IBM Tivoli Access Manager for e-business: WebSEAL Administration ...

Specifying
the
frequency
for
flushing
log
file
buffers
Log
files
are
written
to
buffered
data
streams.
If
you
are
monitoring
the
log
files
in
real
time,
you
might
want
to
alter
the
frequency
with
which
the
server
forces
a
flush
of
the
log
file
buffers.
By
default,
log
files
are
flushed
every
20
seconds:
[logging]
flush-time
=
20
If
you
specify
a
negative
value,
a
flush
will
be
forced
after
every
record
is
written.
