+dit(bf(log format)) The "log format" option allows you to specify the
+format used for logging file transfers when transfer logging is
+enabled. The format is a text string containing embedded single
+character escape sequences prefixed with a percent (%) character.
+
+The prefixes that are understood are:
+
+itemize(
+ it() %h for the remote host name
+ it() %a for the remote IP address
+ it() %l for the length of the file in bytes
+ it() %p for the process id of this rsync session
+ it() %o for the operation, which is either "send" or "recv"
+ it() %f for the filename
+ it() %P for the module path
+ it() %m for the module name
+ it() %t for the current time
+ it() %u for the authenticated username (or the null string)
+ it() %b for the number of bytes actually transferred
+ it() %c when sending files this gives the number of checksum bytes
+ received for this file
+)
+
+The default log format is "%o %h [%a] %m (%u) %f %l"
+
+A perl script called rsyncstats to summarise this format is included
+in the rsync source code distribution.
