\subsection log_app 1.3 Message appenders

+message to the user. For now, four appenders exist:
+- the default one prints stuff on stderr
+- file sends the data to a single file
+- rollfile overwrites the file when the file grows too large
+- splitfile creates new files with a specific maximum size
-Other are planed (such as the one sending everything to a remote server,
-or the one using only a fixed amount of lines in a file, and rotating content on

\subsection log_lay 1.4 Message layouts
\verbatim --log=root.app:file:mylogfile\endverbatim redirects the output
to the file mylogfile.
+For splitfile appender, the format is
+\verbatim --log=root.app:splitfile:size:mylogfile_%.format\endverbatim
+
+The size is in bytes, and the % wildcard will be replaced by the number of the
+file. If no % is present, it will be appended at the end.
+
+rollfile appender is also available, it can be used as
+\verbatim --log=root.app:rollfile:size:mylogfile\endverbatim
+When the file grows to be larger than the size, it will be emptied and new log
+events will be sent at its beginning
+
Any appender setup this way have its own layout format (simple one by default),
so you may have to change it too afterward. Moreover, the additivity of the log category
is also set to false to prevent log event displayed by this appender to "leak" to any other
option and specify the max file size. This would be a nice default for
non-kernel applications.
- Careful, category names are global variables.
+ - When writing a log format, you often want to use spaces. If you don't
+ protect these spaces, they are used as configuration elements separators.
+ For example, if you want to remove the date from the logs, you want to pass the following
+ argument on the command line. The outer quotes are here to protect the string from the shell
+ interpretation while the inner ones are there to prevent simgrid from splitting the string
+ in several log parameters (that would be invalid).
+ \verbatim --log="'root.fmt:%l: [%p/%c]: %m%n'"\endverbatim
+ Another option is to use the SimGrid-specific format directive \%e for
+ spaces, like in the following.
+ \verbatim --log="root.fmt:%l:%e[%p/%c]:%e%m%n"\endverbatim
\section log_internals 4. Internal considerations
its additivity set to true. This causes all messages to be logged by the root
category's appender.
-The default appender function currently prints to stderr, and the only other
-existing one writes to the specified file. More would be needed, like the one
-able to send the logs to a remote dedicated server.
-This is on our TODO list for quite a while now, but your help would be
-welcome here, too. */
