I have done this with a trivial C program, piping the log stream stdin to stdout, putting a time stamp in front of the first character of each (not blank?) line. When C read()'s one byte at a time, it tends to force lowest latency. In ksh on /dev/fd/ systems and in bash, you can make the log file >(...), or you can manage a named pipe.

ated.
The ds.log fields are:
date
The date format is mmm nn, where mmm is the local three-character abbreviation for the month and nn is the day of the month on which
the event occurred.
time
The time of the event, in hh:mm:ss format.
product
A product code that identifies which component of the data services produced the event. The code is separated from the message that
follows by a colon (:) and a space.
message
A message that can extend over more than one line describing the event that occurred. The second or following lines are not pre-
fixed by the date, time, and product code strings.
