, a level, and the
log message.
The logger that you
specify in the log event names the message category for the message.
It can be a category that you created in your SAS program or a category
that is defined for SAS servers. The diagnostic level indicates one
of the following diagnostic types for the message: TRACE, DEBUG, INFO,
WARN, ERROR, and FATAL. The log message is the message that you want
to appear in the log. Enclose the message in single or double quotation
marks.
